What is the accepted naming convention for web form backing objects in Java/Spring?

Question

I have a Java web application built using Spring MVC. I have a set of JSPs which are the pages, and a set of "model" objects which are sent to the JSPs to populate/receive the form data. Here is a simplified view from the JSP down to the database layer:

showCustomer.jsp  // JSP page using the "CustomerViewDao"
org.mycompany.views.CustomerViewDao  // view backing (model) object
org.mycompany.controller.CustomerController // controller layer
org.mycompany.service.CustomerService // service layer
org.mycompany.model.Customer // Hibernate entity

Is there an accepted naming convention for these model objects? I chose "xxxDao" for "Data Access Object" and was told this was not a "good" choice. Is there a better choice and what would it be?

Answer 1

Firstly, there is no "accepted naming convention". However, some people have good ideas about these things ... eg trawl through the answers to this: What naming convention do you use for the service layer in a Spring MVC application?

For what it is worth, I probably would have chosen xxxDao too ... assuming that the object really is a DAO. But obviously, your reviewer had different ideas. You should ask him (or her) for suggestions ... not us! (What is to say that he won't arbitrarily reject your next N choices as being "not good"?)

On the other hand, he might have rejected your choice of "xxxDAO" because the object / class is not a DAO (Data Access Object) in the normal sense of that term. Your description ... "view-backed (model) object" ... does not really match the normal usage of DAO.
