Examples of org.apache.struts2.interceptor.validation.JSONValidationInterceptor

org.apache.struts2.components.Anchor
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 'enableJSONValidation' must be set to 'true' to use this interceptor
