Struts 2 REST and validation

I'm using Struts 2 and the REST plugin. Validation in Struts 2 is Cla开发者_如何学JAVAssName-actionAlias-validation.xml. However, using the REST plugin the action alias is always /. For example OrdersController -> /orders -> OrdersController-orders-validation.xml. How can I get different validations depending on the REST method? Mainly, I want one type of validation for the update() method and another for the create() method.

Have you considered using annotations for the validations? That makes it simpler to tie them to the correct method.

Ahh, I didn't know that you could use annotation based validation on a specific method. I haven't used Struts that much. Thanks!

However, I did have to modify my struts.xml to allow different validations on different methods (validateAnnotatedMethodOnly had to be true). Here is what it looks like:
