读取文件:有三个方法。自行取用

public static void csvReadOperation() throws IOException {
        File file = new File("F:\\Excel\\customer-info.csv");
        CsvReader csvReader = new CsvReader();
        csvReader.setContainsHeader(true);

        CsvContainer csv = csvReader.read(file, StandardCharsets.UTF_8);
        for (CsvRow row : csv.getRows()) {
            System.out.println("First column of line: " + row.getField("用户编号"));
        }
    }

    public static void csvReadOperation1() throws IOException {
        File file = new File("F:\\Excel\\customer-info.csv");
        CsvReader csvReader = new CsvReader();

        CsvContainer csv = csvReader.read(file, StandardCharsets.UTF_8);
        for (CsvRow row : csv.getRows()) {
            System.out.println("Read line: " + row);
            System.out.println("First column of line: " + row.getField(0));
            if (row.getOriginalLineNumber() != 1) {
                ResultInfo resultInfo = new ResultInfo();
                resultInfo.setUserId(row.getField(0));
                resultInfo.setUserPhone(row.getField(1));
                resultInfo.setUserName(row.getField(2));
                resultInfo.setRegistTime(row.getField(3));
                resultInfo.setUserlevel(row.getField(4));
                resultInfo.setAppName(row.getField(10));
                listResultInfo.add(resultInfo);
            }

        }
    }

    public static void csvReadOperation2() throws IOException {
        File file = new File("F:\\Excel\\customer-info.csv");
        CsvReader csvReader = new CsvReader();

        try (CsvParser csvParser = csvReader.parse(file, StandardCharsets.UTF_8)) {
            CsvRow row;
            while ((row = csvParser.nextRow()) != null) {
                System.out.println("Read line: " + row);
                System.out.println("First column of line: " + row.getField(0));
            }
        }
    }
