public @Interface Param

Annotates a parameter of a repository method to bind it to a named parameter of a Query.

For example,

@Repository
public interface Products extends BasicRepository<Product, String> {

    @Query("WHERE length * width * height <= :maxVolume ORDER BY price ASC, id ASC")
    Page<Product> freeShippingEligible(@Param("maxVolume") float volumeLimit,
                                       PageRequest pageRequest);

    ...
}

The Param annotation is unnecessary when the method parameter name matches the query language named parameter name and the application is compiled with the -parameters compiler option making parameter names available at runtime.
