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。

编写测试代码，测试整合环境。
1 package com.bie.springboot; 2 3 import org.junit.jupiter.api.Test; 4 import org.junit.runner.RunWith; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.boot.test.context.SpringBootTest; 7 import org.springframework.data.redis.core.RedisTemplate; 8 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 9 10 @RunWith(SpringJUnit4ClassRunner.class) 11 @SpringBootTest(classes = SpringdataRedisApplication.class) 12 class SpringdataRedisApplicationTests { 13 14 @Autowired 15 private RedisTemplate<String, Object> redisTemplate; 16 17 /*** 添加一个字符串 */ 18 @Test 19 public void testSet() { 20 this.redisTemplate.opsForValue().set("key", "我想要学好springboot"); 21 } 22 23 /*** 获取一个字符串 */ 24 @Test 25 public void testGet() { 26 String value = (String) this.redisTemplate.opsForValue().get("key"); 27 System.out.println(value); 28 } 29 30 }
如果报了下面所示的错误，如下所示：

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。
1 <!-- jedis是操作redis的工具依赖包 --> 2 <dependency> 3 <groupId>redis.clients</groupId> 4 <artifactId>jedis</artifactId> 5 <version>3.0.0</version> 6 </dependency>
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
修改配置类，配置属性在application.properties进行设置。

使用上面的测试类进行测试，观察控制台，可以看出一些配置信息。
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。

使用测试类，开始进行测试。

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。
