public class: Token [javadoc | source]
java.lang.Object
   org.apache.struts2.components.Component
      org.apache.struts2.components.UIBean
         org.apache.struts2.components.Token
Stop double-submission of forms.

The token tag is used to help with the "double click" submission problem. It is needed if you are using the TokenInterceptor or the TokenSessionInterceptor. The s:token tag merely places a hidden element that contains the unique token.

Examples


<s:token />

    First looks for the token in the PageContext using the supplied name (or org.apache.struts2.util.TokenHelper#DEFAULT_TOKEN_NAME if no name is provided) so that the same token can be re-used for the scope of a request for the same name. If the token is not in the PageContext, a new Token is created and set into the Session and the PageContext with the name.
 protected String getDefaultTemplate() 
 public String getTokenNameField() 
Deprecated! Templates - should use $parameters from now on, not $tag.

    This will be removed in a future version of Struts.
