问题 I have a very simple JSON with reviews for products, like: { "reviewerID": "A2XVJBSRI3SWDI", "asin": "0000031887", "reviewerName": "abigail", "helpful": [0, 0], "unixReviewTime": 1383523200, "reviewText": "Perfect red tutu for the price.

问题 I have some JSON that I am deserializing using Gson. { "resp": { "posts": [ { ... "public": true, ... }] } My problem is that public is a Java keyword, so how would I make a field in my class that correlates with the public field in the JSON? 回答1: You could use a different name for your field, using gson's Field Naming Support. public class Post { @SerializedName("public") private boolean isPublic; ... } 回答2: Worth a quick note that you need to include gson.annotations or SerializedName for

问题 I need to deserialize json which is an array of date/long values. Here is an example of the returned JSON: [{"2011-04-30T00:00:00-07:00":100}, {"2011-04-29T00:00:00-07:00":200}] Using GSON I am able to deserialize this to a List<Map<Date,String>> , but would like to be able to convert it to a List<MyCustomClass> similar to: public class MyCustomClass() { Date date; Long value; } I cannot seem to find a way to instruct GSON to map the key/value of the JSON map to the date/value fields in my

问题 I have been looking around for examples related to converting JSON strings to Java object but haven't found any good examples. The one I found was really basic once and not really dealing with complex JSON strings. I am making an app to translate strings from english to different languages using google translate api. Google's response upon query is...foolowing text is formatted in JSON, {"data":{"translations":[{"translatedText":"Bonjour tout le monde"}]}} my approach so far is using GSON API

问题 I would like to generate a JSON String from my object: Gson gson = new Gson(); String json = gson.toJson(item); Everytime I try to do this, I get this error: 14:46:40,236 ERROR [[BomItemToJSON]] Servlet.service() for servlet BomItemToJSON threw exception java.lang.StackOverflowError at com.google.gson.stream.JsonWriter.string(JsonWriter.java:473) at com.google.gson.stream.JsonWriter.writeDeferredName(JsonWriter.java:347) at com.google.gson.stream.JsonWriter.value(JsonWriter.java:440) at com

问题 So I'm using GSON to parse JSON from an API and am stuck as to how to have it parse the dynamic fields in the data. Here is an example of the JSON data returned on a query: { - 30655845: { id: "30655845" name: "testdata description: "" latitude: "38" longitude: "-122" altitude: "0" thumbnailURL: http://someimage.com/url.jpg distance: 9566.6344386665 } - 28688744: { id: "28688744" name: "testdata2" description: "" latitude: "38" longitude: "-122" altitude: "0" thumbnailURL: http://someimage

问题 I've got the following classes public class MyClass { private List<MyOtherClass> others; } public class MyOtherClass { private String name; } And I have JSON that may look like this { others: { name: "val" } } or this { others: [ { name: "val" }, { name: "val" } ] } I'd like to be able to use the same MyClass for both of these JSON formats. Is there a way to do this with Gson? 回答1: I came up with an answer. private static class MyOtherClassTypeAdapter implements JsonDeserializer<List

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . After searching through some existing libraries for JSON, I have finally ended up with these two: Jackson Google GSon I am a bit partial towards GSON, but word on the net is that GSon suffers from a certain celestial performance issue (as of Sept 2009). I am continuing my

问题 I have a trouble finding a way how to parse JSONArray. It looks like this: [{"name":"name1","url":"url1"},{"name":"name2","url":"url2"},...] I know how to parse it if the JSON was written differently (In other words, if I had json object returned instead of an array of objects). But it's all I have and have to go with it. *EDIT: It is a valid json. I made an iPhone app using this json, now I need to do it for Android and cannot figure it out. There are a lot of examples out there, but they
