具体报错如下：

依赖版本

              <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
                    <version>2.4.5</version>
        </dependency>
<!--redis 里面依赖了 lettuce的版本 ，如下图-->
                <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-all</artifactId>
                        <version>5.0.0.Alpha1</version>
        </dependency>

        


 

maven xml

redis里面依赖了lettuce的版本，lettuce本身集成了netty 4.1 的版本，与项目本身集成的5.0 版本冲突。

解决办法：

1. 将本身集成的netty的版本与lettuce的版本改成一致的。

2. 去掉lettuce 改集成 jedis

   
   
   maven xml

依赖jedis版本需要查看 spring-boot-starter-data-redis 对应的jedis版本，2.4.5 默认对应 jedis 的 3.3.0版本
