java - How to exclude a field when using a domain object for data transfer in Struts2

Question

In Struts2 it's very convenient to use domain driven in a action,however,The problem comes when the data gets automatically transferred onto the object. As we’ve seen, if the request has parameters that match the attributes on your domain object, the data will be moved onto those attributes. Now, consider the case where your domain object has some sensitive data attributes that you don’t really want to expose to this automatic data transfer, perhaps an ID,how can we exclude them? In asp.net mvc we can use exclude annotation to do it easily: Bind(Exclude="empId")], do we have similar approach to do this?
