Tomcat 由于本地计算机上的两个应用程序 运行，地址已在使用错误
Tomcat address already in use error due to two applications running on local machine
我的 Java 应用程序出现此错误：

我猜我的两个应用程序正试图在同一个端口上启动 Tomcat，但我对 tomcat 没有任何了解或经验。还假设它以某种方式嵌入到 SpringBoot 中。我如何 investigate/resolve 这个？
您可以在application.properties
中设置服务器端口
server.port=8081
或application.yml:
server:
port: 8081
两个文件之一可能存在于 src/main/resources 中，如果没有，您可以创建一个。
我假设您的机器已经具有您可能不需要的 8080 端口 运行。因此，要终止该连接，请遵循以下两个简单的步骤（如果您想为您的应用程序使用 8080）：
通过在您的终端上输入以下内容获取 8080 端口的 PID：netstat -n -a -o | grep '8080'
杀死进程释放8080端口：taskkill /F /PID 1234（假设PID为1234）
