问题

以下是您的内容的中文翻译：

我的应用程序总是退出，并显示"进程以退出代码0结束"。
我尝试了不同版本的JAVA和Springboot，但每次都遇到相同的问题。

以下是运行输出和POM文件数据：

package com.technik.demotechnik;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemotechnikApplication {

	public static void main(String[] args) {
		SpringApplication.run(DemotechnikApplication.class, args);
		System.out.println("Hello, world!");
	}

}

我犯了一个愚蠢的错误。正如我所说，我是JAVA的新手，这确实是我的第一段代码。
***我在运行包而不是应用程序。***

I made a silly mistake there. As I told I am new to JAVA, this was indeed my first code.
***I was running the package instead of app.***
It just runs the test and that&#39;s the output pasted above.
