一样的实现 about shiro-redis

[alexxiyang]

@DR-YangLong 您好，关于单点问题，是否考虑过使用Redis Sentinel的Automatic failover?

[DR-YangLong]

我目前的环境使用redis的单机，想过主备切换，但是app端还是需要开发，开始想的解决方法是使用zookeeper实现自动切换，对外提供一个访问地址，现在换了工作，项目小，redis没有继续使用

[DR-YangLong]

我测试在支持JDK原生序列化的情况下，fst的速度是最快的，fastjson慢到不可接受，fastjson不太适合对象的序列化，另外我参考了oschina的kryo的池式实现写了差不多的序列化器，但是性能还是没有fst好。
