@Name("blog")
@Scope(ScopeType.STATELESS)
public class BlogService
{
@In(create=true) (1)
private EntityManager entityManager;
@Unwrap (2)
public Blog getBlog()
{
return (Blog) entityManager.createQuery("from Blog b left join fetch b.blogEntries")
.setHint("org.hibernate.cacheable", true)
.getSingleResult();
}
}
The @Unwrap annotation tells Seam to provide the return value of the method—the Blog—instead of the actual BlogService component to clients. This is the Seam manager component pattern.
