Jackson自定义反序列化委托返回默认委托

@Override
public final T deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException {
    ObjectNode node = jp.getCodec().readTree(jp);

    T type = createType();
    //custom deserialise some fields here
    ...

    // Is there a way to delegate everything else back to Jackson?

    ObjectNode nodeToDelegate = node.get("someField");
    // delegate back to jackson and deserialise into `type`
    // nodeToDelegate can be anything - Number / Object / Array / etc.
}

p、 我确实需要自定义反序列化程序,不能使用类型批注。
