使用IDEA和gradle搭建SPRing MVC和MyBatis開(kāi)發(fā)環(huán)境

1. 概述

Gradle是一個(gè)基于Apache Ant和Apache Maven概念的項(xiàng)目自動(dòng)化建構(gòu)工具。它使用一種基于Groovy的特定領(lǐng)域語(yǔ)言(DSL)來(lái)聲明項(xiàng)目設(shè)置，拋棄了基于xml的各種繁瑣配置。

Spring MVC屬于SpringFrameWork的后續(xù)產(chǎn)品，已經(jīng)融合在Spring Web Flow里面。Spring 框架提供了構(gòu)建 Web 應(yīng)用程序的全功能 MVC 模塊。

MyBatis本是apache的一個(gè)開(kāi)源項(xiàng)目iBatis, 2010年這個(gè)項(xiàng)目由apache software foundation 遷移到了google code，并且改名為MyBatis 。 2013年11月遷移到Github。

2. 準(zhǔn)備工作

1.安裝MySQL，并完成相應(yīng)數(shù)據(jù)庫(kù)的建立

2.安裝IDEA完整版

3.下載tomcat或其他服務(wù)器

3. 創(chuàng)建工程

打開(kāi)IDEA軟件，選擇Create New Project：

選擇創(chuàng)建基于gradle的java web項(xiàng)目：

輸入GroupId和ArtifactId：

選擇gradle的來(lái)源，可以用自己下載的gradle，也可以使用IDEA內(nèi)建的gradle版本：

選擇項(xiàng)目的目錄：

點(diǎn)擊完成，會(huì)生成一個(gè)最基本的java web目錄，增加文件夾和相應(yīng)文件，將其目錄結(jié)構(gòu)改為以下結(jié)構(gòu)：

其中resources目錄中的config文件夾中的文件和WEB-INF文件夾下的web.xml，以及build.gradle都是自己進(jìn)行配置的。

配置文件

1. generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration> <classPathEntry location="${jarDirection}"/> <context id="mysql" targetRuntime="MyBatis3"> <jdbcConnection driverClass="${driverClass}" connectionURL="${connectionURL}" userId="${userId}" passWord="${password}"> </jdbcConnection> <javaTypeResolver > <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <javaModelGenerator targetPackage="${modelPackage}" targetProject="${src_main_java}"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <sqlMapGenerator targetPackage="${sqlMapperPackage}" targetProject="${src_main_java}"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <javaClientGenerator type="XMLMAPPER" targetPackage="${mapperPackage}" targetProject="${src_main_java}"> <property name="enableSubPackages" value="true" /> </javaClientGenerator>  <table schema="test" tableName="user" domainObjectName="User" >  </table> </context></generatorConfiguration>

2. gradle.properties

# 生成的model類(lèi)所在包modelPackage=cn.edu.bupt.wen.model# 生成的mapper接口類(lèi)所在包mapperPackage=cn.edu.bupt.wen.mapper# 生成的mapper xml文件所在包sqlMapperPackage=cn.edu.bupt.wen.mybatis_mapper

3. jdbc-mysql.properties

# 將jdbc.jarDirection后的內(nèi)容更改為gradle下載的# mysql-connector-java-5.1.x.jar所在的路徑，gradle自動(dòng)下載的路徑如下所示jdbc.jarDirection=/Users/wenzhiquan/.gradle/caches/modules-2/files-2.1/mysql/mysql-connector-java/5.1.38/dbbd7cd309ce167ec8367de4e41c63c2c8593cc5/mysql-connector-java-5.1.38.jarjdbc.driverClassName=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/bookbestjdbc.user=rootjdbc.pass=root

4. spring-mvc.xml

<?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" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">  <context:component-scan base-package="cn.edu.bupt.wen"/>  <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean>  <mvc:annotation-driven></mvc:annotation-driven>  <mvc:resources mapping="/statics/**" location="/WEB-INF/statics/" /></beans>

5. web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <servlet> <servlet-name>index-dispather</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:config/spring/spring-mvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>index-dispather</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping></web-app>

6. build.gradle

group 'cn.edu.bupt.wen'version '1.0-SNAPSHOT'apply plugin: 'groovy'apply plugin: 'java'apply plugin: 'war'apply plugin: 'idea'sourceCompatibility = 1.5repositories { mavenCentral()}configurations { mybatisGenerator}// 讀取config文件夾中對(duì)應(yīng)的配置文件ext{ def prop = new Properties(); file("src/main/resources/config/mybatis/jdbc-mysql.properties") .withInputStream { prop.load(it) } file("src/main/resources/config/mybatis/gradle.properties") .withInputStream { prop.load(it) } prop.each { project.extensions.add("$it.key",it.value); }}// 配置gradle的依賴(lài)項(xiàng)dependencies { compile 'org.codehaus.groovy:groovy-all:2.3.11' compile 'jstl:jstl:1.2' compile 'org.springframework:spring-aop:4.2.4.RELEASE' compile 'org.springframework:spring-context:4.2.4.RELEASE' compile 'org.springframework:spring-beans:4.2.4.RELEASE' compile 'org.springframework:spring-web:4.2.4.RELEASE' compile 'org.springframework:spring-webmvc:4.2.4.RELEASE' compile 'org.springframework:spring-tx:4.2.4.RELEASE' compile 'org.springframework:spring-jdbc:4.2.4.RELEASE' compile 'org.springframework:spring-test:4.2.4.RELEASE' compile 'mysql:mysql-connector-java:5.1.38' compile 'org.mybatis.generator:mybatis-generator-core:1.3.2' compile 'org.mybatis:mybatis-spring:1.2.3' compile 'org.mybatis:mybatis:3.3.0' compile 'junit:junit:4.12' mybatisGenerator 'org.mybatis.generator:mybatis-generator-core:1.3.2' mybatisGenerator 'mysql:mysql-connector-java:5.1.38' testCompile group: 'junit', name: 'junit', version: '4.11'}// 利用ant創(chuàng)建一個(gè)自動(dòng)生成MyBatis目錄文件的tasktask mybatisGenerate << { ant.properties['targetProject'] = projectDir.path ant.properties['jarDirection'] = project['jdbc.jarDirection'] ant.properties['driverClass'] = project['jdbc.driverClassName'] ant.properties['connectionURL'] = project['jdbc.url'] ant.properties['userId'] = project['jdbc.user'] ant.properties['password'] = project['jdbc.pass'] ant.properties['src_main_java'] = sourceSets.main.java.srcDirs[0].path ant.properties['src_main_resources'] = sourceSets.main.resources.srcDirs[0].path ant.properties['modelPackage'] = project['modelPackage'] ant.properties['mapperPackage'] = project['mapperPackage'] ant.properties['sqlMapperPackage'] = project['sqlMapperPackage'] ant.taskdef( name: 'mbgenerator', classname: 'org.mybatis.generator.ant.GeneratorAntTask', classpath: configurations.mybatisGenerator.aspath ) ant.mbgenerator(overwrite: true, configfile: 'src/main/resources/config/mybatis/generatorConfig.xml', verbose: true) { propertyset { propertyref(name: 'targetProject') propertyref(name: 'jarDirection') propertyref(name: 'userId') propertyref(name: 'driverClass') propertyref(name: 'connectionURL') propertyref(name: 'password') propertyref(name: 'src_main_java') propertyref(name: 'src_main_resources') propertyref(name: 'modelPackage') propertyref(name: 'mapperPackage') propertyref(name: 'sqlMapperPackage') } }}

下載gradle依賴(lài)包

至此，基本的配置就完成了，接下來(lái)就需要運(yùn)行g(shù)radle下載相應(yīng)的依賴(lài)包了，操作如下：打開(kāi)IDEA > View > Tool Windows > gradle:

點(diǎn)擊圖中的按鈕，IDEA就會(huì)自動(dòng)下載依賴(lài)包了。

下載完成后，目錄下的External Libraries文件夾會(huì)生成相應(yīng)的目錄：

下載完依賴(lài)包之后，整體的配置基本上就完成了。

3. 部署到Tomcat服務(wù)器

打開(kāi)IDEA > Run > Edit Configurations...

點(diǎn)擊tomcat server的local選項(xiàng)，點(diǎn)擊右上角的configure...，在彈出的對(duì)話框中選中下載的Tomcat根目錄：

然后將配置好的tomcat添加到運(yùn)行庫(kù)當(dāng)中：

4. 編寫(xiě)代碼并運(yùn)行

編寫(xiě)controller代碼

在controller文件夾中創(chuàng)建IndexController文件，將代碼修改為：

package cn.edu.bupt.wen.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;/** * Author wenzhiquan * Created on 16/4/12 下午12:25 * File name: IndexController.java * Description: null */@Controllerpublic class IndexController { @RequestMapping("/") public String index(){ return "index"; }}

修改index.jsp

將index.jsp文件修改為自己想要的樣式：

<%-- Created by IntelliJ IDEA. User: wenzhiquan Date: 16/4/12 Time: 下午12:23 To change this template use File | Settings | File Templates.--%><%@ page contentType="text/html;charset=UTF-8" language="java" %><html> <head> <title>Index</title> </head> <body> Hello World! </body></html>
