Forming custom JSON Object from the JSON response from elastic search

Question

Am getting response from ElasticSearch, from that response i want to form another JSON with limited fields (like custom JSONObject).

Please find the response that am getting from elastic search.

{ "took":93, "timed_out":false, "_shards":{ "total":5, "successful":5, "skipped":0, "failed":0 }, "hits":{ "total":1, "max_score":1.0, "hits":[ { "_index":"attachment", "_type":"doc", "_id":"87740", "_score":1.0, "_source":{ "app_language":"ES", "filetype":"PB", "attachment":{ "date":"2006-05-03T15:17:53Z", "content_type":"application/pdf", "author":"JJamesN", "language":"en", "title":"Microsoft Word - te7000pb.doc", "content":"European Electronic Controls Catalog ", "content_length":12267 }, "ext":"pdf", "fileContent":"JVBERi0xLjQNJeLjz9MNCjQ3ID" } } ] } }

Please find my java code that am trying to manipulate the response JSON to create a separate JSON with limited fields.

JSONObject jsonObject = new JSONObject(responseBody); JSONObject hits = jsonObject.getJSONObject("hits"); JSONArray hitsArray=hits.getJSONArray("hits"); System.out.println("Hits---->"+hitsArray.toString());

From the response JSON, i just want to create a new JSON with the following Structure and fields.

 { "app_language":"ES", "filetype":"PB", "attachment.content" : "European Electronic Controls Catalog ", "ext":"pdf", }

Try this:

JSONObject jsonBody = new JSONObject(); jsonBody.put("app_language","value"); jsonBody.put("filetype","value"); jsonBody.put("attachment.content","value"); jsonBody.put("ext",ext); //String requestBody = jsonBody.toString();

Just extract your values from response and use it any where you want. Hope this helps.
