* <p>名称：IdWorker.java</p>
9+
* <p>描述：分布式自增长ID</p>
10+
* <pre>
11+
* Twitter的 Snowflake　JAVA实现方案
12+
* </pre>
13+
* 核心代码为其IdWorker这个类实现，其原理结构如下，我分别用一个0表示一位，用—分割开部分的作用：
14+
* 1||0---0000000000 0000000000 0000000000 0000000000 0 --- 00000 ---00000 ---000000000000
15+
* 在上面的字符串中，第一位为未使用（实际上也可作为long的符号位），接下来的41位为毫秒级时间，
16+
* 然后5位datacenter标识位，5位机器ID（并不算标识符，实际是为线程标识），
17+
* 然后12位该毫秒内的当前毫秒内的计数，加起来刚好64位，为一个Long型。
18+
* 这样的好处是，整体上按照时间自增排序，并且整个分布式系统内不会产生ID碰撞（由datacenter和机器ID作区分），
19+
* 并且效率较高，经测试，snowflake每秒能够产生26万ID左右，完全满足需要。
20+
* <p>
21+
* 64位ID (42(毫秒)+5(机器ID)+5(业务编码)+12(重复累加))
