Struts2.3.16.1+Hibernate4.3.4+Spring4.0.2 框架整合

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）

框架	版本	所需jar包
Struts2	2.3.16.1
Hibernate	4.3.4
spring	4.0.2
其它	无

二.  创建一张表

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
