需要在tomcat的server.xml中配置：

Java代码 

1. maxHttpHeaderSize="8192"   

上面这行配置在这里：

Java代码 

1. <Connector port="8080" protocol="HTTP/1.1"  
2.   maxHttpHeaderSize="8192"   
3.                        connectionTimeout="20000"  
4.   maxThreads="150"  
5.   maxSpareThreads="75"  
6.            redirectPort="8443" />
