核心提示:由于刚刚开始学习sPRing,对于他的理解也不是非常的透彻,spring 框架使用初步,从我个人的角度来说,能够使用他进行mvc开发就已经足够了,spring要运行必须需要两个jar文件spring.jar(dist目录下面)commons-logging.jar(lib\jakarta-commons目录下面) 4、
由于刚刚开始学习sPRing,对于他的理解也不是非常的透彻,从我个人的角度来说,能够使用他进行mvc开发就已经足够了。

目标:能够把spring框架集成到开发环境中。

工具:eclipse + spring2.5.6

步骤:1、下载eclipse 或者是myeclipse 根据个人喜好从网上下载。

     2、下载spring2.5.6(目前最高版本是3.0) 到spring官方网站下载 http://www.springsource.org/download 。注意:下载前

        需要填写个人资料。要下载spring-framework-2.5.6-with-dependencies版本

     3、解压spring。spring要运行必须需要两个jar文件

       spring.jar(dist目录下面)

       commons-logging.jar(lib\jakarta-commons目录下面)

     4、接下来就是使用eclipse建立一个工程(java 或者 web工程都可以)

     5、把上面的两个jar文件添加进入工程中。

     6、测试是否集成成功

        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");
}

}

        观察控制台输出

       正确输出:

       view plaincopy to clipboardprint?

       如果你没有引用 commons-logging.jar ,会输出如下错误提示

       view plaincopy to clipboardprint?
