 5 import org.springframework.data.jpa.repository.JpaRepository;
 6 import org.springframework.data.jpa.repository.Query;

 8 import com.hik.entity.Book;

15 public interface BookDao extends JpaRepository<Book, Integer>{
16     
17     //Hql语句查询
18     @Query("select b from Book b where b.bookName like %?1%")
19     public List<Book> findByBookName(String bookName);
20     
21     //本地sql语句查询
22     @Query(value="select * from t_book order by RAND() limit ?1",nativeQuery=true)
23     public List<Book> randomList(Integer n);
