在STS上“作为Spring启动应用程序运行”，但浏览器中“网页不可用”[重复]

Question

正如标题所说，我右键点击spring boot项目，并作为spring boot应用程序运行。这是我在STS的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，但在那之后就停止了。

我已经尝试了runMVN spring-boot:run，它还注销了上面的信息加上build success，即使没有我Ctrl+C也会停止。所以我不知道如何运行我的“Hello World”spring-boot应用程序。

Answer 1

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>
