问题 I am attempting to deserialize a JSON with a custom date format. It is failing, even though I have set a date format on the object mapper: SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ"); dateFormat.setTimeZone(TimeZone.getTimeZone("UTC")); mapper.setDateFormat(dateFormat); Then I attempt to deserialize the following JSON using that mapper: { "id": 11, "confirmed": false, "creationDate": "2015-04-20T22:27:41Z", "lastUpdateDate": "2015-04-20T22:27:41Z", "name":

问题 Is it possible to deserialize the following XML: <MyObject><Test>Hi hello</Test><Something><Else><With><SubItems count='5'>hello world</SubItems></With></Else></Something></MyObject> into this object: public class MyObject { public string Test { get; set; } public string Something { get; set; } } with this as expected output (this fails at the moment with XmlException: Unexpected node type Element.

问题 I am trying to serialize an object. I have the following structure: Class A{ String aField1; String aField2; B bObj; } Class B{ String bField1; String bField2; String bField3; } I am trying to serialze class A and B objects to send them to server. When I am serializing Class A object, it gives me { aField1: "abc", aField2: "def", B: { bField1: "mnp", bField2: "qrt", bField3: "xyz", } } And serializing Class B obj: { bField1: "mnp", bField2: "qrt", bField3: "xyz", } But I want Class A object

问题 I have an object called Data serialized as varbinary(MAX). Data object contains property named Source. Is there a way to make something similar: select * from content_table where Data.Source == 'Feed' I know that it is possible when XML serialization is used (XQuery). But serialization type cannot be changed in this case. 回答1: If you have used BinaryFormatter , then no, not really - at least, not without deserilizing the entire object model, which is usually not possible at the database. It

问题 I'm trying to persist images in Android. I eventually settled on the creating a wrapper object to handle serialization. I expect that it is sub-optimal. My question: How could it be done better (especially with respect to performance and not suffering image degradation from multiple serializations)? public class SerializableImage implements Serializable { private static final long serialVersionUID = 1L; private static final int NO_IMAGE = -1; private Bitmap image; public Bitmap getImage() {

问题 I have python's str dictionary representations in a database as varchars, and I want to retrieve the original python dictionaries How to have a dictionary again, based in the str representation of a dictionay? Example >>> dic = {u'key-a':u'val-a', "key-b":"val-b"} >>> dicstr = str(dic) >>> dicstr "{'key-b': 'val-b', u'key-a': u'val-a'}" In the example would be turning dicstr back into a usable python dictionary. 回答1: Use ast.literal_eval() and for such cases prefer repr() over str() , as str(

问题 I would like to disable lenient option in Jackson Deserializer to deserialize Date fields strictly. Basically, I would like the below code to throw Exception instead of parsing 33-Aug-2016 as 02-Sep-2016 . 1. Order.java package com.test.date; import java.text.SimpleDateFormat; import java.util.Date; import com.fasterxml.jackson.annotation.JsonFormat; public class Order { @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MMM-yyyy") private Date orderDate; public Date getOrderDate() {
