It's limited by tomcat, tomcat allow 10000 parameters by default, struts2 take two parameters per checkbox, 10000/2=5000 https://github.com/apache/tomcat/blob/884b997f5a9a7da9f696d00574d3b727afbfae8c/java/org/apache/catalina/connector/Connector.java#L224
you can change maxParameterCount in server.xml <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" maxParameterCount="1000000"/> Nikolay Ivanchev <nikolay.ivanc...@me.com> 于2021年1月19日周二 下午11:51写道： > Hi All > > Is there a hard limit of elements in a form when processed by Struts2 > We have a form with 11000 chekcboxes and when we submit it, only 5000 > checkboxes are sbumitted > > Is this a configurable parameter? > > Thanks > >
