jpa limit

1.jpa支持native sql查询，所以你可以直接写sql查询得到数据

01	package com.zuidaima.springdata.repository;

02

03	import java.util.List;

04	import org.springframework.data.jpa.repository.JpaSpecificationExecutor;

05	import org.springframework.data.jpa.repository.Query;

06	import org.springframework.data.repository.PagingAndSortingRepository;

07	import org.springframework.data.repository.query.Param;

08	import com.zuidaima.springdata.entity.User;

09

10

/**

*/

13

14	public interface UserRepository extends PagingAndSortingRepository<User, Long>,

15	JpaSpecificationExecutor<User> {

16	@Query(value = "select * from user where id in(:ids)", nativeQuery = true)

17	List<User> findAllByIds(@Param("ids") List<Long> ids);

18

19	@Query(value = "from User where name=?1")

20	User findAllByName(String name);

21

}

2.jpa的PagingAndSortingRepository等内置类就支持分页查询

1	Page<T> findAll(Pageable pageable);

1

int p=1;

2	int ps=10;

3	Pageable pageable = new PageRequest(0, ps, sort);

通过new Pageable对象即可,注意page是从0开始
