请求标头太大

Question

我在日志中发现了几个IllegalStateException异常:

有人知道配置更改来解决这个问题吗？

Answer 1

在tomcat服务器xml上添加/更新

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" maxHttpHeaderSize="65536" maxPostSize="4194304"  
               URIEncoding="UTF-8"/>

Answer 2

正确的解决方案是在http-listener下添加以下属性:

<property name="maxPostSize" value="" />
