上传文件报错:Processing of multipart/form-data request failed. Stream ended unexpectedly

web项目中,本地开发环境上传大文件没有问题,但是部署到服务器后上传大文件却不可以,看了服务器上tomcat下产生的日志,错误信息为:

一开始认为是网络的原因,网络超时而没有上传成功,然后百度寻找解决办法,如下:

1、首先,上传页面上面的 form 标签要设enctype="multipart/form-data" 参数

2、修改tomcat配置文件server.xml:

maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
将上面的参数disableUploadTimeout值改为false即可。

3、修改了tomcat配置文件server.xml中的另外一处:

port="8080" protocol="HTTP/1.1" 
connectionTimeout="20000" 
redirectPort="8443" /> 在里边加入disableUploadTimeout="false"一句。

以上解决方法在我的程序中已经设置,所以仍然不能解决问题。

然后无意中查看页面和js代码,发现一个问题:添加信息页面,在点击保存按钮后进行表单验证再form提交,然后提示添加成功信息,关闭添加tab页面,刷新list列表数据,但这就存在一个问题,如果上传文件过大就会导致文件没有上传完成而直接跳转到了list列表页面,进而导致上传失败。

解决方法:form提交后,不提示信息刷新数据,在页面重新加载的时候在进行提示、刷新。
