Spring and redis correctly obtain the Jedis instance from jedisConnectionFactory, redisjedis This example of spring combined with redis is circulating on the Internet to obtain a Jedis instance from jedisConnectionFactory. Others ignore the RedisService only, so there are many problems in obtaining the jedis instance.I

This is a tutorial to implement session sharing with spring boot + redis.In the spring boot documentation, tell us to add @enableredishttpsession to enable spring session support, which is configured as follows:Java code @Configuration @EnableRedisHttpSession Public class Redissessionconfig { } @enableredishttpsession This annotation is

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

saying:Any problem in computer science can is solved by anther layer of indirection.CacheTogether we can see that the cache is a kind of agent in a sense, through the advantages of one aspect of itself to compensate for the limitations of the actual response, in theory, the trade-offs between time and space.Several common caches are listed below1, Database CacheReduce file system read and write times and program response time by caching query statements into memory2, application cacheReduce dat

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

However, these difficulties can be overcome, so we still choose JSON as a serialized storage method.Where is the code written?No doubt it AOP 's time to play. In our case, the persistence framework uses MyBatis that, so our task is to intercept Mapper the invocation of the interface method by writing the Around(环绕通知) following logic:
