deserialization

问题 class Parent implements Serializable{ ........ } class Child extends Parent{ private void writeObject(ObjectOutputStream oos) throws IOException { throw new NotSerializableException(); } private void readObject(ObjectOutputStream oos) throws IOException { throw new NotSerializableException(); } } The above code shows how child avoids Serializable if the parent is already implemented Serializable . It seems to be a bad design and confusing at some points, so I am wondering in what circumstance

问题 I have a JSON string that contains an array and it is unable to be deserialized. I would like to split so that I can access a list of products and their codes and quantities, each time I try it crashes. The Json string is returned like so: { "transaction_id": "88", "store_id": "3", "cashier_id": null, "loyalty_account": null, "transaction_time": "1382027452", "total_amount": "99.45", "items": { "1239219274": "1", "3929384913": "1" }, "payments": { "cc": "99.45" } } I would like it to be

问题 I have a problem with proguard config in Android Project. I'm using Genson to parse incoming JSON data. It is fast and there is no need for extra configuration or deserializers, because on the Server-side there is also Genson. Everything works fine in debug mode, but in release, with proguard it doesn't. Unfortunately I have some error during runtime: FATAL EXCEPTION: main Process: com.es.mobile.meedy, PID: 16650 java.lang.UnsupportedOperationException: Couldn't find parameter at 0 from type

问题 Here is the method that I want to refactor: public static List<ComponentPOCO> parseJsonComponentFromString(String fileContents){ try { ObjectMapper mapper = new ObjectMapper() .enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY) .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); List<ComponentPOCO> component = mapper.readValue(fileContents, new TypeReference<List<ComponentPOCO>>() {}); return component; } catch (IOException e) { e.printStackTrace(); } return null; }

问题 How do I parse this particular json string with Gson in Java? {"orders":[{"oid":"347","status":"1"},{"oid":"348","status":"1"}],"a":14.15,"b":0} What is problematic is the orders list. I suppose one has to use a "type token" parameter to Gson.parse(json,type-toke), but it is not clear to me how this can be done. 回答1: You have to create java types that it can be mapped to. So, you would have something like this. public class Result { private List<Order> orders; private Number a; private Number

问题 I have an xml document, where i serialize data dinamically, appending new data if i have a new request. The object properties i serialize are like this [XmlRoot("LogRecords")] public class LogRecord { public string Message { get; set; } public DateTime SendTime { get; set; } public string Sender { get; set; } public string Recipient { get; set; } } Serializing is done in this way : var stringwriter = new StringWriter(); var serializer = new XmlSerializer(object.GetType()); serializer

问题 I'm sending a json string as an http request and recieving a json string in the response. I've created my own classes to serialize from and deserialize into. They look as follows: On the Request side - public class RequestHead { public string source {get; set;} public string dest {get; set;} } public class RequestBody { private List<string> id {get; set;} public bool direction {get; set;} public RequestBody() { this.id = new List<string>(); } } public class RequestObj { public RequestHead

问题 I was trying to implement parsing a JSON response as shown here for my Windows Phone 7 project in C#. But I am stuck with a compilation error as "The type or namespace name 'Serializable' could not be found (are you missing a using directive or an assembly reference?)"
