Mac OSX 10.9.5 / Tomcat 7.0.62/ java version "1.8.0_45"/ IDEA 14.1.3
我在将IDEA设置为本地Tomcat服务器配置时，遇到了一些奇怪的问题。
单独运行Tomcat脚本（例如startup.sh或catalina.sh start | run），Tomcat会立即启动，并且web应用程序可以从浏览器中访问。在IDEA中运行命令行应用程序也能够立即运行。问题只在我尝试从IDEA中运行Web应用程序并将其部署到Tomcat本地时出现。更改配置中的浏览器无效。
当我点击“运行”按钮时，在大约5分钟内输出窗口中没有任何信息。之后，Web应用程序实际上开始运行，并且以下输出显示在IDEA输出窗口中:
/usr/local/tomcat7/bin/catalina.sh run

关于这一行的内容已经有了一些帖子：
Artifact thought_test:war exploded: Server is not connected. Deploy is not available.
但是所有给出的解决方案都不起作用。我看不到任何使用大量资源的活动，会导致延迟。这真的很奇怪，因为在延迟之后，与服务器的连接可以正常工作，即使最初无法连接。
更新:
我追踪到了防火墙。在“安全性与隐私”->“防火墙” -> “防火墙选项……”中，我取消了“启用隐身模式”的选择。之后，在IDEA和浏览器（Chrome）中启动应用程序。请注意，我首先将IDEA和Chrome添加到防火墙的“允许传入连接”的应用程序列表中，但那并不重要。
我会将其标记为解决方案，但我更想知道为什么Mac OS防火墙中有一些东西将IDEA到Tomcat的连接视为Ping或ICMP，并在几分钟内阻止它。
