在DAO层里面声明了

int reduceNumber(@Param("seckillId")long seckillId,   @Param("killTime")Date killTime);

在mapper里面的语句是

 <update id="reduceNumber">
--         具体的sql
        UPDATE seckill
        SET number = number - 1
        WHERE seckill_id=#{seckillId}
        AND start_time <![CDATA[ <= ]]> #{killTime}    <!-- <=符号与SQL语句有歧义，这里必须这样写 -->
        AND end_time >= #{killTime}
        AND number > 0
    </update>
