Struts2&＃43;Spring&＃43;Hibernate搭建全解&＃xff01;
Struts2&＃43;Spring&＃43;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&＃xff0c;有很多人搭建这个框架总会遇到
大大小小的问题&＃xff0c;网上也没有什么行之有效的方案或成体系的介绍&＃xff0c;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&＃xff0c;实现的是基本的CRUD功能的一个雇员管理系统&＃xff0c;本来打算丰富一下功能&＃xff0c;但是一直没能抽出空去搞。
目前版本暂定为1.0&＃xff0c;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&＃xff0c;来说明一些注意事项。
以下是部分搭建过程及源码&＃xff1a;
1.先组合实现Hibernate3.2&＃43;Spring2.5支持&＃xff0c;删除hibernate.cfg.xml文件&＃xff0c;修改applicationContext.xml文件的内容&＃xff0c;增加SessionFactory和dataSource的设置。
2.通过MyEclipse的向导方式&＃xff0c;生成POJO类和对应的映射文件。
3.修改applicationContext.xml文件中
4.编写DAO接口和实现类。
5.修改applicationContext.xml文件&＃xff0c;增加对Dao实现类的配置。
6.组合Struts2和Spring2.5&＃xff0c;修改web.xml文件&＃xff0c;增加struts2的所需要的过滤器配置。
7.增加struts2相应类库&＃xff0c;增加struts2与spring的配置jar包。
8.拷贝struts.xml文件到src根目录下&＃xff0c;再修改struts.xml文件&＃xff0c;进行常量配置。
9.修改web.xml文件&＃xff0c;配置Spring监听器&＃xff0c;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。
