Question

我创建了一个简单的spring boot项目和一个react应用程序。在src / main / java / com / example /中有DemoApplication.java和DemoController.java：

DemoApplication：

package com.example;

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

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

DemoController：

package tutorial;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class DemoController {

    @RequestMapping(value = "/")
    public String index() {
        return "index.html";
    }
}

在src / main / resources / static / index.html中：

<!DOCTYPE html>
<html>
<head>
    <title>React + Spring</title>
    </head>
    <body>
    </body>
    </html>

然而，当我启动服务器时，我看到：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available

Spring引导服务不会对错误做出明确的maping反应
