This tutorial explains how to handle the encoding issue by using GSON. Below is a sample program in which GSON was converting string, with some special character, into some encoded character.
Map<String, String> dataMap = new HashMap<String, String>();
dataMap.put("userid", "sdswSSEdafsdy2y4==");
Gson gson = new Gson();
String json = gson.toJson(dataMap);
System.out.println("Json result - "+json);
But when we printed the GSON string it gave some different output other than what was supposed to be.
Json result - sdswSSEdafsdy2y4\u003d\u003d
The issue with the above code is GSON is encoding my string “=” sign to \u003d. To handle this we need to use disableHtmlEscaping() with GSON, like the way it is written below –
Solution:
Map<String, String> dataMap = new HashMap<String, String>();
dataMap.put("userid", "sdswSSEdafsdy2y4==");
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
String json = gson.toJson(dataMap);
System.out.println("Json result - "+json);
