OpenCSV – How to map selected columns to Java Bean regardless of order?

You can use HeaderColumnNameTranslateMappingStrategy. Lets assume your CSV has the following columns: Id, Fname, Telephone, Lname, Address for the sake of simplicity.

CsvToBean<Person> csvToBean = new CsvToBean<Person>();

Map<String, String> columnMapping = new HashMap<String, String>();
columnMapping.put("Id", "id");
columnMapping.put("Fname", "fname");
columnMapping.put("Lname", "lname");

HeaderColumnNameTranslateMappingStrategy<Person> strategy = new HeaderColumnNameTranslateMappingStrategy<Person>();
strategy.setType(Person.class);
strategy.setColumnMapping(columnMapping);

List<Person> list = null;
CSVReader reader = new CSVReader(new InputStreamReader(ClassLoader.getSystemResourceAsStream("test.csv")));
list = csvToBean.parse(strategy, reader);

The columnMapping will map the columns with your Person object.
