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.
