Невозможно открыть приложение Simple springboot на http://localhost:8088/hello

/ 11 марта 2019

Я новичок в Java и Springboot. Все, что я пытался сделать, это запустить простое приложение Springboot.

Среда: выпуск сообщества Intellji

Я все перепробовал. file-invalidatecahes / restart, указать базовый пакет контроллера. но ничего не работает

Ошибка при попытке открыть localhost в браузере: 

[This localhost page can’t be found
No webpage was found for the web address: http://localhost:8088/hello
Search Google for localhost 8088 hello
HTTP ERROR 404][1]

мой контроллер: 

package com.example.demo1.Controller;


import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class DemoController {
    @RequestMapping(value = "/hello", method = RequestMethod.GET)
    public String ram(){
        return "success the app is working";
    }

}

мой основной метод: 

package com.example.demo1;

import com.example.demo1.Controller.DemoController;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;


@SpringBootApplication
@ComponentScan(basePackageClasses = DemoController.class)
public class Demo1Application {

    public static void main(String[] args) {
        System.out.println("hi iam here 123");
        SpringApplication.run(Demo1Application.class, args);
    }

}

Выполнение журнала / трассировки стека: 

hi iam here 123
