Macos MAC Intellij Idea无法在端口80上运行Web项目

我有一个使用J2EE的Web应用程序项目，我想使用apache tomcat在端口80上运行我的Web应用程序，我给出了以下错误：

下午4:31:34运行测试时出错：地址localhost:80已在使用中 下午4:31:37运行测试时出错：无法打开调试器端口：java.net.SocketException“套接字已关闭”

我使用此命令显示所有进程

对于这个命令，我给出这个输出

我认为osx或etc的另一个进程使用端口80。

你知道吗？

试试

$sudolsof-Pn-i|grep:80（听）“

我想你会得到

httpd     6477            root    5u     IPv6 0x261be06accde8493        0t0                 TCP *:80 (LISTEN)
httpd     6484            _www    5u     IPv6 0x261be06accde8493        0t0                 TCP *:80 (LISTEN)

这意味着：您的mac web服务正在运行。 如果您使用的是Mountain Lion或更高版本，我也希望您曾经在较旧的操作系统版本中通过启用过它。不幸的是，我没有禁用服务。。。在我看来就是这样。也许它也通过后台的timeMachine restore被重置了

• 临时卸载：

  sudo apachectl stop

• ：

  sudo launchctl unload-w/System/Library/LaunchDaemons/org.apache.httpd.plist

第一次运行项目时是否发生此错误？是的，我在第一次运行项目时出现此错误，我必须在项目中使用此端口80，原因有很多。这在Mac上不起作用，原因与它在任何其他基于Unix的操作系统上不起作用相同。有关更多信息，请参阅。
