Я пытаюсь создать базовое приложение для весенней загрузки (JDK 1.8) с REST API.
Ниже приведен код моего приложения
package org.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan("org.demo")
@EnableAutoConfiguration
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
Я добавил простой контроллер следующим образом
package org.demo.controllers;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
@RestController(value = "/hello")
public class HelloController {
@GetMapping
@ResponseBody
public String hello() {
return "Hello";
}
}
Файл POM моего проекта выглядит следующим образом

Когда я запускаю это приложение, оно запускается успешно. Однако, когда я пытаюсь попасть по URL localhost: 8080 или loclahost: 8080 / hello, я получаю сообщение об ошибке 404
Ниже приведены журналы запуска
