供稿：網(wǎng)友

前言

         最近比較閑，復(fù)習(xí)搭建一下項目，這次主要使用sPRing+SpringMVC+Mybatis。項目持久層使用Mybatis3，控制層使用SpringMVC4.1，使用Spring4.1管理控制器，數(shù)據(jù)庫連接池使用druid數(shù)據(jù)源，該項數(shù)據(jù)庫暫使用MySQL。

1、 數(shù)據(jù)庫表結(jié)構(gòu)以及maven項目結(jié)構(gòu)

         數(shù)據(jù)表非常的簡單（不是重點），如下：

        

       創(chuàng)建maven項目，詳細見上一篇maven創(chuàng)建（http://blog.csdn.net/fengshizty/article/details/43019561），創(chuàng)建Maven Project時，將Filter選擇為org.apache.maven.archetypes。填寫完相關(guān)項目坐標(biāo)信息后項目結(jié)構(gòu)如下：

       

     注：若無src/main/java，src/test/java，src/test/resources時，創(chuàng)建這個幾個Source Folder。

 2、修改pom.xml添加對應(yīng)的包依賴

     這兒將全部使用的Maven依賴貼出了，對應(yīng)什么作用上面都有解釋，如下：

     pom.xml

[html] view plain copy 在CODE上查看代碼片<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">      <modelVersion>4.0.0</modelVersion>      <groupId>org.andy.sm</groupId>      <artifactId>springmvc_mybatis_demo</artifactId>      <packaging>war</packaging>      <version>0.0.1-SNAPSHOT</version>        <name>springmvc_mybatis_demo Maven Webapp</name>      <url>http://maven.apache.org</url>        <properties>          <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>          <spring.version>4.1.4.RELEASE</spring.version>          <jackson.version>2.5.0</jackson.version>      </properties>        <dependencies>            <dependency>              <groupId>junit</groupId>              <artifactId>junit</artifactId>              <version>4.12</version>              <scope>test</scope>          </dependency>            <!-- spring -->          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-core</artifactId>              <version>${spring.version}</version>          </dependency>            <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-beans</artifactId>              <version>${spring.version}</version>          </dependency>            <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-context</artifactId>              <version>${spring.version}</version>          </dependency>            <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-tx</artifactId>              <version>${spring.version}</version>          </dependency>            <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-web</artifactId>              <version>${spring.version}</version>          </dependency>            <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-webmvc</artifactId>              <version>${spring.version}</version>          </dependency>            <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-jdbc</artifactId>              <version>${spring.version}</version>          </dependency>            <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-test</artifactId>              <version>${spring.version}</version>              <scope>test</scope>          </dependency>            <!-- mybatis 包 -->          <dependency>              <groupId>org.mybatis</groupId>              <artifactId>mybatis</artifactId>              <version>3.2.8</version>          </dependency>            <!--mybatis spring 插件 -->          <dependency>              <groupId>org.mybatis</groupId>              <artifactId>mybatis-spring</artifactId>              <version>1.2.2</version>          </dependency>            <!-- mysql連接 -->          <dependency>              <groupId>mysql</groupId>              <artifactId>mysql-connector-java</artifactId>              <version>5.1.34</version>          </dependency>            <!-- 數(shù)據(jù)源 -->          <dependency>              <groupId>com.alibaba</groupId>              <artifactId>druid</artifactId>              <version>1.0.12</version>          </dependency>            <dependency>              <groupId>org.aspectj</groupId>              <artifactId>aspectjweaver</artifactId>              <version>1.8.4</version>          </dependency>            <!-- log4j -->          <dependency>              <groupId>log4j</groupId>              <artifactId>log4j</artifactId>              <version>1.2.17</version>          </dependency>            <!-- servlet -->          <dependency>              <groupId>javax.servlet</groupId>              <artifactId>servlet-api</artifactId>              <version>3.0-alpha-1</version>          </dependency>            <dependency>              <groupId>javax.servlet</groupId>              <artifactId>jstl</artifactId>              <version>1.2</version>          </dependency>            <!-- json -->          <dependency>              <groupId>org.codehaus.jackson</groupId>              <artifactId>jackson-mapper-asl</artifactId>              <version>1.9.13</version>          </dependency>            <dependency>              <groupId>com.alibaba</groupId>              <artifactId>fastjson</artifactId>              <version>1.2.3</version>          </dependency>            <dependency>              <groupId>com.fasterxml.jackson.core</groupId>              <artifactId>jackson-annotations</artifactId>              <version>${jackson.version}</version>          </dependency>            <dependency>              <groupId>com.fasterxml.jackson.core</groupId>              <artifactId>jackson-core</artifactId>              <version>${jackson.version}</version>

4、引入Spring并配置相關(guān)屬性

    %20在src/main/resources創(chuàng)建spring的配置文件，這里創(chuàng)建了spring.xml，信息如下：

   %20

[html]%20view%20plain%20copy%20<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"      xsi:schemaLocation="http://www.springframework.org/schema/beans              http://www.springframework.org/schema/beans/spring-beans-4.1.xsd              http://www.springframework.org/schema/context              http://www.springframework.org/schema/context/spring-context-4.1.xsd">        <!--引入配置屬性文件 -->      <context:property-placeholder location="classpath:config.properties" />        <!--自動掃描含有@Service將其注入為bean -->      <context:component-scan base-package="org.andy.shop.service" />    </beans>  

5、引入Mybatis并配置數(shù)據(jù)連接池等信息

 5.1、數(shù)據(jù)連接池druid配置信息%20

  %20配置連接池配置信息在config.properties中，如下：

 %20

[plain]%20view%20plain%20copy%20#mysql version database druid setting  validationQuery=SELECT 1  jdbc.url=jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8  jdbc.username=root  jdbc.passWord=12345  

5.2、配置Mybatis相關(guān)信息

   %20以下是mybatis的配置信息：spring-mybatis.xml（ps：名字可隨便起）

[html]%20view%20plain%20copy%20<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"      xmlns:aop="http://www.springframework.org/schema/aop"      xsi:schemaLocation="          http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-4.1.xsd           http://www.springframework.org/schema/tx           http://www.springframework.org/schema/tx/spring-tx-4.1.xsd          http://www.springframework.org/schema/aop           http://www.springframework.org/schema/aop/spring-aop-4.1.xsd          ">        <!-- 配置數(shù)據(jù)源 使用的是Druid數(shù)據(jù)源 -->      <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource"          init-method="init" destroy-method="close">          <property name="url" value="${jdbc.url}" />          <property name="username" value="${jdbc.username}" />          <property name="password" value="${jdbc.password}" />            <!-- 初始化連接大小 -->          <property name="initialSize" value="0" />          <!-- 連接池最大使用連接數(shù)量 -->          <property name="maxActive" value="20" />                    <!-- 連接池最小空閑 -->          <property name="minIdle" value="0" />          <!-- 獲取連接最大等待時間 -->          <property name="maxWait" value="60000" />          <property name="poolPreparedStatements" value="true" />          <property name="maxPoolPreparedStatementPerConnectionSize"              value="33" />          <!-- 用來檢測有效sql -->          <property name="validationQuery" value="${validationQuery}" />          <property name="testOnBorrow" value="false" />          <property name="testOnReturn" value="false" />          <property name="testWhileIdle" value="true" />          <!-- 配置間隔多久才進行一次檢測，檢測需要關(guān)閉的空閑連接，單位是毫秒 -->          <property name="timeBetweenEvictionRunsMillis" value="60000" />          <!-- 配置一個連接在池中最小生存的時間，單位是毫秒 -->          <property name="minEvictableIdleTimeMillis" value="25200000" />          <!-- 打開removeAbandoned功能 -->          <property name="removeAbandoned" value="true" />          <!-- 1800秒，也就是30分鐘 -->          <property name="removeAbandonedTimeout" value="1800" />          <!-- 關(guān)閉abanded連接時輸出錯誤日志 -->          <property name="logAbandoned" value="true" />          <!-- 監(jiān)控數(shù)據(jù)庫 -->          <property name="filters" value="mergeStat" />      </bean>        <!-- myBatis文件 -->      <bean id="sqlsessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">          <property name="dataSource" ref="dataSource" />          <!-- 自動掃描entity目錄, 省掉Configuration.xml里的手工配置 -->          <property name="mapperLocations" value="classpath:org/andy/shop/mapping/*.xml" />      </bean>        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">          <property name="basePackage" value="org.andy.shop.dao" />          <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />      </bean>        <!-- 配置事務(wù)管理器 -->      <bean id="transactionManager"          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">          <property name="dataSource" ref="dataSource" />      </bean>        <!-- 注解方式配置事物 -->      <!-- <tx:annotation-driven transaction-manager="transactionManager" /> -->        <!-- 攔截器方式配置事物 -->      <tx:advice id="transactionAdvice" transaction-manager="transactionManager">          <tx:attributes>              <tx:method name="insert*" propagation="REQUIRED" />              <tx:method name="update*" propagation="REQUIRED" />              <tx:method name="delete*" propagation="REQUIRED" />                <tx:method name="get*" propagation="SUPPORTS" read-only="true" />              <tx:method name="find*" propagation="SUPPORTS" read-only="true" />              <tx:method name="select*" propagation="SUPPORTS" read-only="true" />            </tx:attributes>      </tx:advice>      <!-- Spring aop事務(wù)管理 -->      <aop:config>          <aop:pointcut id="transactionPointcut"              expression="execution(* org.andy.shop.service..*Impl.*(..))" />          <aop:advisor pointcut-ref="transactionPointcut"              advice-ref="transactionAdvice" />      </aop:config>    </beans>  主要配置數(shù)據(jù)連接池，事務(wù)管理，%20mybatis關(guān)聯(lián)映射等，事務(wù)采用aop的聲明式事務(wù)。

6、引入日志

 %20  %20在src/main/resources中添加log4j日志配置信息：

  %20log4j.properties

[plain]%20view%20plain%20copy%20### set log levels ###  log4j.rootLogger = INFO , C , D , E     ### console ###  log4j.appender.C = org.apache.log4j.ConsoleAppender  log4j.appender.C.Target = System.out  log4j.appender.C.layout = org.apache.log4j.PatternLayout  log4j.appender.C.layout.ConversionPattern = [springmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n    ### log file ###  log4j.appender.D = org.apache.log4j.DailyRollingFileAppender  log4j.appender.D.File = ../logs/springmvc-mybatis-demo.log  log4j.appender.D.Append = true  log4j.appender.D.Threshold = INFO   log4j.appender.D.layout = org.apache.log4j.PatternLayout  log4j.appender.D.layout.ConversionPattern = [springmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n    ### exception ###  log4j.appender.E = org.apache.log4j.DailyRollingFileAppender  log4j.appender.E.File = ../logs/springmvc-mybatis-demo_error.log   log4j.appender.E.Append = true  log4j.appender.E.Threshold = ERROR   log4j.appender.E.layout = org.apache.log4j.PatternLayout  log4j.appender.E.layout.ConversionPattern = [sspringmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n  

7、創(chuàng)建Service

   %20在src/main/java中創(chuàng)建相關(guān)的org.andy.shop.service包和org.andy.shop.service.Impl包。

   %20UserService接口：

 %20

[java]%20view%20plain%20copy%20package org.andy.shop.service;    import java.util.List;    import org.andy.shop.model.UserInfo;    /**    * 創(chuàng)建時間：2015-1-27 下午5:15:03    * @author andy    * @version 2.2    */    public interface UserService {        UserInfo getUserById(int id);            List<UserInfo> getUsers();            int insert(UserInfo userInfo);  }    %20UserServiceImpl實現(xiàn)Service：[java]%20view%20plain%20copy%20package org.andy.shop.service.impl;    import java.util.List;    import org.andy.shop.dao.UserInfoMapper;  import org.andy.shop.model.UserInfo;  import org.andy.shop.service.UserService;  import org.springframework.beans.factory.annotation.Autowired;  import org.springframework.stereotype.Service;    /**  * 創(chuàng)建時間：2015-1-27 下午5:22:59  *   * @author andy  * @version 2.2  */  @Service("userService")  public class UserServiceImpl implements UserService {        @Autowired      private UserInfoMapper userInfoMapper;        @Override      public UserInfo getUserById(int id) {          return userInfoMapper.selectByPrimaryKey(id);      }        @Override      public List<UserInfo> getUsers() {          return userInfoMapper.selectAll();      }        @Override      public int insert(UserInfo userInfo) {                    int result = userInfoMapper.insert(userInfo);                    System.out.println(result);          return result;      }    }  

8、測試Spring和Mybatis配置

  %20在src/test/java中寫測試類，檢測是否能夠讀出數(shù)據(jù)，若能讀出則證明Spring+Mybatis整合成功。

TestUserService測試類：

[java]%20view%20plain%20copy%20package org.andy.shop.service;    import java.util.List;    import org.andy.shop.model.UserInfo;  import org.apache.log4j.Logger;  import org.junit.Test;  import org.junit.runner.RunWith;  import org.springframework.beans.factory.annotation.Autowired;  import org.springframework.test.context.ContextConfiguration;  import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;    import com.alibaba.fastjson.JSON;    /**  * 創(chuàng)建時間：2015-1-27 下午10:45:38  *   * @author andy  * @version 2.2  */  @RunWith(SpringJUnit4ClassRunner.class)  @ContextConfiguration(locations = { "classpath:spring.xml",          "classpath:spring-mybatis.xml" })  public class TestUserService {        private static final Logger LOGGER = Logger              .getLogger(TestUserService.class);        @Autowired      private UserService userService;              @Test      public void testQueryById1() {          UserInfo userInfo = userService.getUserById(1);          LOGGER.info(JSON.toJSON(userInfo));      }        @Test      public void testQueryAll() {          List<UserInfo> userInfos = userService.getUsers();          LOGGER.info(JSON.toJSON(userInfos));      }        @Test      public void testInsert() {          UserInfo userInfo = new UserInfo();          userInfo.setUname("xiaoming");          userInfo.setUnumber(4);          int result = userService.insert(userInfo);          System.out.println(result);      }  }  若是測試成功，那證明已經(jīng)成功了一半了。

9、引入SpringMVC

9.1%20配置SpringMVC配置信息

   %20SpringMVC的配置信息主要包括控制層Controller的bean管理，視圖層和控制層配置等等，下面是spring-mvc.xml信息：

 

[html]%20view%20plain%20copy%20<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"      xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"      xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-4.1.xsd           http://www.springframework.org/schema/context           http://www.springframework.org/schema/context/spring-context-4.1.xsd           http://www.springframework.org/schema/mvc           http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">        <!-- 自動掃描controller包下的所有類，如果@Controller注入為bean -->      <context:component-scan base-package="org.andy.shop.controller" />        <!-- 避免IE執(zhí)行Ajax時,返回JSON出現(xiàn)下載文件 -->      <bean id="mappingJacksonHttpMessageConverter"          class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">          <property name="supportedMediaTypes">              <list>                  <value>text/html;charset=UTF-8</value>              </list>          </property>      </bean>        <!-- 啟動Spring MVC的注解功能，完成請求和注解POJO的映射 -->      <bean          class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">          <property name="messageConverters">              <list>                  <!-- json轉(zhuǎn)換器 -->                  <ref bean="mappingJacksonHttpMessageConverter" />              </list>          </property>      </bean>        <!-- 對模型視圖名稱的解析，即在模型視圖名稱添加前后綴 -->      <bean          class="org.springframework.web.servlet.view.InternalResourceViewResolver">          <property name="viewClass"              value="org.springframework.web.servlet.view.JstlView" />          <property name="prefix" value="/WEB-INF/views" />          <property name="suffix" value=".jsp" />      </bean>        <!-- 配置多文件上傳 -->      <bean id="multipartResolver"          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">          <property name="defaultEncoding">              <value>UTF-8</value>          </property>          <property name="maxUploadSize">              <!-- 上傳文件大小限制為31M，31*1024*1024 -->              <value>32505856</value>          </property>          <property name="maxInMemorySize">              <value>4096</value>          </property>      </bean>    </beans>   %20自動掃描org.andy.shop.controller報下還有@Controller的控制層，注入為bean。

9.2、Web容器web.xml配置

   %20web容器配置啟動加載的配置文件，設(shè)置SpringMVC攔截的請求（此處攔截.htmls結(jié)尾的url請求）

[html]%20view%20plain%20copy%20<?xml version="1.0" encoding="UTF-8"?>  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"      id="WebApp_ID" version="2.5">        <display-name>springmvc_mybatis_demo</display-name>        <context-param>          <param-name>contextConfigLocation</param-name>          <param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value>      </context-param>        <filter>          <filter-name>encodingFilter</filter-name>          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>          <init-param>              <param-name>encoding</param-name>              <param-value>utf-8</param-value>          </init-param>          <init-param>              <param-name>forceEncoding</param-name>              <param-value>true</param-value>          </init-param>      </filter>      <filter-mapping>          <filter-name>encodingFilter</filter-name>          <url-pattern>/*</url-pattern>      </filter-mapping>        <listener>          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>      </listener>        <!-- 防止spring內(nèi)存溢出監(jiān)聽器 -->      <listener>          <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>      </listener>        <servlet>          <description>spring mvc servlet</description>          <servlet-name>rest</servlet-name>          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>          <init-param>              <param-name>contextConfigLocation</param-name>              <param-value>                  classpath:spring-mvc.xml              </param-value>          </init-param>          <load-on-startup>1</load-on-startup>      </servlet>      <servlet-mapping>          <servlet-name>rest</servlet-name>          <url-pattern>*.htmls</url-pattern>      </servlet-mapping>        <!-- 配置session超時時間，單位分鐘 -->      <session-config>          <session-timeout>30</session-timeout>      </session-config>        <welcome-file-list>          <welcome-file>index.jsp</welcome-file>      </welcome-file-list>  </web-app>  

9.3、Controller控制層

   %20在org.andy.shop.controller創(chuàng)建控制層，如UserController.java

 %20

[java]%20view%20plain%20copy%20package org.andy.shop.controller;    import java.util.List;    import org.andy.shop.model.UserInfo;  import org.andy.shop.service.UserService;  import org.springframework.beans.factory.annotation.Autowired;  import org.springframework.stereotype.Controller;  import org.springframework.ui.ModelMap;  import org.springframework.web.bind.annotation.PathVariable;  import org.springframework.web.bind.annotation.RequestMapping;  import org.springframework.web.bind.annotation.ResponseBody;    /**    * 創(chuàng)建時間：2015-1-28 下午1:17:27    * @author andy    * @version 2.2    */  @Controller  @RequestMapping("/user")  public class UserController {        @Autowired      private UserService userService;            @RequestMapping("/showInfo/{userId}")      public String showUserInfo(ModelMap modelMap, @PathVariable int userId){          UserInfo userInfo = userService.getUserById(userId);          modelMap.addAttribute("userInfo", userInfo);          return "/user/showInfo";      }            @RequestMapping("/showInfos")      public @ResponseBody Object showUserInfos(){          List<UserInfo> userInfos = userService.getUsers();          return userInfos;      }  }  

9.4、視圖層

 %20在WEB-INF創(chuàng)建視圖總目錄views(為了安全起見一般都在WEB-INF下創(chuàng)建)，創(chuàng)建/user/showInfo.jsp視圖文件。

 %20

[html]%20view%20plain%20copy%20<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">  <html>  <head>  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  <title>userInfo</title>  </head>  <body>         姓名： ${userInfo.uname}    </body>  </html>  

9.5、項目總目錄結(jié)構(gòu)

  %20到此為demo以及基本創(chuàng)建完成總目錄如下：

    %20

10、項目測試

    將項目編譯，Maven build...輸入clean compile package，部署到Tomcat服務(wù)器，啟動項目。

   測試1：測試第一個url，  http://localhost:8080/springmvc_mybatis_demo/user/showInfo/1.htmls

    

   測試2：測試第二個json數(shù)據(jù)返回的url，  http://localhost:8080/springmvc_mybatis_demo/user/showInfos.htmls

   

ok，數(shù)據(jù)正常顯示，SpringMVC+Mybatis搭建成功。

后續(xù)

    在測試時，我們并不需要要啟動web容器，junit測試時，需要以下幾點注意事項：

   1、測試時，將pom.xml文件中的依賴包的范圍去掉

         junit，spring-test，servlet-api的scope范圍去掉。

    2、在測試編譯時，可能會把mybatis的映射配置文件.xml過濾掉，所以需要在pom.xml中添加如下配置：

       

[html] view plain copy 在CODE上查看代碼片<resources>      <resource>          <directory>src/main/resources</directory>          <includes>              <include>**/*.properties</include>              <include>**/*.xml</include>          </includes>          <filtering>true</filtering>      </resource>      <resource>          <directory>src/main/java</directory>          <includes>              <include>**/*.xml</include>          </includes>          <filtering>true</filtering>      </resource>  </resources>  

  %20上述文件添加在<build></build>節(jié)點中。

 %20 3、項目導(dǎo)入注意事項

 %20 %20 下載完之后，只保留pom.xml%20和%20src兩個文件，其他的刪除。

       

        右擊“Import..” 選擇maven項目導(dǎo)入（所以首先要將maven插件裝好，maven配好），如下：

     

         導(dǎo)入以后項目會出現(xiàn)叉號，項目是在jdk1.7基礎(chǔ)上運行的，需要配置一下項目的環(huán)境（jdk裝1.7及以上），右擊該項目選擇“Properties”彈出如下框：

      上述三場需要修改：

           1、JavaBuild Path 選“Libraries”，將JRE System Library改為安裝的javase-1.7

           2、Java Compile 中的JDK Compliance 中Compiler Compliance level 改為 1.7

           3、Project Facets 中 將Dynamic Web Module 改為2.5及以上

                                                     Java中的版本改為 1.7
