             Summary: Introduce extension points in the existing Java EE commands
                 Key: FORGE-2752
                 URL: https://issues.jboss.org/browse/FORGE-2752
             Project: Forge
          Issue Type: Enhancement
          Components: Java EE
    Affects Versions: 3.7.0.Final
            Reporter: George Gastaldi
             Fix For: 3.x Future


JPA and REST commands are used in the Java EE addon but could perform differently when using another technology (like Spring Boot, for example). 

Example: 

JPA: In Spring Boot, there is no {{persistence.xml}}, but an {{application.properties}} file that contains the necessary information.

REST: Even though JAX-RS is not used, the generated REST endpoints would need extra annotations to perform correctly. This is accomplished now 

Right now the JPASetupWizard for example delegates the action to a PersistenceOperations class directly. It would be nice if we could introduce some indirection (or even extract to a common addon) in the commands.execute() method.

One idea is to have a Command -> Facet -> Operations, so other technologies (like Spring Boot) could reuse the same command by only implementing a different facet.
