Hibernate【4】——与Struts2整合

1、整体目录

struts负责响应前台页面的动作；

hibernate负责后台链接数据库的操作；

（1）添加struts包到lib

（2）添加struts的xml配置文件

（3）添加Action类

2、struts的xml

只需要写<action>标签之间的东西

23         <action name="login" class="com.demo.struts.action.UserAction" method="login">
24             <result name="success">/success.jsp</result>
25             <result name="error">/index.jsp</result>
26         </action>
name和index页面中的action的name一样，class表示使用那个action类来响应，method表示使用action类中的哪个方法
result的name表示method返回的值，/success.jsp表示对应result跳转的页面

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

            <result name="regsucc">/regsucc.jsp</result>
        </action>
    </package>


    <!-- Add packages here -->

</struts>

3、Action类

关于数据库的操作，只要调用service层的类就好了~

package com.demo.struts.action;

import com.demo.model.User;
import com.demo.service.UserService;
import com.demo.service.UserServiceImpl;
import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {
    private User user;
    private String confirmPwd;
    private String message;
    private UserService userService = new UserServiceImpl();
    
    /**
     * 用户登录
     * @return
     */
    public String login(){
        String name = user.getUserName();
        String pwd = user.getUserPwd();
        if(userService.login(name, pwd)!=null){
            message ="登录成功！";
            return "success";
        }else{
            message = "用户名或者密码错误！";
            return "error";
        }
    }
    /**
     * 跳转注册页面
     * @return
     */
    public String register(){
        return "register";
    }
    
    /**
     * 用户注册 
     * @return
     */
    public String register2(){
        String name=user.getUserName();
        String pwd = user.getUserPwd();
        if(userService.isExist(name, pwd) == true){
            return "register";
        }else{
            userService.add(user);
            return "regsucc";
        }
    }
    

    
    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getConfirmPwd() {
        return confirmPwd;
    }

    public void setConfirmPwd(String confirmPwd) {
        this.confirmPwd = confirmPwd;
    }
    
}
