WAR 文件在 Tomcat 服务器中抛出 OutOfMemoryError

我有一个 Spring MVC WAR 文件，可以在我的本地计算机（程序和网站）中完美运行。

一旦我将文件上传到服务器（aTomcat 7）并尝试访问它，catalina 日志文件表明java.lang.OutOfMemoryError.

我尝试过修改内存ArgumentsEclipse IDE 的选项卡Run > Run Configurations通过附加部分-Xmx2048m or -Xmx1024m to the VM Arguments导出之前的部分，但除了第一个部分之外没有任何更改导致

Error occurred during initialization of VM
Could not reserve enough space for object heap

在我的本地机器上。

以下是我初次访问该网站时的完整日志文件：

我该如何解决这个问题？

正如评论部分所述，您必须增加服务器使用的 JVM 上的堆大小，而不是在 Eclipse 中（因为这仅在本地运行时有效）。

所以尝试将其设置为-Xmx512m or -Xmx1024m（或您需要的任何其他内容）。

如果您不知道如何执行此操作，请告诉我您正在运行的 Tomcat 版本和平台（Linux、Windows 等）。
