[FIXED] How can I serialize Jackson's JsonNode object?

Issue

I am replacing an in-house caching system with memcached but memcached client cannot cache the JsonNode objects since they don't implement Serializable. Is there any way you can achieve serializing a JsonNode object? Does Jackson provide Serializable equivalent of this class?

Solution

JSON is best serialized by writing it out as bytes. In Jackson, it is done using ObjectMapper, for example by:

byte[] raw = objectMapper.writeValueAsBytes(root);

MemCache does not really need Serializable since it's all raw bytes; although Java clients may try to be helpful and handle serialization.
