How to parse with GSON when identifier has space in name

Question

How to parse with GSON when file looks like this

{
    \"Person Id\":\"test\",
    \"Last Name\": \"test\",
    \"First Name\":\"test\"
}

Answer 1

I have tried to parse this JSON but I didn't use GSON to parse this. I'll share my code with you, kindly consider only as a supplementary solution to solve the issue:

String parse = "{\"Person Id\":\"test\",\"Last Name\": \"lname\",\"First Name\":\"fname\"}";
try {
    JSONObject jsonObject   =   new JSONObject(parse);
    String id = jsonObject.getString("Person Id");
    System.out.println("id="+id);
    System.out.println("lname="+jsonObject.getString("Last Name"));
    System.out.println("fname="+jsonObject.getString("First Name"));
} catch (JSONException e) {
    e.printStackTrace();
}

While still using GSON you can do this by adding an annotation. For instance:

class Person{
    @SerializedName("Person Id") public String PersonId;
    @SerializedName("Last Name") public String LastName;
    @SerializedName("First Name") public String FirstName;
}

You can find more details in the GSON documentation: https://sites.google.com/site/gson/gson-user-guide#TOC-JSON-Field-Naming-Support
