1.新建maven项目

2.配置pom.xml中的parent为spring-boot-starter-parent

    <parent>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-parent</artifactId>
     <version>2.3.4.RELEASE</version>
    </parent>

3.配置pom.xml中dependencies

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

4.编写启动类

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

注:
1)@SpringBootApplication  : 是Sprnig Boot项目的核心注解,目的是开启自动配置
2)启动类建议放到项目的根目录下面

5.编写controller

@RestController
public class HelloWorldController {
 @RequestMapping("/hello")
 private String home() {
 return "hello world";
 }
}

6.使用http://127.0.0.1:8080/hello访问
