gson

问题 I am using the Gson function toJson for the = , > and < operators, and in the final string they are interpreted as \u003e . Is there a special feature I need to add or take care of? 回答1: You should disable HTML escaping , here is a sample that illustrates it: Gson gson1 = new Gson(); String s1 = gson1.toJson("<>"); Gson gson2 = new GsonBuilder().disableHtmlEscaping().create(); String s2 = gson2.toJson("<>"); s1: "\u003c\u003e" s2: "<>" 来源： https://stackoverflow.com/questions/17092044/gson

问题 We are currently using Java EE 5 and we do something like the following for turning POJO into JSON before sending the response. @GET @Path("/books") @Produces(MediaType.APPLICATION_JSON) public Response getBooks() { List<Book> listOfBooks = getMiscService().getbooks(); String response = "{\"books\":" + gson.toJson(listOfBooks) + "}"; return Response.status(Response.Status.OK).entity(response).build(); } we are using gson API of google. Now that we are restructuring the code to Java EE 7 API

问题 I’m trying to use a OpenFeign client to hit an API, get some JSON, and convert it to a POJO array. Previously I was simply getting a string of JSON and using Gson to convert it to the array like so FeignInterface { String get(Request req); } String json = feignClient.get(request); POJO[] pojoArray = new Gson().fromJson(json, POJO[].class); This was working. I would like to eliminate the extra step and have feign auto decode the JSON and return a POJO directly though, so I am trying this

问题 I'm trying to extract some data from a JsonObject. The problem is that the fields that come inside that json have unpredictable names.

问题 I am using Axis to call a SOAP-based web service. I'm then trying to serialize the returned remote object as JSON, using the Google Gson library. The serialization to JSON fails, with Gson complaining that "there are multiple elements with the name __equalsCalc()). When I inspect the returned object in my IDE (Eclipse), I can see that this is true -- the returned object has three members called __equalsCalc() and another three called __hashCode. I know from looking around that these are added

问题 I am new to stackoverflow. I am creating an Java application which it will get data from a web server. The data is in json format.

问题 I've created a set of classes (pojos) that need to be transformed into json. because i have a constraint that json field names adhere to a certain format, i've settled on gson as my library of choice, as it allows for annotations of field names. so, i have json field names like asset_type , preview_image_thumbnail , etc. along with that, any metadata fields must have the format, metadata:<metadata-field-name> . so, what this comes down to is that my metadata:tags and metadata:site annotations

问题 I am using Gson 1.6 and Spring Framework 3.0 for a Java web app on WebSphere 6.1. I have some Spring beans for which the actual instance is a CGLIB proxy. When I attempt to serialize these beans via Gson, the non-primitive properties of the class are not serialized. Instead I get something like: { "CGLIB$BOUND":true, "CGLIB$CONSTRUCTED":true, "booleanProperty":true, "anotherBooleanProperty":true, } where I was expecting something more like { "stringProperty":"stringValue"
