spring整合ssmXML版

以下是一个简单的ssm项目：如果中途报错，肯定是tomcat配置或者数据库配置有问题，在程序中注意将包名等配置换成自己的。数据库表需要提前建好，并加入数据，注意表结构要和实体对象对应。

1.开发条件：eclipse + comcat7.0

2.创建一个Dynamic Web Project项目，大概的目录结构。

3.jar包如下：

4.页面访问结果：http://localhost:8080/spring001/list.action

下面开始上代码：

    }

    public UserDao getUserDao() {

        return userDao;
