最新版Struts2+Hibernate+Spring整合
目前为止三大框架最新版本是：
struts2.3.16.1
hibernate4.3.4
spring4.0.2
其中struts2和hibernate的下载方式比较简单，但是spring下载有点麻烦，可以直接复制下面链接下载最新版spring
http://repo.springsource.org/libs-release-local/org/springframework/spring/4.0.2.RELEASE/spring-framework-4.0.2.RELEASE-dist.zip
一. 所需的jar包（其中aopaliance-1.0.jar，是spring所依赖的jar，直接复制粘贴到谷歌百度就有的下载）

CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_name` varchar(20) DEFAULT NULL,
`password` varchar(20) DEFAULT NULL,
`address` varchar(100) DEFAULT NULL,
`phone_number` varchar(20) DEFAULT NULL,
`create_time` datetime DEFAULT NULL,
`update_time` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULTCHARSET=utf8;
并插入一条数据INSERT INTO `user` VALUES ('1', 'test','test', 'test', 'test', '2014-03-29 00:48:14', '2014-03-29 00:48:17');
三. 先看下myeclipse的目录结构
四. 配置文件

<!-- 当hibernate+spring配合使用的时候，如果设置了lazy=true,那么在读取数据的时候，当读取了父数据后，
hibernate会自动关闭session，这样，当要使用子数据的时候，系统会抛出lazyinit的错误，
这时就需要使用spring提供的 OpenSessionInViewFilter,OpenSessionInViewFilter主要是保持Session状态
知道request将全部页面发送到客户端，这样就可以解决延迟加载带来的问题 -->
