Spring AOP + Redis Cache database Query

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:

Spring Redis Cache @Cacheable large concurrent return Null__redis

Problem Description Recently we used spring cache + Redis to do caching. Under high concurrency the @cacheable annotation returns a null content. Look at the source code, in the use of annotations to get the cache, the Rediscache get method will first determine whether the key exists, and then to get the value. There's a copper leak, and when thread 1 judges that the key is there, then the key expires, and

When Spring data operates Redis, it finds that the key value appears \XAC\XED\X00\X05T\X00\TB
