csv测试类。用起来，就是那么简单。每个单元格都是以逗号分隔

        System.out.println(dataList);

//        boolean isSuccess=CSVUtils.exportCsv(new File("E:/export/ljq"+DateUtil.getCurrentDateStr(DateUtil.DATETIMEFMTSSSS)+".csv"), dataList);
        System.out.println(isSuccess);
    }

    /**

//    @Test
    public void importCsv()  {
        List<String> dataList=CSVUtils.importCsv(new File("E:/test/ljq.csv"));
        if(dataList!=null && !dataList.isEmpty()){
            for(String data : dataList){
                System.out.println(data);
            }
        }
    }

}

结果：以逗号分隔，以\n换行，字符串加上\t，数字加上双引号""

"1004760934201504280095156624" ,"231,215.99"

"1004800934201504270092770541" ,"1.1"

"1002190934201504260091077987"

"AA,BB,CC","231,231,231,215.99"
