JPA/SpringBoot Repository for database view (not table)

1. Create View with native SQL in the database,

create or replace view hunters_summary as 
select 
em.id as emp_id, hh.id as hh_id
from employee em 
inner join employee_type et on em.employee_type_id = et.id  
inner join head_hunter hh on hh.id = em.head_hunter_id;

2. Map that, View to an ‘Immutable Entity’

package inc.manpower.domain;

import org.hibernate.annotations.Immutable;
import org.hibernate.annotations.Subselect;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import java.io.Serializable;
import java.util.Date;

@Entity
@Immutable
@Table(name = "`hunters_summary`")
@Subselect("select uuid() as id, hs.* from hunters_summary hs")
public class HuntersSummary implements Serializable {

    @Id
    private String id;
    private Long empId;
    private String hhId;

    ...
}

3. Now create the Repository with your desired methods,

package inc.manpower.repository;

import inc.manpower.domain.HuntersSummary;
import org.springframework.data.repository.PagingAndSortingRepository;
import org.springframework.stereotype.Repository;

import javax.transaction.Transactional;
import java.util.Date;
import java.util.List;

@Repository
@Transactional
public interface HuntersSummaryRepository extends PagingAndSortingRepository<HuntersSummary, String> {
    List<HuntersSummary> findByEmpRecruitedDateBetweenAndHhId(Date startDate, Date endDate, String hhId);
}
