springboot系列之缓存自定义CacheManager，实现json形式的数据加入redis

 @Bean
    public RedisCacheManager cacheManager(RedisConnectionFactory connectionFactory) {

        Jackson2JsonRedisSerializer<Object> redisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

        redisSerializer.setObjectMapper(objectMapper);

        RedisCacheConfiguration cacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer));

        RedisCacheManager redisCacheManager = RedisCacheManager.builder(connectionFactory).cacheDefaults(cacheConfiguration).build();

        return redisCacheManager;
    }
