+ * @author wuyunbin
+ * 名称：IdWorker.java
+ * 描述：分布式自增长ID
+ *
+ * Twitter的 Snowflake JAVA实现方案
+ *
+ * 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：
+ * 1||0---0000000000 0000000000 0000000000 0000000000 0 --- 00000 ---00000 ---000000000000
+ * 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，
+ * 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），
+ * 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。
+ * 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），
+ * 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。
+ *
+ * 64位ID (42(毫秒)+5(机器ID)+5(业务编码)+12(重复累加))
