Springboot中redisTemplate乱码或json转换问题

用RedisTemplate存入map值的时候，用rdm可视化打开，看到的是转码之后的数据，如图：

存入的方法为：

public boolean hmset(String key, Map<String, Object> map) {
    try {
        redisTemplate.opsForHash().putAll(key, map);
        return true;
    } catch (Exception e) {
        log.error(key, e);
        return false;
    }
}

问题2

存入的json字符串取出来后不能转换错误

解决办法

@Resource
private RedisConnectionFactory redisConnectionFactory;

@Bean
public RedisTemplate redisTemplate() {
    RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
    objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
    jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
    // 防止乱码
    RedisSerializer stringSerializer = new StringRedisSerializer();
    redisTemplate.setKeySerializer(stringSerializer);
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer); //解决json转换
    redisTemplate.setHashKeySerializer(stringSerializer);
    redisTemplate.setHashValueSerializer(stringSerializer);//解决哈唏值转换
    redisTemplate.afterPropertiesSet();
    return redisTemplate;
}
