测试例子

package com.example.myspringboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@SpringBootApplication
@Controller
public class MyspringbootApplication {

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

    @RequestMapping(value = "/test")
    @ResponseBody
    //前面两个也可以直接写成@GetMapping("/test")  然后@Controller改成@RestController
    public String test() {
        return "hello!";
    }
}
