How to search with JpaRepository and nested list of objects?

Question

Description

There is a PersonRepository and Person entity, Person class contains List

Answer 1

First, change experienceInMonths from String to int (otherwise you can not compare the string with the number). Then you can try to use this 'sausage':

List findByQualifications_experienceInMonthsGreaterThanAndQualifications_experienceInMonthsLessThanAndName(int experienceGreater, int experienceLess, String name);

Or you can try to use this pretty nice method:

@Query("select p from Person p left join p.qualifications q where q.experienceInMonths > ?1 and q.experienceInMonths < ?2 and q.name = ?3")
List findByQualification(int experienceGreater, int experienceLess, String name);
