opencsv一个简单的CSV解析Java包。它封装了CSV格式文件的输出和读入，可以自动处理CSV格式中的特殊字符。

示例

File tempFile = new File("./Group" + querytime + ".csv");

           OutputStreamWriter osw = null;

            try {

                osw = new OutputStreamWriter( new FileOutputStream(tempFile),"GB18030" );

           } catch (Exception e1) {

                e1.printStackTrace();

           }

            try {

                CSVWriter writer = new CSVWriter(osw);

                 for ( int i = 0; i < data. length; i++) {

                     writer.writeNext(data[i]);

                }

                writer.close();

           } catch (Exception e) {

                 logger.info( "getgroupCSV", e.getLocalizedMessage());

           }
