JAVA实现redis超时失效key 的监听触发详解编程语言

 1 # K    键空间通知，以__keyspace@<db>__为前缀   
 2 # E    键事件通知，以__keysevent@<db>__为前缀   
 3 # g    del , expipre , rename 等类型无关的通用命令的通知, ...   
 4 # $    String命令   
 5 # l    List命令   
 6 # s    Set命令   
 7 # h    Hash命令   
 8 # z    有序集合命令   
 9 # x    过期事件（每次key过期时生成）   
10 # e    驱逐事件（当key在内存满了被清除时生成）   
11 # A    g$lshzxe的别名，因此”AKE”意味着所有的事件
