java - Tomcat 意外关闭

Question

我一直在研究 xampp tomcat 服务器，我是新手。我配置了它并启动了 xampp tomcat。它工作正常，我看到我配置的所有端口都完美，但 3 分钟后它向我显示此错误

"Error: Tomcat shutdown unexpectedly.
4:55:38 PM  [Tomcat]    This may be due to a blocked port, missing dependencies, 
4:55:38 PM  [Tomcat]    improper privileges, a crash, or a shutdown by another method.

我打开 Catalina 日志以获取更多信息，我注意到这个 java 错误:

参见:

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

Tomcat 配置使用的端口已被另一个应用程序使用。

要么关闭其他应用程序，要么编辑您的 server.xml 文件以使用另一个端口(默认端口为 8080)。
