在JPA的@Query注解中使用limit条件

来源：互联网发布：怎么开淘宝外包公司编辑：程序博客网时间：2024/05/14 09:12

在@Query注解注释的JPQL语句中写limit语句是会报错的

unexpected token :limit near line ....

解决方法是讲@Query注解中的limit语句去掉，然后传一个Pageable pageable=new PageRequest(offset,limit)进去

示例代码：

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;@Servicepublic 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 + "]";    }}

数据库t_test

idname1m12m23m34m45m56m67m78m89m9

输出

Hibernate: select count(misaka0_.id) as col_0_0_ from t_test misaka0_ where misaka0_.id>4Hibernate: select misaka0_.id as id1_29_, misaka0_.name as name2_29_ from t_test misaka0_ where misaka0_.id>4 order by misaka0_.name asc limit ?, ?[Misaka [id=7, name=m7], Misaka [id=8, name=m8]]
