简单ssh注解模式搭建

项目目录结构如下：



引入jar包到WebContent----->WEB-INF----->lib下：



配置web.xml文件，在WEB-INF下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

</listener-class>
</listener>
</web-app>配置在WEB-INF下spring和hibernate的application.xml：

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

</beans>

配置在src下struts2的struts.xml：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<!-- 将对象交给spring管理 -->
<constant name="struts.objectFactory" value="spring" />
<!-- 指定资源编码类型 -->

}

配置UserDao.java持久层

* @return list<User> 集合
*/
@SuppressWarnings("unchecked")

session = sessionFactory.openSession();
String hql = "from User";
Query query = session.createQuery(hql);
return (List<User>)query.list();
}
/**

* @param user
* @return user
*/
public User loginUser(User user){
session = sessionFactory.openSession();
String hql = "from User where userName = ? and userPass = ?";
Query query = session.createQuery(hql);

}配置UserService.java业务逻辑层：



package com.aishang.service;

super();
}
//查询用户信息
public List<User> showUsers(){
return userdao.queryUsers();
}
//用户登陆
public User isLoginUser(User user){
return userdao.loginUser(user);
}

public UserDao getUserdao() {
return userdao;
}

public void setUserdao(UserDao userdao) {
this.userdao = userdao;
}

}配置UserAction.java控制层

package com.aishang.service;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.aishang.dao.UserDao;

}
//查询用户信息
public List<User> showUsers(){

}
//用户登陆
public User isLoginUser(User user){
return userdao.loginUser(user);
}

public UserDao getUserdao() {
return userdao;
}

public void setUserdao(UserDao userdao) {
this.userdao = userdao;
}

}编写测试页测试程序是否成功运行！
。。。。。。。配置完成！
