问题原因：

版本: 3.10.6 默认使用了FstCodec 编码

3.18.0 默认编码使用：MarshallingCodec,官方已经明确不再建议使用 FstCodec编码，并且移除了Fst相关依赖

若希望继续兼容老的编码方式，进行以下步骤：

<dependency><groupId>de.ruedigermoeller</groupId><artifactId>fst</artifactId><version>2.57</version>
</dependency>

增加自定义编码

@Bean
public RedissonAutoConfigurationCustomizer redissonAutoConfigurationCustomizer(){return config -> {config.setCodec(new FstCodec());};
}
