How can I serialize Jackson's JsonNode object?

问题

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?

回答1:

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.
