2014-11-11 16:11 711 查看

本文提供Struts2整合Spring Hibernate的CRUD的实例的源代码

1. 数据库脚本，数据库采用MySQL 5.0

CREATE TABLE `user` (

`id` int(11) NOT NULL auto_increment,

`username` varchar(32) NOT NULL,

`password` varchar(32) NOT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. 几个重要的文件

web.xml

<?xml version="1.0" encoding="UTF-8"?>
