在我的CI服务器上,我有一个需要启动Jetty服务器的测试
测试如下:
fuser
验证该端口是否未使用偶尔,即使验证端口是免费的,我也会得到例外:

运行的测试:
可能是什么原因?
谢谢!

当Jetty尝试启动时,端口49277
上已有一个进程。
没办法。
您可以询问Linux正在监听什么,并查看正在使用该端口的进程。
$ netstat -tlnp
但是,如果您想要的是Jetty可以启动和监听的随机端口,只需将Jetty应该使用的端口设置为0
,这将告诉TCP to randomly assign an available port when binding for listening。
然后,您的任务是弄清楚Jetty在启动后正在侦听的端口。

您可能在8080端口上使用tomcat请停止tomcat服务器并再次从maven运行jetty。
