• 添加依賴

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.15.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 </dependencies>

• 添加啓動類

package com.tzb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@EnableAutoConfiguration
public class App {

    @RequestMapping("/")
    public String hello(){
        return "hello world";
    }

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

}
