使用 RedisSaver 作为 Checkpointer，Redis 会写入乱码，同一 threadId 再次调用，就会报错：class java.util.HashMap cannot be cast to class org.springframework.ai.chat.messages.Message

代码如下：

RedisSaver redisSaver = new RedisSaver(redissonClient);
ReactAgent agent = ReactAgent.builder()
              .name("simpleAgent")
              .model(chatModel)
              .systemPrompt("You are a helpful assistant.")
              .tools(timeToolCallback)
              .saver(redisSaver)
              .build();

RunnableConfig config = RunnableConfig.builder()
        .threadId("12336560001")
        .build();
return agent.call(content, config).getText();

Redis 中存入的数据如下图：

再次调用该接口，报错如下：

同样，使用 MongoSaver 作为 Checkpointer，虽然不会写入特殊字符，但再次调用仍会报错：class java.util.HashMap cannot be cast to class org.springframework.ai.chat.messages.Message
