本教程主要詳細講解Spring Data Redis,它向Redis提供Spring Data平臺的抽象.php

Redis由基於key/value庫的數據結構存數，以持久保存數據，並可用做數據庫，緩存，消息代理等。java

基礎環境

技術	版本
Java	1.8+
SpringBoot	2.x.x
DataJPA	2.x.x
Jedis	2.9.x

配置支持Redis

在resources資源目錄下建立一個application.properties的配置文件,內容以下

spring.redis.host=localhost
spring.redis.port=6379
spring.redis.database=0
spring.redis.jedis.pool.max-active=8
spring.redis.jedis.pool.max-wait=1ms
spring.redis.lettuce.pool.max-active=8
spring.redis.jedis.pool.min-idle=0

操做Redis數據

在/src/main/java/com/edurt/sli/slidr目錄下建立model目錄,並在該目錄下新建RedisModel文件

@RedisHash爲每一個數據庫建立域類的空子類。github

@Id註解的屬性和被命名爲id的屬性會被看成標識屬性web

在/src/main/java/com/edurt/sli/slidr目錄下建立repository目錄,並在該目錄下新建RedisSupport文件
