    最近做一个web项目中有上传文件的功能,已经写出并在本地和部署到服务器上测试了好几个文件上传都没问题(我用的是tomcat)。后来又上传了一个700多K的文件(前边的都是不足600K的,并且这个word文件用到了vb,比较复杂,可能造成读取较慢),在本地也是可以的,部署到服务器后在服务器上用服务器的本地浏览器上传也是可以的,但是部署到服务器上在其他地方通过浏览器访问上传却不行,情况是运行很久,然后出现“不能显示此页面”的字样。我就很奇怪,为什么同样的程序在本地和服务器上的效果却是不一样的?我看了服务器上tomcat下产生的日志,报的错误为

    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。
