redisTemplate获取redis的set类型和hash类型报错

查明原因是序列化转换的问题，每个类型都有对应的序列化转换set和hash如下：

redisTemplate.setValueSerializer(new StringRedisSerializer());
Set<String> users =redisTemplate.opsForSet().members("xxxxx");

// 获取 Hash 数据
RedisSerializer redisSerializer = new RedisSerializer() {
    @Override
    public byte[] serialize(Object o) throws SerializationException {
        return JSON.toJSONBytes(o);
    }

    @Override
    public Object deserialize(byte[] bytes) throws SerializationException {
        String obj = new String(bytes);
        return obj;
    }
};
redisTemplate.setHashValueSerializer(redisSerializer);
Map<String,String> userMap = redisTemplate.opsForHash().entries("xxxxx");
