Using FasterXML's CSV package: https://github.com/FasterXML/jackson-dataformats-text/tree/master/csv

public static List> read(File file) throws JsonProcessingException, IOException {
    List> response = new LinkedList>();
    CsvMapper mapper = new CsvMapper();
    CsvSchema schema = CsvSchema.emptySchema().withHeader();
    MappingIterator> iterator = mapper.reader(Map.class)
            .with(schema)
            .readValues(file);
    while (iterator.hasNext()) {
        response.add(iterator.next());
    }
    return response;
}
