在@Query注解注釋的JPQL語句中寫limit語句是會報錯的
unexpected token :limit near line ....
解決方法是講@Query注解中的limit語句去掉,然后傳一個Pageable pageable=new PageRequest(offset,limit)進去
示例代碼:
controller
import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping(value = "/misaka") public class MisakaController { @Autowired private MisakaService misakaService; @RequestMapping(value = "/list") public List<Misaka> getBaselineOverview() { return misakaService.getMisaka(); } }
service
import java.util.List; public interface MisakaService { List<Misaka> getMisaka(); }
serviceimpl
import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.domain.Page; import org.springframework.data.domain.PageRequest; import org.springframework.data.domain.Pageable; import org.springframework.data.domain.Sort.Direction; import org.springframework.stereotype.Service; @Service public class MisakaServiceImpl implements MisakaService { @Autowired private MisakaDao misakaDao; @Override public List<Misaka> getMisaka() { Pageable pageable = new PageRequest(1, 2, Direction.ASC, "name"); Page<Misaka> misakaPage = misakaDao.search(pageable); List<Misaka> misakaList = misakaPage.getContent(); System.out.println(misakaList); return misakaList; } }
dao
import org.springframework.data.domain.Page; import org.springframework.data.domain.Pageable; import org.springframework.data.jpa.repository.Query; import org.springframework.data.repository.CrudRepository; public interface MisakaDao extends CrudRepository<Misaka, Long> { @Query("SELECT m FROM Misaka m WHERE m.id>4") Page<Misaka> search(Pageable pageable); }
model
import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name = "t_test") public class Misaka { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Column(name = "name") private String name; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "Misaka [id=" + id + ", name=" + name + "]"; } }
數(shù)據(jù)庫t_test
id | name |
---|---|
1 | m1 |
2 | m2 |
3 | m3 |
4 | m4 |
5 | m5 |
6 | m6 |
7 | m7 |
8 | m8 |
9 | m9 |

以上這篇在JPA的@Query注解中使用limit條件(詳解)就是小編分享給大家的全部內(nèi)容了,希望能給大家一個參考,也希望大家多多支持億速云。
