Java.lang.IllegalArgumentException:Request header is too large resolution

When Tomcat runs the project, there is a request in the past, the backstage report such a mistake java.lang.IllegalArgumentException:Request header is too large

Reason: The request header exceeds the Tomcat limit. There is no parameter size limit for a POST request, but the server has its own default size.

Solve:

Approach: in Server.xml <connector connectiontimeout= "20000" port= "8080" protocol= "http/1.1" redirectport= "8443" Maxpostsize= "0" maxhttpheadersize = "102400"/>

Place plus maxhttpheadersize = "102400"
