Annotate an entity bean with @View to indicates the bean is based on a view.


As such typically the view is defined in extra-ddl.xml using
create or replace view ....




When using extra-ddl.xml Ebean will run the resulting DDL script after the
create-all DDL (which is typically used during development) and for
DB Migration will copy the scripts as repeatable migration scripts that
will be run by FlywayDb (or Ebean's own migration runner) when their MD5 hash changes.
