问题 I want to serialize a Map with Jackson. The Date should be serialized as a timestamp, like all my other dates. The following code renders the keys in the form "Tue Mar 11 00:00:00 CET 1952" (which is Date.toString()) instead of the timestamp. Map<Date, String> myMap = new HashMap<Date, String>(); ... ObjectMapper.writeValue(myMap) I assume this is because of type erasure and jackson doesn't know at runtime that the key is a Date. But I didn't find a way to pass a TypeReference to any

问题 I'm trying to use JSON.NET as a default serializer in WebAPI 2 stack. I've implemented JsonMediaTypeFormatter, in which I've used JSON.NET serializer for serialize/deserialize data and created JsonContentNegotiator for using this media type formatter. All works fine except OData querying - if I add [Queryable] metadata ot action method, then response object doesn't contains any metadata information, only list of entities. Small example. My action method: [Queryable] public async Task

问题 <ROOT> <A> <B>TESTING</B> </A> </ROOT> XSL: <xsl:variable name="nodestring" select="//A"/> <xsl:value-of select="$nodestring"/> I am trying to convert XML nodeset to string using XSL. Any thoughts? 回答1: You need to serialize the nodes.

问题 How can I achieve the following JSON representation of Id class when used in another class? class Car { public StringId Id { get; set; } public string Name { get; set; } } class StringId { public string Value { get; set; } } // --------------------------------------------- // Desired representation { "Id": "someId", "Name": "Ford" } // Default (undesired) representation { "Id" : { "Value": "someId" }, "Name": "Ford" } 回答1: You could add a TypeConverter for StringId . Json.NET will pick up the
