問題描述

這是我的代碼： 

register.jsp

<body>
 <div> 
 <h3>Register</h3> 
 <form:form method="post" action="insert" modelAttribute="user">  
 <table>  
 <tr>  
  <td>User Name :</td>  
  <td><form:input path="uName" /></td>  
 </tr>  
 <tr>  
  <td>Password :</td>  
  <td><form:input path="password" /></td>  
 </tr>  
 <tr>  
  <td> </td>  
  <td><input type="submit" value="Save" /></td>  
 </tr>  
 </table>
 </form:form>
 </div>
 <div>  
 <h3>Login</h3>
 <form:form method="post" action="login" modelAttribute="user">  
 <table>  
 <tr>  
  <td>User Name :</td>  
  <td><form:input path="uName" /></td>  
 </tr>  
 <tr>  
  <td>Password :</td>  
  <td><form:input path="password" /></td>  
 </tr>  
 <tr>  
  <td> </td>  
  <td><input type="submit" value="Submit" /></td>  
 </tr>  
 </table>
 </form:form>
 </div>

 </body>

HomePageController.java 

@Controller
public class HomePageController {

@Autowired
UserDaoImpl userDaoImpl;
@RequestMapping("/register")
public ModelAndView registerUser(@ModelAttribute user use){
    return new ModelAndView("register");

}
@RequestMapping("/insert")
public ModelAndView successMessage(@ModelAttribute user use){
    if(use != null){
        userDaoImpl.insertData(use);
    }
    return new ModelAndView("success" ,"name", use.getuName());
}
@RequestMapping("/login")
public ModelAndView getUserList(@ModelAttribute user u){
    List<user> userList = userDaoImpl.getData();
    int len = userList.size();
    for(int i = 0;i<= len ; i++){
        String userr = userList.get(i).getuName();
        if(userr.equals(u.getuName())){
            return new ModelAndView("quiz","name", u.getuName());
        }
    }
    return new ModelAndView("register");
}
@RequestMapping("/userSign")
public ModelAndView getUser(String name){

    List<user> userList = userDaoImpl.getData();
    int len = userList.size();
    for(int i = 0;i<= len ; i++){
        String userr = userList.get(i).getuName();
        if(userr.equals(name)){
            return new ModelAndView("quiz","name", name);
        }
    }
    return new ModelAndView("error","name",name);
 }
}

在登錄表單中，如果我輸入正確的用戶名和密碼，那么它將成功顯示quiz.jsp文件，但是如果我輸入了錯誤的用戶名和密碼，則它必須顯示error.jsp但不會顯示error 404: requested resource not found

同樣，我在quiz.jsp有一個鏈接，如果我單擊該鏈接，則它必須轉到play.jsp但這給了我錯誤，但找不到請求的資源

您的for循環中的范圍檢查錯誤。

它們都必須是'<'而不是'<='
