java - Tomcat启动失败，服务器8080端口已被占用

Question

Deploying on Apache Tomcat or TomEE
    profile mode: false
    debug mode: false
    force redeploy: true
Starting of Tomcat failed, the server port 8080 is already in use.

您好，我有一个基于 spring 框架的 MVC 项目，我正在尝试构建一个简单的 CMS 网站。

尽管由于对整个框架缺乏了解，我在实际运行它时遇到了问题，但我昨天正在研究它。

但今天我一次又一次地收到相同的消息，即使在尝试了其他开发人员建议的解决方案之后，比如通过命令提示符杀死正在使用该端口的进程，或者只是更改 server.xml 文件的端口号，甚至重新启动我的显然不能用的笔记本电脑。

我知道我可能会在 apache tomcat 日志文件中收到一些隐藏的异常消息，但我不确定在哪里查看？

非常感谢任何帮助，因为我一直坚持使用相同的消息和大量的帖子，这些帖子提出了具有不同变化的相同事物，但到目前为止没有任何效果。

编辑:

这是完整的 Apache Tomcat 或 TomEE 消息:

我看到了这个:

Caused by: java.net.BindException: Address already in use: bind

好的，我明白了，但我尝试杀死使用它的进程仍然没有，我要尝试使用 TCPView

编辑:这是我尝试使用 NetBeans 时的情况，一旦我开始使用 STS，我就不会遇到 tomcat 的任何问题。

Answer 1

尝试列出所有应用程序及其端口，检查使用 8080 的应用程序并尝试杀死它，或者您可以直接杀死正在使用该端口的任何应用程序

第二个选项是使用任何可用端口更改 tomcat 服务器的端口

希望能解决你的问题
