如果有多个页面，则Java Spring JPA分页不起作用

Question

我正在尝试将jpa分页与自定义查询结合使用。

如果符合2种情况，分页是可行的。

案例1：

< li >如果可用数据少于10并且请求页码为0

如果不是请求不工作

和

案例二:

• 如果可用数据超过10，且页码为1的请求

如果不是分页不工作。

我无法弄清楚问题。有什么帮助吗？

提前感谢。

@Repository
public interface SmsLogRepository extends JpaRepository<SmsLog, Long> {

@Query(value = "select * from sms_log s where s.phone_number = (:ph) \n#pageable\n", nativeQuery = true)
Page<SmsLog> findByPhoneNumber(@Param("ph") String phoneNumber, Pageable pageable);

@Query(value = "select * from sms_log s where s.phone_number = (:ph) AND s.message_timestamp between (:fromdate) and (:todate) \n#pageable\n", nativeQuery = true)
Page<SmsLog> findByPhoneNumberAndDate(@Param("ph") String phoneNumber, @Param("fromdate") String fromDate, @Param("todate") String todate, Pageable pageable);

@Query(value = "select * from sms_log s where s.message_timestamp between (:fromdate) and (:todate) \n#pageable\n", nativeQuery = true)
Page<SmsLog> findByDate(@Param("fromdate") String fromDate, @Param("todate") String todate, Pageable pageable);
}

请求：

PageRequest pageRequest = new PageRequest(page, 10, new Sort(new Sort.Order(Sort.Direction.DESC, "message_timestamp")));
            return logRepository.findByPhoneNumber(ph, pageRequest);

花了一段时间后，我找到了答案

我错过了计数查询。添加计数查询后，分页的工作方式类似于超级按钮:)

@Repository
public interface SmsLogRepository extends JpaRepository<SmsLog, Long> {

@Query(value = "select * from sms_log s where s.phone_number = (:ph) \n#pageable\n", countQuery = "select count(*) from sms_log s where s.phone_number = (:ph) \n#pageable\n", nativeQuery = true)
Page<SmsLog> findByPhoneNumber(@Param("ph") String phoneNumber, Pageable pageable);

@Query(value = "select * from sms_log s where s.phone_number = (:ph) AND s.message_timestamp between (:fromdate) and (:todate) \n#pageable\n",countQuery = "select count(*) from sms_log s where s.phone_number = (:ph) AND s.message_timestamp between (:fromdate) and (:todate) \n#pageable\n", nativeQuery = true)
Page<SmsLog> findByPhoneNumberAndDate(@Param("ph") String phoneNumber, @Param("fromdate") String fromDate, @Param("todate") String todate, Pageable pageable);

@Query(value = "select * from sms_log s where s.message_timestamp between (:fromdate) and (:todate) \n#pageable\n",countQuery = "select count(*) from sms_log s where s.message_timestamp between (:fromdate) and (:todate) \n#pageable\n", nativeQuery = true)
Page<SmsLog> findByDate(@Param("fromdate") String fromDate, @Param("todate") String todate, Pageable pageable);
}
