问题 I have debated this for a while now and still have not come to a conclusion. While most examples I see have the factories code in the application layer I tend to think it should be in the domain layer. Reasons for this: I sometimes have initial validation done in my factory where I want all creation of objects to go through. I want this code to be used on all instantiates of my object. Sometimes an operation requires parameter information which feels unnatural to pass to a constructor. And a

问题 In Patterns of Enterprise Application Architecture, Martin Fowler talks about two patterns for organizing Domain Logic: Domain Model and Service Layer. The Domain Model pattern is the "pure OOP" approach, where models (those objects that are probably being looked up from the database using an ORM) contain business logic (albeit, probably only delegating to the logic in another class). The Service Layer pattern is like the Domain Model pattern, but with a thin layer in front of it containing

问题 Currently I'm working on a project exploiting multi layer architecture as described in Application Architecture Guide 2.0 with 5 layers(DAL, BLL, Facade, Presentation Layer and Common Layer). Here we have a Business Logic Layer which consists of Business Components and Business Entities(which are entities generated using an O/R Mapper), regularly we need this entities in our presentation layer for binding and presenting data to the user so we bubble this entities up to the Presentation Layer

I want to add status dialog, representing loading screen with progress bar for Dialog::encAll() slot, after the progress bar reached max value to close the statusdialog.

问题 This question already has answers here : Confusion in Struts MVC architecture (2 answers) Closed 2 years ago . My MVC concept is not clear. It seems me that .xml files are for Modeling ; .jsp files are for Viewing ; .java files are for Controlling . This is actually represents MVC system.
