migration from 3.1 to 4.5

[Ethan47345]

Greetings！
I need to upgrade from 3.1 to 4.5. Should I just follow the files in the csrfguard-test-jsp directory? for example, web.xml and .properties files. If so, the tag configuration in web.xml

<listener>
	<listener-class>org.owasp.csrfguard.CsrfGuardHttpSessionListener</listener-class>
</listener>

doesn't seem to match up. there is no such class in the directory org.owasp.csrfguard

Hello @Ethan47345,

Have you taken a look at the bundled test application in this repository? That should be a good enough starting point.
Starting from version 4.x I've added support for stateless applications, hence all the logic required for stateful application support has been moved to a separate maven module.

The CsrfGuardHttpSessionListener class is still present, but under the csrfguard-extension-session module.
