Spring Boot无法启动

时间：2019-01-21 13:41:54

标签： java spring apache spring-boot tomcat

我有一个错误，我试图在2个小时内找出问题所在，但无法修复。

我使用java -jar命令运行了我的spring boot应用程序，它是一个程序包，无法启动。

我将属性文件设置为80端口，并且我的firewalld被禁用，我在Centos7机器上运行。我尝试了netstat命令，但端口80没有服务，所以我认为这不是端口问题。

这是错误消息：

Description:

The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 80, or configure this application to listen on another port.

日志说明了一切。

  

配置为侦听端口80的Tomcat连接器无法启动。   该端口可能已在使用中，或者连接器配置错误。

该端口当前正在使用，您此时可能有其他服务器正在使用该端口（可能是另一个运行/调试程序？）。无论如何，出于开发原因，我建议完全使用其他端口。

在application.properties中放入server.port=8080或类似内容-较小的机会被其他进程使用。
