Struts 2 add exception mapping for certain actions

Question

Consider a project with lots of annotated actions.

public class TransferMoney(){

    @Action("transfer-money-show-form")
    public String showForm();

    @Action("transfer-money-confirm")
    public String confirmForm();

    @Action("transfer-money-result")
    public String result();
}

I want to add exception-mapping to confirmForm so I can do it as:

@Action(value = "transfer-money-confirm", 
        exceptionMappings = 
                 {@ExceptionMapping(
                       exception = "java.lang.Exception", 
                        result = "exception")
                  }
        )

However is it a better way ?! As I said I have lots of actions and I don't want to add exceptionMapping for each of them one by one. The action name which I want to add mapping to them all ends with confirm but it seems not useful because the Exception Mapping does not accept regex.

@AleksandrM can i define a pattern for actions in global exception? For example if java.lang.Exception trues and the action name contains 'confirm' then redirect to a global page — Alireza Fattahi, Jun 08 '15 at 09:16
Not with pattern, no. But global exception mappings are per S2 package, so put you all *confirm* actions into separate package and enjoy. — Aleksandr M, Jun 08 '15 at 09:33

You can use <global-exception-mappings> in struts.xml. Global exception mappings are per S2 package, so you can define different mappings for actions by putting them into separate packages.

<package name="default">
    ...
    <global-exception-mappings>
        <exception-mapping exception="java.lang.Exception" result="exception"/>
    </global-exception-mappings>
    ...
</package>
