Spring provides specialized support for Redis: Spring-data-redis. In addition, similar to the following:I think most people are concerned about Spring-data-hadoop, Spring-data-mongodb, Spring
Spring boot also encapsulates the NoSQL database by automating the usual database support.About RedisRedis is the most widely used memory data store in the industry today. Supports a richer data structure than memcached,redis, such as hashes, lists, sets, etc., while supporting data persistence. In addition to this, Redis also provides some features of the class
With the latest Jedis-2.6.2.jar This bag, this is a little different from the previous one.

. The difference is that Redis periodically writes the updated data to disk or writes the modified operation to the appended record file, and implements the Master-slave (Master-Slave) 4, the Code implementation 1), The configured file (properties) configures the parameters that are often changed into separate propertis to facilitate subsequent modifications redis.propertiesredis.hostname=127.0.0.1redis.port= 6379redis.timeout=15000redis.usepool=truer
before and after the intercepted method, for example, I go to redis before querying, and find out that no database is checked, I also need to return to the result set to Redis, So that's a big part of it.4.

Spring AOP + Redis cache database query, aopredisApplication scenarios
We hope to cache the database query results to Redis so that the results can be directly obtained from redis for the second query, thus reducing the number of database reads and writes.Solutions to problems to be solved avoid dirty reading
The query
There is an example of spring-based Redis, which gets Jedis instances from jedisconnectionfactory . The rest of the section ignores only Redisservice, so there are many problems with getting Jedis instances.This way, each new connection is innovated without closing the connection. The Redis connection will be full soon when there is a lot of operation. reported
