参数名称参数解释
redis.max.total最大连接数
redis.max.idle最大空闲连接数，在jedispool中最大的idle状态(空闲的)的jedis实例的个数
redis.min.idle最小空闲连接数，在jedispool中最小的idle状态(空闲的)的jedis实例的个数
redis.test.borrow在取连接时测试连接的可用性，在borrow一个jedis实例的时候，
是否要进行验证操作，如果赋值true。则得到的jedis实例肯定是可以用的
redis.test.return再还连接时不测试连接的可用性，
在return一个jedis实例的时候，是否要进行验证操作，如果赋值true。则放回jedispool的jedis实例肯定是可以用的。
redis.ipredis服务端ip
redis.portredis服务端port
redis.server.timeoutredis连接超时时间
redis.lock.timeout锁超时时间
