## 项目场景： ##

`Spring Boot集成Redis集群`

单节点配置：

spring.redis.database = 0
    spring.redis.host = 127.0.0.1
    spring.redis.password = test@redis
    spring.redis.port = 8003
    # 连接超时时间 单位 ms（毫秒）
    spring.redis.timeout = 3000

集群配置：

#集群配置
    spring.redis.cluster.nodes = 127.0.0.1:8001,127.0.0.1:8002
    spring.redis.database = 0
    spring.redis.password = test@redis
    # 连接超时时间 单位 ms（毫秒）
    spring.redis.timeout = 3000

maven依赖

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

## 问题描述 ##

> Redis exception; nested exception is io.lettuce.core.RedisException: java.lang.UnsupportedOperationException

完整错误 ：

        at org.springframework.data.redis.core.RedisTemplate.delete(RedisTemplate.java:709)

--------------------

## 原因分析： ##

> 线上部署的redis版本较高，而spring boot引入的版本较低，版本不一致导致的问题

--------------------

## 解决方案： ##

> lettuce排除低版本，引入高版本
