Question

我设置了所有想法，项目正在建设中没有错误但是当我尝试检查网站(http://localhost:8080/webstoreapp)上的结果时，它显示：

Whitelabel错误页面此应用程序没有明确的映射   /错误，所以你看到这是一个后备。

2月27日星期二12:05:16 GMT 2018出现意外错误（type = Not   找到了，状态= 404）。没有可用的消息

package com.exovsky.webstoreapp;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
public class WebstoreappApplication {

    public static void main(String[] args) {

        SpringApplication.run(WebstoreappApplication.class, args);

    }

}

package com.exovsky.webstoreapp.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Controller
 public class HomeController {
    @RequestMapping("/")
    public String welcome(Model model) {
        model.addAttribute("greeting", "Witaj w sklepie internetowym!");
        model.addAttribute("tagline", "Wyjątkowym i jedynym sklepie 
                           internetowym");
        return "welcome";
     }
