Question

I have a repository interface with some abstract methods where I use the @Query annotation.
Now I would like to add limit and offset support to this queries.

example:

public interface ProductRepository
   extends CrudRepository<Product, Long> {

    @Query("from Product")
    List<Product> findAllProducts();
}

something like this would be nice

public interface ProductRepository
   extends CrudRepository<Product, Long> {

    @Query("from Product limit :limit ")
    List<Product> findAllProducts(@Param("limit") Integer limit);
}

But this doesn’t work. There is a solution that I create an implementation of the interface (http://stackoverflow.com/questions/3479128/jpql-limit-number-of-results)
But I wonder if there is not a possibility of adding offset and limit to the query or if there is an annotation for this.

Answer 1

limit is not supported by JPQL. Even without it your queries are not valid JPQL queries (but may be valid HQL – and may work if your JPA provider is tolerant).

A (partial) implementation is needed so you can use the Query interface or the criteria api.
