解决SpringBoot2.0 集成Redis @Cacheable乱码的情况

@Configuration
public class Config  extends CachingConfigurerSupport {

    @Bean(name="redisTemplate")
    public RedisTemplate redisTemplate(RedisConnectionFactory factory) {

        RedisTemplate template = new RedisTemplate<>();

        RedisSerializer redisSerializer = new StringRedisSerializer();

        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);

        template.setConnectionFactory(factory);
        //key序列化方式
        template.setKeySerializer(redisSerializer);
        //value序列化
        template.setValueSerializer(jackson2JsonRedisSerializer);
        //value hashmap序列化
        template.setHashValueSerializer(jackson2JsonRedisSerializer);

        return template;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        RedisSerializer redisSerializer = new StringRedisSerializer();
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        // 配置序列化
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig();
        RedisCacheConfiguration redisCacheConfiguration = config.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer));

        RedisCacheManager cacheManager = RedisCacheManager.builder(factory)
                .cacheDefaults(redisCacheConfiguration)
                .build();
        return cacheManager;
    }
}
