CSV Reader

Read CSV file using Jackson CsvMapper , using bytes[] 

byte[] bytes = getBytes(); 

CsvSchema billingLineSchema = csvFileSchemaBuilder.getSchema().withHeader();

CsvMapper csvMapper = new CsvMapper(); 

ObjectReader objectReader =
        csvMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)
                .readerFor(BillingLine.class)
                .with(billingLineSchema);
 

MappingIterator<BillingLine> iterator;
try {
    iterator = objectReader.readValues(bytes);
} catch (Exception e) {
    throw new IllegalStateException("could not read");
}
 

List<BillingLine> results = new ArrayList<>();
iterator.forEachRemaining(results::add);
System.out.println(results.get(0).toString());

 

Read CSV file using Jackson CsvMapper , using Reader

Reader reader = new FileReader("./converted"-01.json");

CsvSchema billingLineSchema = csvFileSchemaBuilder.getSchema().withHeader();

 ObjectReader objectReader =
            csvMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)
                    .readerFor(BillingLine.class)
                    .with(billingLineSchema);

 MappingIterator<BillingLine> iterator;
    try {
        iterator = objectReader.readValues(reader);
    } catch (IOException e) {
        throw new IllegalStateException("could not access file");
    }
    List<BillingLine> results = new ArrayList<>();
    iterator.forEachRemaining(results::add);
    System.out.println(results.get(0).toString());
