Question

我正在尝试使用struts1.2form文件和apache.commons.fileupload 1.0上传一个巨大的文件大小[超过5 GB]。我看到struts1中文件上传的最大限制是256M。有没有办法改变这个？我得到以下例外。

默认文件大小限制为250MB。我增加到350MB。它工作正常。之后我将它增加到10G并获得以下异常。是否可以使用struts1.2上传一个巨大的文件？还有其他方法可以上传大文件吗？

Answer 1

配置struts的最大限制调节器 controller processorClass =“your class”nocache =“true”locale =“true”contentType =“text / html; charset = UTF-8”** maxFileSize =“15G”/ **

当您使用apache.commons.fileuploa-1.1时，存在一个约束，即FileUpload拒绝解析未知长度的请求。在随后的版本中引入了流来克服大小问题。以下问题在1.2＆amp; amp;中的apache.commons.fileupload中报告。 1.3 1.上传后，不删除临时文件 2.输入流未关闭，导致memleak。

参考：refuses parsing request of unknown lenght Memleak when stream is not closed. Memleak

希望它有所帮助......
