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：

XML 复制代码

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

增加自定义编码

java 复制代码

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