/ 11 января 2019

Ссылка на quick start для OpenCSV, возникла проблема с открытием файла, который отображается как присутствующий в ОС, и с использованием exists для демонстрации.

Код: 

package net.bounceme.dur.basexfromjaxb.csv;

import com.opencsv.CSVReaderHeaderAware;
import java.io.File;
import java.io.FileReader;
import java.net.URI;
import java.util.Map;
import java.util.logging.Logger;

public class ReaderForCVS {

    private static final Logger LOG = Logger.getLogger(ReaderForCVS.class.getName());

    public ReaderForCVS() {
    }

    public void unmarshal(URI inputURI) throws Exception {
        LOG.info(inputURI.toString());

        File encyptFile = new File(inputURI);
        System.out.println(encyptFile.exists());

        Map<String, String> values = new CSVReaderHeaderAware(new FileReader("file:/home/thufir/jaxb/input.csv")).readMap();
    }
}

файл не найден:

Почему это работает, я не знаю: 

public void unmarshal(URI inputURI) throws Exception {
    FileReader f = new FileReader(new File(inputURI));
    Map<String, String> values = new CSVReaderHeaderAware(f).readMap();
}
...
