package world;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

@RestController   

public class TestController {
    @RequestMapping(value="/hello",method=RequestMethod.GET) ---是跳转到hello。get方式提交
    public String say(){
        System.out.println("成功");
        return "hello spring boot";
    }
}

1. Controller, RestController的共同点

     都是用来表示Spring某个类的是否可以接收HTTP请求

2.  Controller, RestController的不同点

     @Controller标识一个Spring类是Spring MVC controller处理器

     @RestController：  a convenience annotation that does nothing more than adding the@Controller and @ResponseBody annotations。  @RestController是@Controller和@ResponseBody的结合体，两个标注合并起来的作用。

http://localhost:8080/hello
