'；作为Spring Boot应用程序运行'；关于STS，但是；“网页不可用”；在浏览器中

正如标题所说，我右键单击SpringBoot项目并作为SpringBoot应用程序运行。这是我在STS控制台窗口中看到的：

当我打开localhost:8080时，它只显示了一个灰色页面，上面写着“此网页不可用”。显然，服务器根本没有启动，或者它启动了，但随后就停止了

我已经试过运行

mvn spring boot:run

，它也会像上面那样注销信息，再加上

BUILD SUCCESS

，甚至在没有我的情况下也会停止运行

Ctrl+C

。所以我不知道如何运行我的“hello world”spring boot应用程序。

我通过在pom.xml中添加以下内容解决了这个问题：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

org.springframework.boot
