Mode of operation

There are several ways for spring to operate redis. Here are the two most commonly used ways, both of which are synchronized.

RedisTemplate

Redis Repository

The above is the result of the encapsulation of the redis client by spring. The redis client is divided into different dependencies according to different spring versions. The commonly used ones are jedis and lettuce.

Spring also supports responsive access to redis server since version 5.0, but it may not be necessary. It is mainly supported by encapsulating lettuce as a redis client. Jedis does not support reactive access to redis server.

Introduction to demo function

Use spring-boot-starter-data-redis:2.1.2

Easy to operate redis database by using Redis Repository feature

Object storage, key-value

Set obsolete time

Operation flow

A redis server, version > = 2.8,

A springboot with web,lombok,redis and other components, springboot version > 2.0

Persistent object domain

Dao layer, repository

Source code reading

View RedisConfig

@ Configuration represents the configuration class

@ EnableRedisRepositories means to enable the Redis Repository feature

RedisConnectionFactory is the connection pool for redis. Configuring RedisTemplate requires

RedisTemplate as a dependency on Redis Repository

Check the person class in domain

@ RedisHash (people) identifies the prefix of the key; @ Id identifies this field as the unique identity of the people and the second half of the key.

@ TimeToLive indicates the expiration time. Once expired, the object of the redis corresponding to the key will be removed.

View AppController

Just look at the main logic, which is just an entrance to the web interface.

It contains the use of curd for operating redis repository and setting the expiration time
