import org.springframework.web.bind.annotation.ResponseBody;  

@Controller  
@EnableAutoConfiguration  	
@SpringBootApplication
public class HelloWorld {

	public static void main(String[] args) {
		//第一個簡單的應用，  
        SpringApplication.run(HelloWorld.class,args);
	}

	@RequestMapping("/hello")  
    @ResponseBody  
    public String hello(){  
  
        return "Hello World";
