Question

我的項目映射是一個行家項目，當我在Tomcat運行項目它顯示 org.springframework.web.servlet。 DispatcherServlet的noHandlerFound 警告：未找到HTTP請求與URI的映射[/ SpringLoginApplication /]在DispatcherServlet的名爲「SpringLoginApplication」

我嘗試所有的可能性來解決，但所有的靜脈，有人可以幫我解決這個問題

my controlle R：

package com.spring.login.controller; 

     import javax.servlet.http.HttpSession; 
     import javax.validation.Valid; 

     import org.springframework.beans.factory.annotation.Autowired; 
     import org.springframework.stereotype.Controller; 
     import org.springframework.ui.ModelMap; 
     import org.springframework.validation.BindingResult; 
     import org.springframework.web.bind.annotation.*; 

     import com.spring.login.beans.Customer; 
     import com.spring.login.services.CustomerService; 
     import com.spring.login.validation.CustomerValidation; 

     @Controller 
     public class CustomerController { 

     @Autowired 
     private CustomerService customerService; 

     @RequestMapping(value="/" , method=RequestMethod.GET) 
     public String login(ModelMap model){ 
     //model.put("Info", new Customer()); 
     return "/login"; 
    } 

    @RequestMapping(value="/register", method = RequestMethod.GET) 
    public String showForm(ModelMap model){ 
    model.put("customerData", new Customer()); 
    return "/register"; 
    } 


    @RequestMapping(value= "/register", method= RequestMethod.POST) 
    public String saveForm(ModelMap model, @ModelAttribute("customerData") @Valid Customer customer, BindingResult br, HttpSession session){ 
    CustomerValidation customerValidation = new CustomerValidation(); 
    customerValidation.validate(customerValidation, br); 
    if(br.hasErrors()){ 
    return "/register"; 
    } 
    else{ 
     customerService.saveCustomer(customer); 
     session.setAttribute("customer", customer); 
     return "redirect:success"; 
     } 
    } 
    @RequestMapping(value="/logout", method = RequestMethod.GET) 
    public String logOut(ModelMap model, HttpSession session){ 

     session.removeAttribute("customer");

我前幾天有同樣的問題，而且我得到了波紋管的解決方案。

@Controller 
@RequestMapping(value="/") 
public class CustomerController { 

//do your stuff here 
@RequestMapping(method=RequestMethod.GET) 
    public String login(ModelMap model){ 
    //model.put("Info", new Customer()); 
    return "/login"; 
} 

//Rest of your stuff goes here 

}

既然你已經配置了調度servlet來處理在所有可能代替你的背景下，人們一般做加入這個（/ *），所以上面提供的代碼段將工作和重定向你上下文到/你想要的登錄（如果我沒有錯）。乾杯！！！！
