解决方案:

在weblogic下一模一样的代码,没有报错,tomcat却报错了,所以就怀疑是tomcat server本身存在问题.

一番百度后, 原来是tomcat默认的maxHttpHeaderSize只有8192,而我cookie放了大报文,导致head头信息量过大,无法存放.

在<connector> 节点中添加 maxHttpHeaderSize="81920" 解决问题,如下 :

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" maxHttpHeaderSize="81920"/>

 

最终发现<Connector中还可以配置最大线程 maxThreads="250"  超时时间connectionTimeout="20000" 等
