Class CreateSessionInterceptor
java.lang.Object
org.apache.struts2.interceptor.AbstractInterceptor
org.apache.struts2.interceptor.CreateSessionInterceptor

This interceptor creates the HttpSession if it doesn't exist, also SessionMap is recreated and put in ServletActionContext.

Interceptor parameters:
- None
- None
Example:
 
 <action name="someAction" class="com.examples.SomeAction">
     <interceptor-ref name="createSession"/>
     <interceptor-ref name="defaultStack"/>
     <result name="input">input_with_token_tag.ftl</result>
 </action>
