Jedis operation Redis and spring integration in Java

Redis is a key-value storage system. It supports storing more value types, including string (string), list (linked list), set (set), and Zset (ordered collections). These data types support Push/pop, Add/remove, and intersection-set and difference sets, and richer operations, and these operations are atomic. Based on this, Redis supports sorting in a variety of different ways. To ensure efficiency, the data is cached in memory. Redis periodically writes the updated data to disk or writes the modified operation to the appended record file, and Master-slave (Master-Slave) synchronization is implemented on this basis. The following is an integrated standalone and clustered version of Jedis operations for Redis and spring:

First, you are ready to click the version and the cluster version of how to: Jedisclientsingle, Jedisclientcluster
