Class JSONValidationInterceptor
java.lang.Object
com.opensymphony.xwork2.interceptor.AbstractInterceptor
com.opensymphony.xwork2.interceptor.MethodFilterInterceptor
org.apache.struts2.json.JSONValidationInterceptor
- All Implemented Interfaces:
- Interceptor, java.io.Serializable
public class JSONValidationInterceptor
- extends MethodFilterInterceptor
Serializes validation and action errors into JSON. This interceptor does not
perform any validation, so it must follow the 'validation' interceptor on the stack.
This stack (defined in struts-default.xml) shows how to use this interceptor with the
'validation' interceptor
<interceptor-stack name="jsonValidationWorkflowStack">
<interceptor-ref name="basicStack"/>
<interceptor-ref name="validation">
<param name="excludeMethods">input,back,cancel</param>
</interceptor-ref>
<interceptor-ref name="jsonValidation"/>
<interceptor-ref name="workflow"/>
</interceptor-stack>
If 'validationFailedStatus' is set it will be used as the Response status
when validation fails.
If the request has a parameter 'struts.validateOnly' execution will return after
validation (action won't be executed).
A request parameter named 'struts.enableJSONValidation' must be set to 'true' to
use this interceptor
If the request has a parameter 'struts.JSONValidation.set.encoding' set to true
the character encoding will NOT be set on the response - is needed in portlet environment
