redis的key值设置了生命周期后，键值失效触发事件
需要一个线程专门监听redis键值的事件
Jedis jedis=redisTest.getJedis();
for (int i = 0; i < 1; i++) {
TestThread thread= new TestThread(jedis);
thread.start();
}
在线程中配置redis的键空间通知事件：
pool.configSet("notify-keyspace-events", "Ex");
注：
默认配置是这样的：notify-keyspace-events ""
根据文档中的说明：
K Keyspace events, published with __keyspace@__ prefix.
E Keyevent events, published with __keyevent@__ prefix.
g Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
$ String commands
l List commands
s Set commands
h Hash commands
z Sorted set commands
x Expired events (events generated every time a key expires)
e Evicted events (events generated when a key is evicted for maxmemory)
A Alias for g$lshzxe, so that the "AKE" string means all the events.
在线程中添加订阅事件：pool.psubscribe(new MySubscribe(), "*");
事件需要继承redis的JedisPubSub类：
该类中有两个重要的方法：onPSubscribe(String pattern, int subscribedChannels)：订阅时触发事件
onPMessage(String pattern, String channel, String message):通知事件发生时触发事件
