@SpringBootApplication
public class Application {

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

}

7、Controller

package com.xx.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**

@RestController
public class TestController {

    // http://127.0.0.1:8001/test
    @RequestMapping("/test")
    public String test() {
        return "hello";
    }
}
