Java环境下使用CsvReader()读取CSV文件

  private List<CsvRow> getCsvFile(String filePath) {
        //新建一个CsvReadConfig配置对象
        CsvReadConfig csvReadConfig = new CsvReadConfig();
        //新建一个CsvReader对象
        CsvReader csvRows = new CsvReader(csvReadConfig);
        //初始化数据
        CsvData read = null;
            read = csvRows.read(new File(filePath), CharsetUtil.CHARSET_UTF_8);
        //读取数据
        List<CsvRow> rows = read.getRows();
        return rows;
    }
