Web server failed to start. Port 8080 was already in use. mac

回答: 在Mac操作系统上，如果遇到"Web server failed to start. Port 8080 was already in use."的报错，表示8080端口已被占用。你可以通过以下步骤解决这个问题。首先，打开终端应用程序。然后，输入以下命令以查找占用8080端口的进程:

lsof -i :8080

该命令将显示占用8080端口的进程的信息，包括进程ID。记下占用8080端口的进程ID（PID）。接下来，输入以下命令以停止该进程:

kill PID

将PID替换为占用8080端口的进程的实际ID。此命令将终止该进程，释放8080端口。最后，重新启动你的Spring Boot项目，应该能够成功启动。如果问题仍然存在，请确保没有其他应用程序或服务正在使用8080端口，或者可以尝试将应用程序配置为使用其他可用端口。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
