Query Interface
---------------
Key: SEAMPERSIST-63
URL: https://issues.jboss.org/browse/SEAMPERSIST-63
Project: Seam Persistence
Issue Type: Feature Request
Reporter: Frank Cornelis
Priority: Minor
The query interface allows for easy usage of JPA queries. Basically you
annotate an interface as follows:
{code}
public interface QueryInterface {
@QueryMethod("person.query.all")
List<Person> getAll();
@QueryMethod("person.select.by.name")
Person getPersonByName(@QueryParam("name") String name);
@QueryMethod(value = "person.select.by.name", nullable = true)
Person findPersonByName(@QueryParam("name") String name);
@QueryMethod("person.query.all")
Query getAllQuery();
@QueryMethod(query = "SELECT COUNT(*) FROM Person")
Long countAll();
}
{code}
Using some inject QueryInterfaceFactory you can get a proxy on this interface
that will interpret the annotations towards JPA queries. See attached patch for
a basic implementation.
