java - IntelliJ IDEA 14.1 缓慢启动 Tomcat 7 EE Web 应用程序

Question

Mac OSX 10.9.5/Tomcat 7.0.62/java 版本“1.8.0_45”/IDEA 14.1.3

我遇到了一些奇怪的行为，让 IDEA 作为本地 Tomcat 服务器配置向 Tomcat 发起爆炸式 war 。

就其本身而言，如果我运行它的脚本(即 startup.sh 或 catalina.sh start | run)，Tomcat 会立即启动，并且可以从浏览器访问 webapp .命令行应用程序在 IDEA 中立即运行。问题是当我从 IDEA 内部运行一个 Web 应用程序时，试图将分解的应用程序部署到 Tomcat 本地。更改配置中的浏览器无效。

当我点击“运行”时，输出窗口中没有大约 5 分钟。然后 web 应用程序真正运行，IDEA 输出窗口中显示以下输出:

/usr/local/tomcat7/bin/catalina.sh run

有几篇关于这条线的帖子:

Artifact thought_test:war exploded: Server is not connected. Deploy is not available.

但是没有一个给定的解决方案有效。我看不到正在发生的任何事情，看起来它正在使用大量资源，这会导致延迟。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，即使最初没有。

更新:

我追踪到防火墙。在“安全和隐私”->“防火墙”->“防火墙选项...”中，我取消选中“启用隐身模式”。在我这样做之后，该应用程序立即在 IDEA 和浏览器 (Chrome) 中启动。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，但这并不重要。

我会把它标记为一个解决方案，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 并阻止它几分钟。

Answer 1

您需要增加内存参数。

只需运行/调试配置并设置如图所示。希望它会比以前更好
