Convert Json - Integers without quotes, Strings with quotes - json

Question

I'm reading a CSV file with some strings and some integer columns and converting them to JSON. While this conversion, all fields and values seem to have double quotes around them. However I want the integer values NOT to have double quotes.
I'm using Jackson Fasterxml and here's my code snippet
File input = new File("/Users/name/1.csv");
File output = new File("/Users/name/output.json");
CsvSchema csvSchema = CsvSchema.builder().setUseHeader(true).build();
CsvMapper csvMapper = new CsvMapper();
// Read data from CSV file
List<Object> readAll = csvMapper.readerFor(Map.class).with(csvSchema).readValues(input).readAll();
ObjectMapper mapper = new ObjectMapper();
mapper.configure(JsonGenerator.Feature.QUOTE_NON_NUMERIC_NUMBERS, true);
// Write JSON formated data to output.json file
mapper.writerWithDefaultPrettyPrinter().writeValue(output, readAll);
Here's my expected output: Output, please note id and budget do not have double quotes on them
[ {
"id" : 120,
"name" : "Name 1",
"type" : "type1",
"budget" : 100
},
{
"id" : 130,
"name" : "Name 2",
"type" : "type2",
"budget" : 200
},
{
"id" : 140,
"name" : "Name 3",
"type" : "type2",
"budget" : 130
},
{
"id" : 150,
"name" : "Name 4",
"type" : "type4",
"budget" : 400
}
}]
However all fields and values have quotes after conversion
[ {
"id" : "120",
"name" : "Name 1",
"type" : "type1",
"budget" : "100"
},
{
"id" : "130",
"name" : "Name 2",
"type" : "type2",
"budget" : "200"
},
{
"id" : "140",
"name" : "Name 3",
"type" : "type2",
"budget" : "130"
},
{
"id" : "150",
"name" : "Name 4",
"type" : "type4",
"budget" : "400"
}
}]

Unfortunately right now it is not possible to read CSV and specify type for using schema only. You can create POJO with private int budget; and conversion will be done automatically. For other solutions take a look on this question: jackson-dataformat-csv: Mapping number value without POJO where you can see:
