deserialization

问题 Similar to this question I want to ignore a field in my java POJO . However, I want to always ignore the field whether or not it is null.

问题 I want to deserialize a json string that containts a null value in Java. I want to deserialize the object to a Properties object. The json string is something like: {"prop1":null, "propr2":"fancy value"} When I deserialize using String json = // new Gson().fromJson(json, Properties.class); I get a null pointer exception because of the Hastable that into the Properties object.

问题 I use JavaScript.Serializer.Deserializer to deserialize a complex JSON object, as below: { "name": "rule 1", "enabled": true, "conditions": [{ "type": "time", "time": "17:23:10", "days": "125" }, { "type": "sensor", "uid": "10.2.0.1", "setpoint1": 12, "setpoint2": 18, "criterion": 1 }, { "type": "sensor", "uid": "10.3.0.1", "setpoint1": 12, "setpoint2": 18, "criterion": 2 }], "actions": { "period": 100, "single": false, "act": [{ "type": "on", "uid": "10.1.0.1" }, { "type": "sms", "message":

问题 I want to ask about serialize/deserialize object with binary formatter. well i'm trying to deserialize object in FileStream that contain many objects that has been serialized one by one. The size of an object is too big to be saved in process memmory that's why i don't pack all of objects in one such as: List because they are too big in process memory So i serialize as much as needed in many times. with this way it won't take many process memmory because i just process one object alternately

问题 Dear folks I need you advice. I'm, trying to implement custom Jackson deserializer for maps but having difficulties with it. As an input data I have the following json: { "someMap": { "one_value": "1", "another_value: "2" }, "anotherMap": "{\"100000000\": 360000,\"100000048\": 172800,\"100000036\": 129600,\"100000024\": 86400,\"100000012\": 43200}" } As you can see in the second case it has json map inside node value(I'm doing it in that way by intention. Because I want to replace the value

问题 Working on deserializing a dynamic JSON file which could contain 2 separate classes and I won't know which type of data will be in the array. The problem is, I deserialize the root object to type "Base", "subtests" objects are deserialized to "Subtest", but the "subtests" array could be of type "Base" or of type "Subtest". QUESTION: How would I go about programatically determining that if the object contains "subtest", I deserialize to Base, and if it doesn't, it should deserialize to

问题 I have an incoming xml from Recurly service with list of transactions. Sometimes it's empty and looks like this: <transactions type="array"> </transactions> I need to deserialize this using Jackson. I've tried next mapping @XmlRootElement(name = "transactions") public class TransactionObjectListResponse extends ArrayList<TransactionObjectResponse> { } where TransactionObjectResponse class for each transaction. It works fine for non-empty collections, but fails when no transactions came. Next

问题 I've managed to find a solution without removing the paths from the keys. Thanks for the help guys, and also pointing out problems, I really appreciate it! :) Loaded the Json to a string, deserialized it into a dynamic, ran a foreach through it, and added to a List with ResFiles in it. static void loadJson() { List<ResFile> fileList = new List<ResFile>(); string jsonString = File.ReadAllText(jsonPath); dynamic files = JsonConvert.DeserializeObject(jsonString); foreach (var f in files.objects)
