        try {
            File f = new File(filePath);
            FileOutputStream fos = new FileOutputStream(f,true);
            OutputStreamWriter writer = new OutputStreamWriter(fos,"utf-8");
//            BufferedWriter writer = new BufferedWriter(new FileWriter(f,true));
            // 创建CSV写对象
            CsvWriter csvWriter = new CsvWriter(writer,',');
            //CsvWriter csvWriter = new CsvWriter(filePath);
            // 写表头
            String[] header = {"编号","姓名","年龄"};
            String[] content = {"55378901","王五","75"};
            String[] content1 = {"55378909","张三","25"};
            csvWriter.writeRecord(header);
            csvWriter.writeRecord(content);
            csvWriter.writeRecord(content1);
            csvWriter.flush();
            csvWriter.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
