serialization

问题 I have a many to one relationship: A *<-->1 B and I want to deserialize A from a JSON having B 's primary key ( B exists in db with that primary key): { "b": 1 } I have tried the following: @Entity @Table(name = "table_a") @JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id") public class A implements Serializable { @JsonIgnore @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name = "b", unique = true, nullable = false) private B b; } and @Entity @Table(name =

问题 Is there any tool to convert xsd to c++ code. The generated code can be used for serialization and parsing the xml. It should also be run as a independent. I saw some opensource tools like CodeSynthesis but it has covered by GPL license. I am looking for a tool which will generate code that could run independently. 回答1: xsd.exe generates code for C++\CLI too. It is not added in \languages in the documentation. But when executing xsd.exe in VS CommandPrompt, in the \languages section you could

问题 My model consists in users and books. I want to nest all the books as an array of objects inside each user object, in order to show the books that each user owns. I'm trying to use marshal to nest the books as a list inside the users fields but nothing happens. In the response, there is only the array of users but no track of books and neither of an error. The idea is this: books_fields = { 'id': fields.Integer, 'type' : fields.String, 'created_at': fields.DateTime, 'user_id' : fields.Integer

问题 Let's say I have objects of type A,B and C. I have 3 Maps which contain all instances of A,B and C respectively. Internally, both A and B have Maps of C. I want to be able to store and restore the state of the application at any time. So, until today I had always serialized pyramid-like applications, where I would call serialize on the top Object, and the call would propagate to everything else. How do I deal with this situation? If I call serialize on the A map and then on the B map, aren't

问题 I want to serialize a List<AbstractClass> that contains DerivedClassA and DerivedClassB where both of these classes are derived from AbstractClass . Additionally I want to add an attribute to the element that wraps each element of the list. My desired output is something like this: <MyCustomListName foo="bar"> <DerivedClassA baseAttribute="value" attributeFromA="value"/> <DerivedClassB baseAttribute="value" attributeFromB="value"/> ... </MyCustomListName> What I have so far is this: public

问题 I'm trying to serialize a dictionary in C#. All the examples I've been able to find create XML like the following: <Dictionary> <ArrayOfEntries> <Entry> <Key>myFirstKey</Key> <Value>myFirstValue</Value> </Entry> <Entry> <Key>mySecondKey</Key> <Value>mySecondValue</Value> </Entry> </ArrayOfEntries> </Dictionary> It varies, sometimes the ArrayOfEntries node isn't necessary, but I still see the regular pattern of the dictionary's key-value pairs being stored in their own nodes. What I would like

问题 I need to do something like the following, but I need to do it without putting an attribute on or otherwise polluting the model class. An ideal solution would work via the JsonSerializerSettings , without disturbing other custom serialization. Incidentally, the below came from this question: Custom conversion of specific objects in JSON.NET public class Person { public string FirstName { get; set; } [JsonConverter(typeof(AllCapsConverter))] public string LastName { get; set; } // more

问题 I'm retrieving data from Solr in my code to get a list of Events. The results I get is formatted like so: public class SearchResults<T> where T : Result { public SearchResults() { Results = new List<T>(); } public IEnumerable<T> Results { get; set; } public int Total { get; set; } public IEnumerable<FacetField> FacetFields { get; set; } } so I get a list of results, a total count, and a list of facetfields. The list of results in this case is a list of EventResults: public class EventResult :
