1、创建Maven工程,必须继承spring-boot-stater-parent工程
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.2.RELEASE</version> </parent>
2、编写Controller实现业务逻辑
import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import java.util.HashMap; import java.util.Map; @RestController public class HelloController { @RequestMapping("/hello") public Map sayWeiWu(){ Map map = new HashMap(); map.put("weiwu","java"); return map; } }
3、编写启动类,添加一个main方法,添加注解@SpringBootApplication
import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class WeiWuApplication { public static void main(String[] args) { SpringApplication.run(WeiWuApplication.class,args); } }
4、启动main方法
