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.
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 can increase HeapSizein tomcat using below command .
您可以HeapSize使用以下命令增加tomcat。
Linux :Open Catalina.shfile placed in the "bin" directory. You have to apply the changes to this line
Linux：打开放置在“bin”目录中的Catalina.sh文件。您必须将更改应用于此行
CATALINA_OPTS="$CATALINA_OPTS -server -Xms256m -Xmx1024m "
Windows:
视窗：
Open the "Catalina.bat" file placed in the "bin" directory
打开放置在“bin”目录下的“ Catalina.bat”文件
set CATALINA_OPTS=-server -Xms256m -Xmx1024m
Restart the tomcat after above change.
以上更改后重新启动tomcat。
