tomcat中的Java堆空间错误 [英] Java Heap Space Error in tomcat

问题描述

我使用的是 Tomcat 7.0.28.我已经部署了一个战争文件.在这个战争文件中有一个类似服务器的结构，我们可以在其中上传文件.

I am using Tomcat 7.0.28. I have deployed a war file. In this war file there is a server like structure where we can upload the files.

现在，当我访问该网页时，它可以正常工作，但是当我尝试上传大文件时，却显示 JAVA 堆空间错误.

Now when i access that web page it is working, but when i try to upload the large files it is showing error of JAVA Heap Space.

我该如何解决?

推荐答案

您可能正在尝试将整个文件放入内存中.您的第一个尝试应该是更改 Tomcat JVM 启动选项中的 -Xmx 参数，以提供更多记忆.除此之外，您必须一次读取一个文件块，并将其写入硬盘驱动器，以释放内存.

You are probably trying to put the whole file in memory. Your first shot should be to change the -Xmx parameter at the Tomcat JVM startup options to give it more memor. Aside from that, you'll have to read the file one chunk at a time, and write it on the hard drive, so as to free the memory.
