我使用过STS,现在我正在使用IntelliJ Ultimate Edition,但我仍然得到相同的输出.我的控制器未映射,因此显示404错误.我是Spring Framework的新手.

DemoApplication.java

package com.webservice.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
public class DemoApplication {

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

HelloController.java

package com.webservice.demo;


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

@RestController
public class HelloController {

    @RequestMapping("/hello")
    public String sayHello(){
        return "Hey";
    }

}

控制台输出
