发生的情况如下：

war 文件已创建。
集成测试类运行（打开浏览器，然后关闭浏览器）。
tomcat 服务器启动并部署应用程序。
ISSUE: 部署后我得到 java.lang.OutOfMemoryError: PermGen space 虽然我在 catalina.bat 和 cargo 配置中增加了内存，但我可以看到战争是部署在货物输出文件夹中，所以我想知道为什么会出现此异常？

【解决方案2】：

尝试在运行 maven 构建的环境变量中设置 MAVEN_OPTS=-XX:MaxPermSize=384m（或一些合适的数字）。

【讨论】：

我已经有MAVEN_OPTS=-Xmx512m -Xms256m -XX:MaxPermSize=1024m
它到底发生在构建的什么地方？您可以发布输出的摘录吗？
尝试使用 jconsole 检查 tomcat 实例实际上正在接收 PermGen 覆盖
