Hello!
I'm trying to serialize an ObjectNode value that contains nested ObjectNode values. What is the correct way to have Jackson serialize the keys in alphabetical order? Bear in mind that I don't actually know the structure of the ObjectNodes before I serialize them; only that they're effectively arbitrarily nested key/value structures. I've seen the Stack Overflow answers: https://stackoverflow.com/questions/27577701/jackson-objectmapper-specify-serialization-order-of-object-properties ... And they're either not relevant to my problem (specifying annotations on classes used for deserialization when I'm dealing with ObjectNodes I didn't deserialize), or specify various combinations of the MapperFeature.SORT_PROPERTIES_ALPHABETICALLY, or SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS flags, which don't appear to have any effect. My code essentially looks like this: ``` fun canonicalize( objectNode: ObjectNode, outputStream: OutputStream ) { val mapper = ObjectMapper() mapper.configure(SerializationFeature.INDENT_OUTPUT, false) mapper.configure(MapperFeature.SORT_PROPERTIES_ALPHABETICALLY, true) mapper.configure(SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS, true) mapper.writeValue(outputStream, objectNode) } ``` The data written to the output stream does _not_ have the keys sorted in alphabetical order. Any help would be appreciated! -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
