Interface JSONSerialisation
-
public interface JSONSerialisation
Responsible for serialising and deserialising objects to and from JSON. Note: This serialisation mechanism uses Jackson's ability to detect fields in an object to serialise. It does not use getters and setters (JavaBean based) which is the default. See the configuration that is defined in the constructor for more details. Note: Important caveat, JSON does not handle Maps with keys that are not strings (Enums, Objects etc). This is covered here http://stackoverflow.com/questions/11246748/deserializing-non-string-map-keys-with-jackson?lq=1 the recommendation is to switch the map to use strings as keys and convert accordingly. If necessary it is possible to implement custom KeySerializer/KeyDeserializer implementations to ensure the map keys are correctly handled during serialisation and deserialisation. The default KeySerializer implementation calls toString on the key object, which may be suitable in certain cases. Note: Another Important caveat, It appears that Jackson basically handles poorly any Object that is not a String, Integer, Map or a List. Based on this I cannot recommend this class as a general purpose Object to JSON serialisation class, unless the caller makes extra effort to ensure that their objects are being serialised following the above guidelines.
