use redis HashCommands.hgetall and report java.lang.UnsupportedOperationException: This type doesn't hold a Map type

See original GitHub issue

Describe the bug

the hash object that I store in redis is:

{"a":1,"b":2,"c":3}

my code:

    private final HashCommands<String, String, Integer> commands;
    
    private static final String REDIS_KEY = "my_key";

    public Demo(RedisDataSource ds) {
        commands = ds.hash(Integer.class);
    }

    public Map<String, Integer> getall(){
        return commands.hgetall(REDIS_KEY);
    }

when i use getall function, log follows:

See my PR (#28854) - not very happy with how to test on multiple Redis, but happy to get almost everything working on redis 5 (except of course, unsupported commands).

I just tried with Redis 5, and yes, they change the format. The API is designed for Redis 7.
