I am looking for an alternative to Specifications for the given scenario

I am calling findall() method of the JpaRepository as following

Service 

on.findall(specificationsbuilder.getspecifications(params), paegable obj)  

specificationsbuilder.getspecifications(param)

returns specifications

My question is if specifications is null will my will findall(specifications,paegable) work

Solution

  • According to the sourcecode of SimpleJpaRepository it should work, because @Nullable says it will accept null:

    @Override
    public Page<T> findAll(@Nullable Specification<T> spec, Pageable pageable) {

        TypedQuery<T> query = getQuery(spec, pageable);
        return isUnpaged(pageable) ? new PageImpl<T>(query.getResultList())
                : readPage(query, getDomainClass(), pageable, spec);
}
