I am using Struts2. I am doing validations using annotations in action class.
I have many forms having same type of fields say zip code.
I am adding validations like below in each action class having zip code field
Now, in case if I need to change the expression for zip code validations, then I need to modify the same in each action class.
I would like to know if there is any way to use java variable or property for expression so that i only need to change at one place (value of variable) and all actions get modified.
I want something like below
