 然后在百度和谷歌上各种搜索，大多数认为是超时而断开连接。对于解决办法一般给的不够全面，现综合给出如下：

（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，找到类似于下面配置:

<Connector port="8086" maxHttpHeaderSize="8192"
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）上边（1）是我的程序中已经设置的，修改了（2）所述的配置后依然不能运行，后来又修改了tomcat配置文件server.xml中的另外一处：

<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" /> 也在里边加入了disableUploadTimeout="false"一句。

用了以上方法仍然不能解决，后来想到可能是服务器外加了防火墙或者限制了上传文件的大小之类的，联系网络中心进行相关设置进行设置即可。
