代码实现

           //测试使用的csv下载地址
            String csvUrl = " http://sdxkyy.topwellsoft.com:8080/test.csv";
            //创建CSVFormat对象
            CSVFormat format = CSVFormat.RFC4180.withHeader().withDelimiter(',');
            //初始化CSVParser 对象
            CSVParser parse = CSVParser.parse(new URL(csvUrl), Charset.forName("GBK"), format);

            /*遍历解析的csv每一行数据，转换成实体*/
            for (CSVRecord record : parse) {
                log.info(record.toString());
            }

 finally {
            //关闭
            if (null != parse) {
                parse.close();
            }
        }
