优化：基于阿里巴巴 Java 开发手册(黄山版)优化常量及包命名

1.编程规约>常量定义>第4条：
【推荐】不要使用一个常量类维护所有常量，要按常量功能进行归类，分开维护。
说明：大而全的常量类，杂乱无章，使用查找功能才能定位到要修改的常量，不利于理解，也不利于维护。
正例：缓存相关常量放在类 CacheConsts 下；系统配置相关常量放在类 SystemConfigConsts 下。
2.编程规约>常量定义>第5条：
【推荐】常量的复用层次有五层：跨应用共享常量、应用内共享常量、子工程内共享常量、包内共享常
量、类内共享常量。
  1）跨应用共享常量：放置在二方库中，通常是 client.jar 中的 constant 目录下。
  2）应用内共享常量：放置在一方库中，通常是子模块中的 constant 目录下。
  反例：易懂常量也要统一定义成应用内共享常量，两个程序员在两个类中分别定义了表示“是”的常量：
  类 A 中：public static final String YES = "yes";
  类 B 中：public static final String YES = "y";
  A.YES.equals(B.YES)，预期是 true，但实际返回为 false，导致线上问题。
  3）子工程内部共享常量：即在当前子工程的 constant 目录下。
  4）包内共享常量：即在当前包下单独的 constant 目录下。
  5）类内共享常量：直接在类内部 private static final 定义。
