在JPA的@Query注解中使用limit条件

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;

@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 + "]";
}

}


数据库t_test

id	name
1	m1
2	m2
3	m3
4	m4
5	m5
6	m6
7	m7
8	m8
9	m9

输出

Hibernate: select count(misaka0_.id) as col_0_0_ from t_test misaka0_ where misaka0_.id>4
Hibernate: 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]]
