mybaits長整形long與時間戳mysql timestamp數據轉換

借用MySQL函數實現

1. long 轉 timestamp：FROM_UNIXTIME(long, [format])

示例：限制10位時間戳，13位不可以
FROM_UNIXTIME(1249488000)
或
FROM_UNIXTIME(1249488000, '%Y-%M-%d %H:%m:%s')

整合到mybatis leaveTime為long型

<insert id="insertLiveOrder" parameterType="map">
        insert into
        reserve_record(orderId, uname, phoneNumber, roomType, reserveTime, preFee, status, startTime, endTime)
        values (#{orderId}, #{uname}, #{phoneNumber}, #{roomType}, NOW(), #{preFee}, 0,
        FROM_UNIXTIME(#{signTime}), FROM_UNIXTIME(#{leaveTime}))
</insert>

2. timestamp轉long：UNIX_TIMESTAMP

示例：

UNIX_TIMESTAMP('2020-07-11')
