由于剛剛開始學習sPRing，對于他的理解也不是非常的透徹，從我個人的角度來說，能夠使用他進行mvc開發就已經足夠了。

目標：能夠把spring框架集成到開發環境中。

工具：eclipse + spring2.5.6

步驟：1、下載eclipse 或者是myeclipse 根據個人喜好從網上下載。

         2、下載spring2.5.6(目前最高版本是3.0) 到spring官方網站下載 http://www.springsource.org/download 。注意：下載前

               需要填寫個人資料。要下載spring-framework-2.5.6-with-dependencies版本

         3、解壓spring。spring要運行必須需要兩個jar文件

              spring.jar(dist目錄下面)

              commons-logging.jar(lib/jakarta-commons目錄下面)

         4、接下來就是使用eclipse建立一個工程(java 或者 web工程都可以)

         5、把上面的兩個jar文件添加進入工程中。

         6、測試是否集成成功

               view plaincopy to clipboardprint?
package my.sh.spring;

import org.springframework.context.applicationContext;
import org.springframework.context.support.ClassPathxmlApplicationContext;

public class springtest {

    public static void main(String[] args) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
    }

}
package my.sh.spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class springtest {

public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
}

}

               觀察控制臺輸出

              正確輸出：

              view plaincopy to clipboardprint?

             如果你沒有引用 commons-logging.jar ，會輸出如下錯誤提示

             view plaincopy to clipboardprint?
