UUID(Universally Unique Identifier)是通用唯一识别码,在许多领域用作标识,比如我们常用的数据库也可以用它来作为主键,原理上它是可以对任何东西进行唯一的编码的。 1、uuid1()基于时间戳 由MAC地址、当前时间戳、随机数字。保证全球范围内的唯一性。但是由于MAC地址使用会带来安全问题,局域网内使用IP代替MAC 2、uuid...

简介:通用唯一识别码(英语:Universally Unique Identifier,简称UUID)是一种软件建构的标准,亦为开放软件基金会组织在分布式计算环境领域的一部分。它是通过MAC地址, 时间戳, 命名空间, 随机数, 伪随机数来保证生成ID的唯一性, 有着固定的大小( 128 bit )。
