java - Gson string with key -

I am using GSO to convert an object to Jason string, and its work is fine but when I I'm sending Jason to the webservice method using the post service, I have to add the parameter name of the post method in the string.

Example:

jsonString I'm getting new GSN from GSON ToJson (requestDataDTO) :

  {"Req1": {"AppId": "" 33 "," UserId ":" 1 "," UserToken ":" 4 "} , "Req1": {"AppId": "-33" "3", "UserId": "1", "UserToken": "4"}}  

jsonString I want to: "" "", "User ID": "1", "usercut": "4"}, "rake 1": {"request": {"request": {"blank": {"APID": "2", "third party": {3} "APIID": "-33", "thirdparty": "3", "user-id": "1", "usercuton": "4"}} }

For now I am joining GSN by adding this "requestDataDTO" string at the beginning of the GSN string.

What to gain Is there a way?

Assume that you have an object in some way:

  package com.dominikangerer.q25077756; Import com.google.gson.annotations.SerializedName; Public Class RequestDataDTO {// {"AppId": "2", "Third Party": "3", "Users ID ":" 1 "," UserToken ":" 4 "} @ Serialized Names (" APPID ") Private string app ID; @ SerializedName ("third party") private string third party; @ SerializedName ("UserId") private string userId; @ SerializedName ("UserToken") private string userToken; Public string getAppId () {return appId; } Public Zero setAppId (String API) {this.appId = appId; } Public string getThirdParty () {return third party; } Public Zero SetredParty (string third party) {this.thirdParty = thirdparty; } Public string getUserId () {return userId; } Public Zero SetUserID (String UserID) {this.userId = userId; } Public string getUserToken () {userToken; } Public Zero SetUseToken (String UserTouch) {this.userToken = userToken; The easiest and most readable solution for me is to create a cover / container class in which the Hashmap (key / value) is like this:  
  package com.dominikangerer.q25077756; Import java.util.HashMap; Public class requests data loss protocol String, request.datio & gt; RequestDataDTO = new hashmap & lt; String, request.datio & gt; (); Public Hashmap & lt; String, request.datio & gt; GetRequestDataDTO () {Refund Request DataDTO; } Public Zero SetRequestedTatio (Hashmap & lt; String, RequestDateTo & request; RequestDATTOO) {this.requestDataDTO = requestDataDTO; } Public Zero putRequestDataDTO (string key, RequestDataDTO value) {this.requestDataDTO.put (key, value); }}  
 
 To test it, just test it with a key like this: 
 
  // Enable Enable Printing Gson gson = new Gsonbuilder (). SetPrettyPrinting) .making (); // The very sluggish string to fill the objects by hand is Recijean = "{\" AppId \ ": \" 2 \ ", \" third party \ ": \" 3 \ ", \" UserId \ ": \" 1 \ ", \" UserToken \ ": \" 4 \ "}"; String rake 1 jason = "{\" AppId \ ": \" - 33 \ ", \" third party \ ": \" 3 \ ", \" UserId \ ": \" 1 \ ", \" UserToken \ " : \ "4 \"} "; Deserialize it with // GSN Request DataDTO REQ = gson.fromJson (reqJson, RequestDataDTO.class); RequestDataDTO req1 = gson.from Jason (req1Json, RequestDataDTO.class); // Container requestDataDataCountainEye container = new requestDataDataCentre (); // Add 2 Ruck Objects with some major containers. InputquestattiTTO ("rake", rake); Container.putquestionateto ("rake 1", rake 1); // Print it as a beautiful json system.out.println (gson.toJson (container));  
 
 You now have more flexibility if you want to add more meta information such as whole meta object or similar jason without adding hardcode string.
