Answer 1

Recent versions of OpenCSV deprecate the method parse(X, Y) and it's recommenced to use BeanBuilder instead, so the top answer is out of date.

try {
    CsvToBeanBuilder beanBuilder = new CsvToBeanBuilder<>(new InputStreamReader(new FileInputStream("your.csv")));

    beanBuilder.withType(PersonCSV.class);
    // build methods returns a list of Beans
    beanBuilder.build().parse().forEach(e -> log.error(e.toString()));

} catch (FileNotFoundException e) {
    log.error(e.getMessage(), e);
}

This methods allows you to clean up the code and remove MappingStrategy (you can still use it if you like spaghetti), so you can annotate your CSV class as follows:

@CsvDate("dd/MM/yyyy hh:mm:ss")
@CsvBindByName(column = "Time Born", required = true)
private Date birthDate;
