SpringBoot缓存技术整合SpringData Redis
首先说明一下，这里使用的是Springboot2.2.6.RELEASE版本，由于Springboot迭代很快，所以要注意版本问题。
1、SpringData Redis是属于SpringData下的一个模块。作用就是简化对于redis的操作。SpringData JPA为了简化对数据库的操作。修改pom文件添加SpringData Redis的坐标。

编写SpringData Redis的配置类，替代了之前的配置文件。

是Jedis版本问题：将Jedis改为 3.0.0版本或者2.10.1版本后即可解决。我是将Jedis2.9.0版本改为了Jedis3.0.0版本解决了问题。

提取redis的配置信息，在application.properties配置文件中新增配置信息。
1 # 最大空闲数,最后缀必须固定 2 spring.redis.jedis.pool.max-idle=10 3 # 最小空闲数,连接池中最小空闲连接 4 spring.redis.jedis.pool.min-idle=10 5 # 最大链接数,连接池最大连接数（使用负值表示没有限制） 6 spring.redis.jedis.pool.max-active=8 7 # 当池内没有可用的连接时，最大等待时间 8 spring.redis.jedis.pool.max-wait=-1ms 9 10 11 12 # 设置redis的主机 13 spring.redis.hostName=192.168.110.140 14 # 设置redis的端口号 15 spring.redis.port=6379 16 # 设置操作第一个数据库 17 spring.redis.database=0

Spring Boot整合Spring Data Redis，来进行存取Java对象。Spring Data Redis 操作实体对象。创建实体类，方便进行存储对象。

Spring Boot整合Spring Data Redis，来进行存取JSON格式Java对象。实体类直接序列化存储比实体类转换为json格式存储要大，所以也可以选择以json格式进行存储实体类对象，以 JSON 格式存储实体对象。
