MyBatis 日期比较方式
create_time在数据库中是datetime类型
下列示例的结构是：mapper\xml中的SQL\idea控制台打印出来的日志。
其中1、2（1）、3的结果是一致的
1、Integer countTargetRewardSettleAccounts(
@Param("startTime") String startTime, @Param("endTime") String endTime);
SELECT
COUNT(*)
FROM target_reward_settle_accounts_daily
WHERE
create_time >= str_to_date( #{startTime},'%Y-%m-%d %H:%i:%s')
AND create_time < str_to_date( #{endTime},'%Y-%m-%d %H:%i:%s')

#{startTime,jdbcType=TIMESTAMP}，jdbcType=TIMESTAMP 时，就指定日期只用”年月日时分秒”,所有入参变为了‘yyyy-MM-dd HH24:mi:ss'’，如果什么都不加的话，默认是timestamp

SELECT
COUNT(*)
FROM target_reward_settle_accounts_daily
WHERE
create_time >= #{startTime,jdbcType=DATE}
AND create_time < #{endTime,jdbcType=DATE}

#{startTime,jdbcType=DATE}，jdbcType=Date 时，就指定日期只用”年月日”,所有入参变为了‘yyyy-MM-dd’。这个查询出来的数据不准确！！！！！！！！！！
(3) Integer countTargetRewardSettleAccountsByStr(
