Java Spring引导服务没有针对错误的显式映射,java,spring,reactjs,spring-boot,Java,Spring,Reactjs,Spring Boot,我创建了一个简单的spring启动项目和一个react应用程序。在src/main/java/com/example/i中有DemoApplication.java和DemoController.java：演示应用程序： package com.example; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplicat

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

演示应用程序：

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);
    }
}

演示控制器：

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>

检查此项-可能的重复性将index.html放入静态文件夹可能会产生重复。
