问题1

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;

}
