[待解决问题]

输入地址http://localhost:8080/Contact/contact/login_form.do,跳到登陆界面

1 @RequestMapping(value = "/login_form.do")
2     public String getLoginForm(Model model) {
3         logger.info("getRegForm method invoked");
4         model.addAttribute("contact", new Contact());
5         return "loginform";
6     }

 

 

输入账号密码进行登陆,可成功登陆

1 @RequestMapping(value = "/login.do")
2     public String login(@ModelAttribute Contact contact, Model model) {
3         logger.info("login method invoked and receive the param :" + JSON.toJSONString(contact));
4         contact = contactService.login(contact.getName(), contact.getPassword());
5         logger.info(JSON.toJSONStringWithDateFormat(contact, "yyyy-MM-dd"));
6         model.addAttribute("contact", contact);
7         return "personalMsg";
8     }

 

 

一下是登陆后跳转到的personalMsg.jsp

 1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 <html>
 5 <head>
 6 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 7 <title>Insert title here</title>
 8 </head>
 9 <body>
10     personalMsg
11     <br>
12 
13     <br>
14 
15     <a href="update_form/${contact.id }.do">${contact.name }</a>
16 
17 </body>
18 </html>

 

 

点击a标签,调用修改表单,这里也没有问题

1 @RequestMapping(value = "/update_form/{id}")
2     public String getUpdateForm(@PathVariable int id, Model model) {
3         logger.info("getContact method invoked and receive param :");
4         Contact contact = contactService.getContactById(id);
5         logger.info("contact:" + JSON.toJSONStringWithDateFormat(contact, "yyyy-MM-dd"));
6         model.addAttribute("contact", contact);
7         return "updateform";
8     }

 

 

 

更改完数据,点击修改调用,这里开始报错

 1 @RequestMapping(value = "/update")
 2     public String update(@ModelAttribute @Valid Contact contact, BindingResult bindingResult, Model model) {
 3         logger.info("update method invoked and receive the param :"
 4                 + JSON.toJSONStringWithDateFormat(contact, "yyyy-MM-dd"));
 5         if (bindingResult.hasErrors()) {
 6             return "updateform";
 7         }
 8         contact = contactService.getContactById(contact.getId());
 9         model.addAttribute("contact",contact);
10         return "personalMsg";
11     }
