springboot与传统方法工程的基本步骤

@RestController //相当于Controller ResponseBody
@RequestMapping("/user")
public class UserController {

    @GetMapping("/json")
    public String getJson(){
        return "Hello World!";
    }
}

//主启动类
@SpringBootApplication
public class SpringbootMybatisApplication {

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

}
