How to specify multiple acceptParamNames in Struts2 using annotations (convention plugin)?

Question

I'm trying to set multiple acceptable parameters through the params interceptor like as follows.

@Namespace("/admin_side")
@ResultPath("/WEB-INF/content")
@InterceptorRefs({
    @InterceptorRef(value="defaultStack", 
        params={"params.excludeParams", "^action:(?!postAction$)\\w*$",
        "params.acceptParamNames", "action:postAction",
        "params.acceptParamNames", "id",
        "params.acceptParamNames", "name",
        "params.acceptParamNames", "email",
        "params.acceptParamNames", "number",
        "params.acceptParamNames", "deleteOneRow",        
        "validation.excludeMethods", "test"}),            
})
public final class TestAction extends ActionSupport implements Serializable, ValidationAware, ModelDriven<Transporter>
{
    //...
}

In this case, only the last parameter which is deleteOneRow (Boolean) is accepted. The rest are not accepted. Instead, it issues warnings as follows.

How to set multiple parameters to params.acceptParamNames using convention plugin?

Answer 1

So, the answer is as simple as follows.

@InterceptorRefs({
    @InterceptorRef(value="defaultStack", 
    params={"params.excludeParams", "^action:(?!postAction$)\\w*$",
   "params.acceptParamNames", "^action:(?!postAction$)\\w*$, id, name, email, number, deleteOneRow", 
    "validation.excludeMethods", "test"})
})

Among from these parameters, ^action:(?!postAction$)\\w*$ is a parameter of submit button, <s:submit> that doesn't work issuing a warning, WARNING: Parameter [action:postAction] didn't match acceptParams list of patterns! but it could be a different question.
