Struts2+Spring+Hibernate 筹建全解

Struts2+Spring+Hibernate 搭建全解！
Struts2+Spring+Hibernate 搭建全解！

Struts2+Spring+Hibernate是J2EE的最新流行框架。本篇是我搭建这个框架的经验总结，有很多人搭建这个框架总会遇到

大大小小的问题，网上也没有什么行之有效的方案或成体系的介绍，所以我就决定总结一下我的搭建过程。给一些搭

建尚存问题的朋友提供帮助。

我用这个框架，实现的是基本的CRUD功能的一个雇员管理系统，本来打算丰富一下功能，但是一直没能抽出空去搞。

目前版本暂定为1.0，除了CRUD外还配置了表单验证框架JSValidation。功能都能很顺利的实现。

现在分享部分源码，来说明一些注意事项。

以下是部分搭建过程及源码：

1.先组合实现Hibernate3.2+Spring2.5支持，删除hibernate.cfg.xml文件，修改 applicationContext.xml文件的内容，增加SessionFactory和dataSource的设置。

2.通过MyEclipse的向导方式，生成POJO类和对应的映射文件。

3.修改applicationContext.xml文件中<property name="mappingResources">元素的内容。

4.编写DAO接口和实现类。

5.修改applicationContext.xml文件，增加对Dao实现类的配置。

6.组合Struts2和Spring2.5，修改web.xml文件，增加struts2的所需要的过滤器配置。

7.增加struts2相应类库，增加struts2与spring的配置jar包。

8.拷贝struts.xml文件到src根目录下，再修改struts.xml文件，进行常量配置。

9.修改web.xml文件，配置Spring监听器，和上下文变量。并增加OpenSessionInViewFilter的设置。

10.写入action类。

11.配置struts.xml文件。

12.修改applicationContext.xml

13.编写Jsp文件。

14.加载运行项目。

下面是关键文件的源码：
