Setting default values in Java Beans / Data transfer Objects

Question

We use Data Transfer Objects (DTO) in our code. When constructing them, it is inevitable that some of their fields will have null values as some of those fields are null in the database. We were told that all null values must be default to "NA".

I know we can implements this the "hard way" by putting logic in the get methods of the DTOs. Question is, is there a better way to do this? I tried using @Value annotation of Spring to set its default values but this does not work.

Can anyone help? Thank you.

That shouldn't be done in the DTO layer. It should be done in the UI layer, when displaying the values in the DTO. — JB Nizet, Apr 27 '16 at 12:25
But if we want to implement this in the back end. Is there any easier way? — Eloijza Pavlova, May 19 '16 at 03:28

if you dont have a front end, you have to do it at the get method. (add in if statement for null?)
