类 CreateSessionInterceptor

java.lang.Object
  com.opensymphony.xwork2.interceptor.AbstractInterceptor
      org.apache.struts2.interceptor.CreateSessionInterceptor

所有已实现的接口：

com.opensymphony.xwork2.interceptor.Interceptor, Serializable

public class CreateSessionInterceptor
extends com.opensymphony.xwork2.interceptor.AbstractInterceptor

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

This is particular useful when using the <@s.token> tag in freemarker templates. The tag do require that a HttpSession is already created since freemarker commits the response to the client immediately.

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>
