【问题描述】：

我使用 SpringSource Tool Suite 3.0.1、Tomcat 服务器 7.0.21、maven-2.2.1。 我成功构建了我的 Web 应用程序，运行了 Tomcat 服务器。该应用程序成功运行。重新启动 Tomcat 服务器后，我轮流看到下一个错误，网页 login.jsp 上有异常：

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.OutOfMemoryError: PermGen space

login.jsp - 主页由 SpringSecurity 配置。

我不明白问题的根源，因为我没有重建项目。 之后我尝试了几种错误恢复方法：

  • 刷新项目
  • 清理并重建项目
  • 更新 maven 依赖项
  • 清理 Tomcat 工作目录
  • 服务器菜单中的清理...按钮

没有任何方法对我没有帮助。 但应用程序的内部逻辑工作正常（它与 Web 界面无关）。我收到适当的日志消息。但是，一旦我打开页面 login.jsp，我就会收到错误消息。 然后我尝试恢复到项目的先前稳定版本。不幸的是，我遇到了同样的错误。

在logon.jsp页面输出错误信息前，登录控制台会显示如下信息：

02.04.2012 11:22:41 org.apache.jasper.compiler.TldLocationsCache tldScanJar
INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
02.04.2012 11:22:44 org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [appServlet] in context with path [/main] threw exception [Handler processing failed; nested exception is java.lang.OutOfMemoryError: PermGen space] with root cause
java.lang.OutOfMemoryError: PermGen space

我发现了类似的问题：http://www.mail-archive.com/users@tomcat.apache.org/msg54797.html 和 http://wiki.metawerx.net/wiki/Org.apache.jasper.JasperException。但这对我没有帮助。

如何解决这个问题？

【问题讨论】：

  • @Didgeridoo：你可以把问题分成两部分:)
  • login.jsp 是否位于 WEB_INF/views/ 中？
  • Tomcat 配置使用多少内存？您的应用程序需要多少内存？
  • @SrikanthVenkatesh 是的，login.jsp 位于文件夹 WEB_INF/views/ 中。
  • @BalusC 如何查看Tomcat中的内存配置？

【解决方案1】：

对于 OutOfMemory 错误，请确保您设置了以下参数（并且具有可观的值）

-Xmx1024m -XX:MaxPermSize=512m

编辑：

512m 和 1024m 只是建议！ 您可能需要将这些设置调整到您的硬件资源中。

通常您应该从 128m 左右的某个地方开始，每次遇到 OutOfMemory 错误时尝试将分配的数量加倍。

例如：

  • MaxPermSize 有 256m 并且您得到 OutOfMemory - 新阈值应设置为 512m

  • 您有 512m 的 MaxPermSize 并且您得到 OutOfMemory - 新阈值应设置为 1G

有关调优 JVM 参数的更多详细信息，请参阅 Java 官方文档Oracle。

【讨论】：

  • 谢谢！！！有用！我将这些参数添加到“Apache Tomcat v7.0.21”启动配置中的“VM 参数”中。我认为问题出在我的笔记本电脑内存不足。我关闭了几个应用程序，重新启动了 SpringSource 工具套件并且它工作了！
  • 我可以添加超过512M吗？如果是，我能给出的最大值是多少？
  • 是的，您可以添加超过 512M 的内存，但这取决于您有多少可用内存
  • 嗨，我是 Java 新手。你能解释一下我必须在哪里设置值吗？谢谢
【解决方案2】：

看起来 tomcat 无法编译 JSP，您可能需要考虑预编译 JSP（这会带来额外的好处，即在部署应用程序之前检查 JSP 的语法错误）。

另请参阅：How can I make Tomcat pre-compile JSPs on startup?

【讨论】：

    【解决方案3】：

    这取决于您正在运行的文件是 catalina.bat 还是 catalina.sh。如下设置Java选项并尝试：

    set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG% -Xms512m -Xmx512m -XX:PermSize=512m -XX:MaxPermSize=1024m

    【讨论】：

      【解决方案4】：

      只是Bogdan's answer的扩展版本
      1. 在 主菜单 转到 Window -> Show View -> Servers
      2. 在“Servers”视图中双击“Tomcat”
      3. Tomcat 概述 页面将打开
      4. 找到“一般信息”部分并点击“打开启动配置”
      5. 在 'Edit Configuration' 弹出窗口中转到 Arguments 选项卡
      6. 找到 'VM arguments' 部分并将 -Xmx1024m -XX:MaxPermSize=512m 放在那里
      7. 单击“确定”并启动您的 Tomcat。

      【讨论】：

      • 我可以添加超过512M吗？如果是，我能给出的最大值是多少？
      • 是的，你可以。最大值受机器上的本机内存量限制，具体取决于 32/64 位 JVM 和操作系统内存可用性。 PS：还要注意，从 Java 8 开始，PermGen 已经被 MetaSpace 区域所取代。所以参数是 -XX:MaxMetaspaceSize=512m
