How to prevent Gson from converting a long number (a json string ) to scientific notation format?

Question

I need to convert json string to java object and display it as a long. The json string is a fixed array of long numbers:

{numbers
[ 268627104, 485677888, 506         


        

Answer 1

We can use the below code solution for number Long:

Document doc = documentCursor.next();  

JsonWriterSettings relaxed = JsonWriterSettings.builder().outputMode(JsonMode.RELAXED).build();  

CustomeObject obj = gson.fromJson(doc.toJson(relaxed), CustomeObject.class);
