java - 警告:在DispatcherServlet中，名称为“SpringLoginApplication”的URI [/SpringLoginApplication/]找不到HTTP请求的映射

当我在tomcat上运行该项目时，我的项目是一个maven项目
org.springframework.web.servlet.DispatcherServlet noHandlerFound
警告：在DispatcherServlet中，名称为“ SpringLoginApplication”的URI [/ SpringLoginApplication /]找不到HTTP请求的映射

我尝试了所有可能的方法来解决，但都可以，有人可以帮助我解决该问题

我的控制器：

    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");
        return "redirect:login";
    }

    @RequestMapping(value="/success", method = RequestMethod.GET)
    public String logOut(ModelMap model){

        model.put("customer", new Customer());
        return "redirect:success";
}

}

最佳答案

前几天我遇到了同样的问题，并且得到了下面的解决方案。

@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

}

由于您已将Dispatcher Servlet配置为处理上下文，而不是人们通常通过添加此（/ *）来处理上下文，因此以上提供的代码段将起作用，并将上下文重定向到所需的/ login（如果我是没有错）。干杯！！！！
