How do I specify to use bigdecimal to handle numbers in gson? Below is the sample code and sample json string that I am trying to convert to a map.

`Type type = new TypeToken<Map<String, Object>>() { }.getType();
  Map<String, Object> data = new Gson().fromJson(strInput, type);`

Sample Json string :

[{
"Type":"Test",
"Amount":100231212111.00,
}]

The result I am getting is a map with double value for Amount. Please help to resolve this issue
