Provide spring data query dsl repository for FactoryExpression with Predicate and Pageable for selecting specified columns [DATACMNS-383]

[spring-projects-issues]

Rajashekar opened DATACMNS-383 and commented

Please think of following Idea of providing a query dsl repository implementation for selecting specified columns. Presently we have QueryDslPredicateExecutor which allows to load all the records based on Predicate and Pageable.

By extending QueryDslPredicateExecutor implementation think of providing a Repository implementation to select records with specified columns based on FactoryExpression, Predicate and Pageable

For example the repository interface could be something like the following..

public interface QueryDslFactoryExpressionPredicateRepository<T>  	&#123;


    T findOne(FactoryExpression<T> factoryExpression, Predicate predicate);


    Iterable<T> findAll(FactoryExpression<T> factoryExpression, Predicate predicate);


    Iterable<T> findAll(FactoryExpression<T> factoryExpression, Predicate predicate, OrderSpecifier<?>... orders);



    Page<T> findAll(FactoryExpression<T> factoryExpression, Predicate predicate, Pageable pageable);

}
