This is not a duplicate of this question as the question here is specifically about representation of JSON strings serialized from Java in literal form in JavaScript (and it's more than double quotes one has to worry about).

问题 When I call the API, depending on the parameters, the name of the same field in the JSON returned changes. In the example below, in one case the field "user" is named "userA" or "userB". I'm using Gson but I don't want to create an object to parse the root of the JSON as I'm only interested in the list of users and I want my call to return this list only. { "apiVersion":"42" "usersA":[{ "name":"Foo", "lastname":"Bar" ... } ] "otherData":"..." } or { "apiVersion":"42" "usersB":[{ "name":"Foo",

问题 I have a class called Test with a String id field and a HashMap map like Map<String, String[]> , Map<String, ArrayList<String>> , and Map<String, HashMap> (Here the second HashMap is a <String, Integer> one) I have the following code. JsonObject jsonObject = new JsonObject(); jsonObject.addProperty("id", test.getId); Like this, I want to add the Map to this. Adding like jsonObject.addProperty("map", String.valueOf(test.getMap())); does not do the work properly as it add "(commas) to beginning

问题 I have this Json content: { "people":[ { "name":"test1", "sirname":"test2", "details":{ "social_no":1234567, "creadit_card_no":34582342309 } }, { "name":"test3", "sirname":"test4", "details":{ "social_no":12345679, "creadit_card_no":345823423090 } } ] } and according to logic this Json should have 3 POJO classes: A class that will hold the list of People, People object and a Details object. Now my question is, is it possible to deserialize this Json using Jackson or if not possible with

问题 Hi i've problem with the library Gson in a release version. In practice, in the release version of my application, using the new Gson().toJson(obj) method an incorrect string is returned. The returned string is missing some field of my object. Is it possible that the release version needs some missing options? Here are some useful information: The obj is an instance of ArrayList<MyClass> I'm using implementation 'com.google.code.gson:gson:2.8.5' I'm using Android Studio 3.5.1 MyClass is build

问题 I have the following object: public class ParameterWrapper<T> { private String type; private T value; public ParameterWrapper(String type, T value) { this.type = type; this.value = value; } public String getType() { return type; } public void setType(String type) { this.type = type; } public T getValue() { return value; } public void setValue(T value) { this.value = value; } } I am serializing it into JSON using the Gson library. When value contains a string with no spaces, it works perfectly

问题 I'm writing a JSON-style query engine in Java, and it would benefit from the ability to query a JSON document by the DOM path (like you can do in Javascript). I've checked out GSON and Jackson, but neither seem to support this. Anyone know of any alternatives, or other suggestions rather than rolling my own? e.g. //Example JSON document String json = "{ somewhere : {deep : { inside : 123 } }, anarray : [{val=1}] }"; JsonElement root = JsonParser.parse(json); //What I'd like: JsonElement node
