@RequestMapping在春天無法獲得第二控制器接管

Question

我有這個程序，我正在寫，我試圖讓用戶登錄後顯示第二頁。我的第一個屏幕處理通過LoginInterfaceController，如下所示。

@Controller 
public class LoginInterfaceController{ 

protected final Log logger = LogFactory.getLog(getClass()); 
@RequestMapping 
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 

    ModelMap model = new ModelMap(); 
    logger.info("Returning Login View"); 

    model.addAttribute(getLoginAttempt()); 

    return new ModelAndView("LoginView.jsp", model); 
} 

@ModelAttribute("LoginAttempt") 
public LoginAttempt getLoginAttempt() { 
    return new LoginAttempt(); 
} 

@RequestMapping(method=RequestMethod.POST) 
public String validateLogin(@ModelAttribute("LoginAttempt") @Valid LoginAttempt loginDetails, 
     BindingResult bindingResult, Model model, 
     @RequestParam(value="username", required=true) String username, 
     @RequestParam (value="password", required=true) String password) 
{ 
    String returnString; 
    LoginAttempt checkLogin = new LoginAttempt(username, password); 

    if(bindingResult.hasErrors()) 
    { 
     returnString = "LoginView.jsp"; 
    } 
    else if((!checkLogin.getUsername().equalsIgnoreCase("james") || !checkLogin.getPassword().equals("asdf123"))) 
    { 
     returnString = "FailedLogin.jsp"; 
    } 
    else 
    { 
     returnString = "redirect:" + "/ReferrerHome/"; 
    } 
    return returnString; 
} 

一旦用戶被驗證，它應該將它們重定向到/ ReferrerHome /頁面。

我LeadInterfaceController具有設置其請求的映射如下

@Controller 
public class LeadInterfaceController { 

private LeadServiceClass leadService = new LeadServiceClass(); 
protected final Log4JLogger logger = new Log4JLogger(); 

@RequestMapping(value="/ReferrerHome/") 
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 
    ModelMap model = new ModelMap(); 
    logger.info("Returning Referrer Home View"); 

    model.addAttribute(getLead()); 
    model.addAttribute(getBrokerList()); 
    return new ModelAndView("home.jsp", model); 
} 

@ModelAttribute("Lead") 
private Lead getLead() { 
    return leadService.getNewLead(); 
} 
@ModelAttribute("Broker") 
private ArrayList<Broker> getBrokerList(/*Referrer referrer*/) 
{ 
    return /*(ArrayList<Broker>)referrer.getBrokers() */ new ArrayList<Broker>(); 
} 

@RequestMapping(value="ReferrerHome/home.jsp", method=RequestMethod.POST) 
public String validateLogin(@ModelAttribute("Lead") @Valid Lead leadInput, BindingResult bindingResult, Model model)    
{ 
    String returnString; 
    if(leadInput.getLeadHomePhoneNumber() == null && 
      leadInput.getLeadWorkPhoneNumber() == null && 
      leadInput.getLeadMobilePhoneNumber() == null && 
      leadInput.getLeadEmail() == null){ 
     logger.info("HPhoneNum: " + leadInput.getLeadHomePhoneNumber()); 
     //code here to set an error state indicating that some contact information is required 
    } 
    if(bindingResult.hasErrors()) 
    { 
     returnString = "ReferrerHome/home.jsp"; 
    } 
    else 
    { 
     leadService.getLeadDao().addLead(leadInput); 
     returnString = "ReferrerHome/success.jsp"; 
    } 
    return returnString; 
} 

然而，當用戶被認證，則URL交換機/ ReferrerHome /但是LoginView.jsp被重新裝載，而不是被加載回到Home.jsp。 令人氣憤的是，這是2天前的工作，我不能想我做了什麼導致它破裂。

我撕裂我的頭髮試圖讓這個工作。

希望你能幫上忙。

Answer 1

您沒有映射到validateLogin中的路徑（僅限請求類型）。因此，當您返回「home.jsp」時，它將映射到validateLogin而不是@RequestMapping(value="ReferrerHome/home.jsp", method=RequestMethod.POST)。

嘗試： 1.返回ReferrerHome/home.jsp在LeadInterfaceController.handleRequest而不是home.jsp。 2.更改validateLogin上的映射，以便它包含它綁定的路徑（然後重定向後，您可以對錯誤有一個描述性錯誤）。

這應該有所幫助。

您也可以在DispatcherServlet上使用調試器並遵循流程（如何選擇「login.jsp」頁面）。
