Sounds like a good idea. It adds a lot of freedom and easy customization to
be able to override the built in annotations, such as JPA annotations, for
special cases.
Please add tasks in Jira.
How should it look like in the DSL?
In Java, annotations are normally written before the element with @
It is always nice to use similar syntax.
We have already used @ to define reference to another domain object in the
DSL (to differentiate it from an ordinary java class). Should we rename that
to # ?
@TransactionAttribute(TransactionAttributeType.NEVER)
Service FooService {
#Foo foo(String bar);
}
Entity Foo {
@XmlElement
String name
@Transient
- #Country country
}
It must be possible to define several annotations for an element.
One tricky thing is that the DSL elements are not one-to-one to java and it
is often ambiguous where to place the annotation in the generated code. Do
we need some kind of additional placement hint for the annotation?
Do we add to much power to the DSL? Is it possible to solve in some other
other way?
