gson

问题 I am fetching data from API provided by our Backend team. One of the keys data sometimes contains JSONObject and sometimes it contains JSONArray . I am using GSON to parse the response and it is throwing an exception because of this. I tried the solution given in this thread but it's not working in my case. How to dynamically handle json response array/object using Gson POJO (EntityDetailResponseV2): package com.tf.eros.faythTv.objects.entityDetail; import com.google.gson.Gson; import com

问题 I'm using Retrofit 2 in Android Studio to get stop information in JSON form from the CUMTD api for stops by search and for some reason the connection keeps on failing, are the query parameters and everything else correct, i used to the JSON to pojo converter for the model class so it should be correct or is it something from main activity? Heres the URL I'm trying to connect to https://developer.cumtd.com/api/v2.2/json/GetStopsBySearch?key=b7cd7d8c64b24b4f8415aeb57d6f7f74&query=transit

问题 I'm trying to learn MVVM architecture on parse Json into a Recyclerview in MVVM using coroutines. But I'm getting error on BlogRepository class. My Json file looks like this: [ { "id": 1, "name": "potter", "img": "https://images.example.com/potter.jpg" }, { …} ] I have created data class as below: @JsonClass(generateAdapter = true) class ABCCharacters ( @Json(name = "id") val char_id: Int, @Json(name = "name") val name: String? = null, @Json(name = "img") val img: String ) Then the

问题 In my code, I need to add an org.json.JSONObject to another object which is serialized using gson.toJson . However, when this object is serialized, the values in the JSONObject are nested into a map key by gson itself. For example, public class New { private static final Gson gson = new GsonBuilder().disableHtmlEscaping().create(); public static void something(User user) throws Exception { try { ObjectWriter ow = new ObjectMapper().writer(); String json = ow.writeValueAsString(user);

问题 I'd like to execute jmeter tests from maven using groovy scripts, but I got the error below. For setting up jmeter and maven I did what is described here. Shall I package my groovy functions and entities into a jar and copy into jmeter's lib directory and only put those groovy scripts next to the jmx file which contains the sampler code? 2019-06-22 17:40:17,714 INFO o.a.j.s.SampleResult: sampleresult.useNanoTime=true 2019-06-22 17:40:17,714 INFO o.a.j.s.SampleResult: sampleresult

问题 I'm trying to get AdMob ID's into my app from JsonData so that I can change it in the future. My Vision: JSON file will be uploaded into my server and a link of it will be inside the app. The AdMob ID found inside the json file should be used inside the app adUnitID. So far, I have made this: String jsonToProcess = "https://drive.google.com/uc?id=113RUepiYecy5pBwj-t4BtBXwlQwgf-dU"; String interstialAd = new JsonParser().parse(jsonToProcess).getAsJsonObject() .get("response").getAsJsonObject()

问题 If I have serialized a class into json, which contains dates, using gson, how can I use the value of the json to insert into my h2 or MySQL database using MyBatis? The json below is constructed using the following code: Bean bean = new Bean(); bean.setIsPublished(true); bean.setPublicationDate(Calendar.getInstance().getTime()); Gson gson = new GsonBuilder().setDateFormat("yyyy-mm-dd-hh:mm:ss").create(); String json = gson.toJson(bean); Which makes json: { "isPublished":true, "publicationDate"

问题 Currently, I have a lot of occurences in my code that read as follows: result = new Gson().fromJson(someString, ResultContainer.class); Should I share the GSON object over all those places? If so, per object or static per class (potentially even superclass?) I am asking mainly because if sharing the reference statically is fine, then why isn't the Gson object static in the first place? Unless one uses fancy custom serialization rules, the method above pretty much covers what one would want

问题 I have a json string like this: { "d": { "results": [ { "__metadata": { "uri": "http://localhost:2000", "key_fields": "Accountnum", "rows_affected": 0, "last_autoinc": 0 }, "Accountnum": "9999999", "workphone": null, "name": "Smith", "address": "33 Main St", "city": "Anytown", "state": "FL", "zip": "33333", } ] } } and I tried to deserialize it according to diffrent questions here on stackoverflow, but I can't get it right. Here is what I did I created a class, I only need the accountnum and

问题 I have this JSON that I retrieved using Bing-Search-API. Now, I'm not sure how to access the nested elements using GSON. I already made the source files for the JSON Structure Data. If I do this: Gson gson = new Gson(); JsonParser parser = new JsonParser(); JsonArray Jarray = parser.parse(jsonText).getAsJsonArray(); It is going to throw me that is not a JsonArray , so If I change it to JsonObject , how can I retrieve the String MediaUrl from Results.java? Thank you 回答1: Based on the javadoc
