Tomcat Post请求大小设置

根据官方文档http://tomcat.apache.org/tomcat-6.0-doc/config/http.html，我们可以看出，tomcat6在默认状态下最大的post请求是2M
maxPostSize
The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

如果需要修改的，就需要找到server.xml文件
<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"  maxPostSize="0" />
maxPostSize： 0 表示不限制
其中单位为：byte
自己看着算。
