Label:Application ScenariosWe want to reduce the database pressure by reducing the number of queries to the relational database through caching. In the execution of the DAO class select***() , the query***() method, the first Redis query from the cache data, if there is a direct from the Redis results, if there is no further to the database to initiate the query request fetching data.Serialization issuesTo

Usage ScenariosMany restful API interfaces now have a sign-in design, which is to request a token-based interface through a login request before initiating a formal request. After the application is successful, all subsequent payment requests are taken with this token, and the server verifies the validity of the request through this token. This token usually has an expiration date, typically a few hours.In the public platform interface, for example, the key interface should be preceded with acce

CausesRecently, the company's project to do the overdue payment needs to be automatically closed, the first thought is the spring timer (@Schedule), the results of various examples of leadership will affect performance, can only give up. Later, I would like to be able to implement based on Redis, after learning (Baidu), probably is the use of Redis keyspace no

When performing performance optimizations on Redis, you always want to read and write the Redis. However, due to the use of Spring-data-redis on the bottom of the project to operate Redis, referring to the spring official website

downloaded redis-x64-3.0.500.msi for installation. All the defaults can be taken during the installation process. After the installation has been completed may have helped you to open the Redis corresponding service, the blogger is so. View resource management as follows, instructions are open: The corresponding service has been opened, let's keep it, the following example needs to be used. If not, we

Java uses the Redis cache can use the Jedis framework, Jedis operation is simple, there is nothing complicated need to learn, the online material is many, casually look at it. Integrating spring with the Redis cache is in fact using the Jedis framework, except that spring encapsulates it in a layer and names this layer

Jedis is a Redis Java client, and spring configures the Redis connection pool as a bean."Redis.clients.jedis.JedisPool", which is a Redis connection pool for stand-alone environments.1. Maven imports the relevant package: 2, the following is the configuration of the Redis

The difference is that Redis periodically writes the updated data to disk or writes the modification to the appended record file, and on this basis implements the Master-slave (master-slave)4.
