[forge-issues] [JBoss JIRA] (FORGE-322) Support generation of @Entity "finder" methods

[Richard Kennard (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/FORGE-322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12648691#comment-12648691 ] 

Richard Kennard commented on FORGE-322:
---------------------------------------

Done in new scaffolding implementation. Well, sort of. I don't really grok what these 'finder' methods are all about. What if an entity has 3 fields? Do I need:

   public Customer findByFirstname(...) { ... }
   public Customer findBySurname(...) { ... }
   public Customer findByAddress(...) { ... }
   public Customer findByFirstnameAndSurname(...) { ... }
   public Customer findByFirstnameAndSurnameAndAddress(...) { ... }
   public Customer findBySurnameAndAddress(...) { ... }
   public Customer findByFirstnameAndAddress(...) { ... }

This seems unwieldy in Java? It works in, say, Ruby because they have 'method_missing'. But I don't like the idea of statically generating all these (when most will never be used).

So instead I've implemented a simple Query By Example into the scaffolding using Criteria queries. Will that be sufficient?

Please test!
