Java Spring中带有json:map键序列化的Redis缓存

希望你能帮我

我使用SpringBoot1.3.0M5和Redis作为缓存实现，通过注释

    @Bean
// redis template used for caching
public RedisTemplate<String, Object> cacheRedisTemplate()    {
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate();
    redisTemplate.setKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashKeySerializer(jackson2JsonRedisSerializer());
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer());
    redisTemplate.setConnectionFactory(connectionFactory());
    return redisTemplate;
}

@Bean
public Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer() {
    final Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
    final ObjectMapper objectMapper = Jackson2ObjectMapperBuilder
            .json()
            .build();
    objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
    objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
    jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
    return jackson2JsonRedisSerializer;
}

这在第一次工作时是有效的，但在redis缓存它之后，整数键被序列化为字符串，然后反序列化为字符串，因此它不会再次工作，因为键将是“1”而不是1

我尝试过使用@JsonDeserialize（keyAs=Integer.class），也尝试过注册objectMapper模块，但都不起作用

非常感谢。

嗨，你解决了吗？嗨，你解决了吗？

 @Cacheable(value = "forecasts", key = "'forecasts'", cacheManager = "forecastCacheManager")
public Map<Integer, Forecast> retrieveForecasts() {
  < retrieve data >

  return stream.collect(Collectors
    .<Forecast, Integer, Forecast>toMap(o -> o.getGame(), o -> o));
 }

forecastMap.get(1)
