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 getBaselineOverview()
    {
        return misakaService.getMisaka();
    }

}

service

import java.util.List;

public interface MisakaService
{
    List 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 getMisaka()
    {
        Pageable pageable = new PageRequest(1, 2, Direction.ASC, "name");
        Page misakaPage = misakaDao.search(pageable);
        List 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
{
    @Query("SELECT m FROM Misaka m WHERE m.id>4")
    Page 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]]
