修改成功

关键代码如下

基层的代码,这里增加了一个根据用户id查询的方法

dao层

//修改                public USer modify( int user_id,USer user)                {                    init() ;                                        //获取对象                    USer us = (USer)se.get(USer.class, user_id) ;                                        us.setBrithday(user.getBrithday());                    us.setMoney(user.getMoney());                    us.setName(user.getName());                    us.setPassword(user.getPassword());                    us.setUser_id(user.getUser_id());                                                            //se.saveOrUpdate(us);                                         destory();                                        return us;                  }                //查询单个                public USer selectu( int user_id)                {                    init() ;                                        //获取对象                    USer us = (USer)se.get(USer.class, user_id) ;                                        destory();                                        return us;                  }

用户列表页面   ,点击修改通过Action(如果页面在webcotent下可不用Action)跳转到修改页面

<%@page import="com.hanqi.utility.USer"%><%@page import="java.util.List"%><%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><%List<USer> list = (List<USer>)request.getAttribute("selectuser") ;for(USer us : list ){    out.print(us + "<a href=‘deleteuser?user_id="+us.getUser_id()+"‘>    【删除】</a>"                        +"<a href=‘modify?userid="+us.getUser_id()+"‘>    【修改】</a>"                            +"<br>") ;}%></body></html>

修改页面代码如下,点击提交进入Action并调用Action类的方法执行操作

 1 <%@page import="com.hanqi.service.UserService"%> 2 <%@page import="com.hanqi.utility.USer"%> 3 <%@ page language="java" contentType="text/html; charset=UTF-8" 4     pageEncoding="UTF-8"%> 5 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 6 <html> 7 <head> 8 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 9 <title>Insert title here</title>10 </head>11 <body>12 <%13 int user_id = Integer.parseInt(request.getAttribute("lll").toString());14 15 USer us = new UserService().hah(user_id) ;16 //out.print(us) ;17 %>18 <form action="modifyuser.action" method="post">19 id<input type="text"  value="<%out.print(user_id) ;%>"name="us.user_id" readonly><br><br>20 姓名<input type="text" name="us.name" value="<%out.print(us.getName()) ;%>"><br><br>21 密码<input type="password" name="us.password" value="<%out.print(us.getPassword()) ;%>"><br><br>22 生日<input type="text" name="us.brithday" value="<%out.print(us.getBrithday()) ;%>"><br><br>23 薪酬<input type="text" name="us.money" value="<%out.print(us.getMoney()) ;%>"><br><br>24 <input type="submit" value="提交" ><br>25 </body>26 </html>

Action类关键代码如下

 1 //修改用户 2     public String modifyuser() 3     { 4         String rtn = "fail" ; 5          6         try 7         { 8             //获取user_id 9             //得到原生request10             HttpServletRequest hsr = ServletActionContext.getRequest() ;11             12             String userid = hsr.getParameter("us.user_id") ;13             14             System.out.println(userid);15             16             int user_id = Integer.parseInt(userid) ;17             18             new UserService().modify(user_id, us); ;19             20             rtn = "success" ;21             22         }catch(Exception e)23         {24             e.printStackTrace();25         }26         27         return rtn;28     }29     30     //查询单个31     public String selectu()32     {33         String rtn = "fail" ;34         35         try36         {37             //获取user_id38             //得到原生request39             HttpServletRequest hsr = ServletActionContext.getRequest() ;40             41             String useid = hsr.getParameter("userid") ;42             43             int user_id = Integer.parseInt(useid) ;44             45             /*46              * 将从用户列表页面获取的id 放入request47              * 目的:为了在修改页面获取当前行的用户id48              */49             hsr.setAttribute("lll", user_id); 50             51             //执行删除52             new UserService().hah(user_id);53             54             rtn = "success" ;55             56         }catch(Exception e)57         {58             e.printStackTrace();59         }60         61         return rtn;62     }

Struts的配置代码如下:

 1 <!-- 修改 --> 2     <action name="modifyuser" class="com.hanqi.action.USerAction" method="modifyuser"> 3      4             <result name="fail">/WEB-INF/pages/fail.jsp</result> 5          6             <result name="success" type="redirectAction">selectUSer</result> 7      8     </action> 9     10     <!-- 查询单个 -->11     <action name="modify" class="com.hanqi.action.USerAction" method="selectu">12     13             <result>/WEB-INF/pages/modify.jsp</result>14     15     </action>

 此时完成
