一.在pom.xml文件中引入redis 相关包。
<dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.9.0</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency>二.在配置文件application-jdbc.yml 中加入redis的相关配置.
redis:# redis服务器地址（默认为localhost）# host: 192.168.124.34host: localhost# redis端口（默认为6379）port: 6379# redis访问密码（默认为空）password: 123456# redis连接超时时间（单位毫秒）timeout: 30000# redis数据库索引（默认为0）database: 10lettuce:pool:max-active: 100 # 连接池最大连接数（使用负值表示没有限制）max-idle: 10 # 连接池中的最大空闲连接min-idle: 5 # 连接池中的最小空闲连接max-wait: 5000ms # 连接池最大阻塞等待时间（使用负值表示没有限制）jedis:pool:enabled: truemax-idle: 100min-idle: 1auto-commit: truemax-wait: 100000max-active: 100time-between-eviction-runs: 10000三.在代码中编写redis的参数配置，数据调用，数据序列化，redis缓存配置代码
