The recent need to design a distributed scheduled task, in theory, Quartz has provided a complete set of distributed scheduled tasks of the solution, but because the system currently has a JMS cluster and Redis Sentinel cluster, if you want to the existing architecture, Implementation of a simple distributed timing task, how to do it. The overall architecture plan is as follows: Redis cluster: Provides d

In a distributed environment, how to support the PC, APP (iOS, Android) and other multi-terminal session sharing, which is the solution that all companies need, with the traditional session way to solve, I think it is out, we can find a common solution, For example, using traditional CAs to achieve SSO single sign-on between multiple systems or using OAuth for third-party login scenarios? Let's talk about it today. Using Spring Interceptor Interceptor

Redis is used as a cache in the most recent project, and the database is MongoDB. Project uses spring and everything works without introducing Redis, but add in Pom.xml: When a dependency on Redis is introduced, no other action has been done at this time.

The Redis cache data used in Spring can be directly manipulated via redistemplate or @cacheable annotations (as described in another article: Spring cachable key definition and application). Regardless of the method used, the key, value is serialized into a byte array, or a string is saved. Redistemplate source code can be seen, its serialization is through a ser

Redis has created a new way of storing data. When using redis, we don't have to focus on how to put elephants in the refrigerator in the face of monotonous databases, instead, redis uses flexible data structures and data operations to build different refrigerators for different elephants.
