In view of redis list, hash, set, string and other types of operations, many people are familiar with the use of, a brief introduction to dynamic parameter modification, master-slave switchover, persistent settings, system information monitoring.
Redis Chinese document, there is a detailed description of the console operation, http://redis.readthedocs.org/en/latest/index.html
The following content is the java api application.
