1：pom.xml添加依赖

<dependency><groupId>org.redisson</groupId><artifactId>redisson-spring-boot-starter</artifactId><version>3.21.1</version>
</dependency>

2-1：方法一：读取默认yml配置

# redis配置
spring:redis:database: 0host: 127.0.0.1password: 123456port: 6379

2-2：redisson.yml文件的方式

spring:redis:redisson:file: classpath:redisson.yml

2-3：redisson.yml

# 单节点配置
singleServerConfig:# 数据库编号database: 0# 节点地址address: redis://127.0.0.1:6379# 密码password: 123456

# 集群模式
clusterServersConfig:# 集群节点地址nodeAddresses:- "redis://127.0.0.1:16379"- "redis://127.0.0.1:26379"- "redis://127.0.0.1:36379"password: 123456
#Redis集群不支持多个数据库的概念，默认只有一个数据库，即db 0，所以这里是没有database这个参数的

3-1：方法二：自定义yml配置

spring:redis:# redisson配置redisson:# 如果该值为false，系统将不会创建RedissionClient的bean。enabled: true# mode的可用值为，single/cluster/sentinel/master-slavemode: single# single: 单机模式#   address: redis://localhost:6379# cluster: 集群模式#   每个节点逗号分隔，同时每个节点前必须以redis://开头。#   address: redis://localhost:6379,redis://localhost:6378,...# sentinel:#   每个节点逗号分隔，同时每个节点前必须以redis://开头。#   address: redis://localhost:6379,redis://localhost:6378,...# master-slave:#   每个节点逗号分隔，第一个为主节点，其余为从节点。同时每个节点前必须以redis://开头。#   address: redis://localhost:16379,redis://localhost:26379address: redis://127.0.0.1:6379# redis 密码，空可以不填。password: 123456database: 0

3-2：RedissonConfig自定义配置类
