关于使用OpenCsv导入大数据量报错的问题

CSVParser csvParser = new CSVParserBuilder().build();
try (CSVReader readerCsv = new CSVReaderBuilder(new InputStreamReader(csv)).withCSVParser(csvParser).build()) {
    String[] lines;
    while ((lines = readerCsv.readNext()) != null) {
        doRead(lines);
    }
} catch (CsvValidationException e) {
    throw new IOException(e);
}

RFC4180Parser rfc4180Parser = new RFC4180ParserBuilder().build();
try (CSVReader readerCsv = new CSVReaderBuilder(new InputStreamReader(csv)).withCSVParser(rfc4180Parser).build()) {
    String[] lines;
    while ((lines = readerCsv.readNext()) != null) {
        doRead(lines);
    }
} catch (CsvValidationException e) {
    throw new IOException(e);
