请求json数据转成JSONArray，通过CDL.toString(jsonArray);转成string类型的数据，数据如下：
year,subject,subjectType,isPassVerifty,vcode,isOpenEnrollquery,isOpenTickeprint,adjname,genre,isPhotoVerifty,company,id,levelname,cityname,mobile,operateType,photo,thirdcompany,subjectid,adjcode,month,secondcompany,idcard,name,isOpenVerifty

最后将数据导出
//方法三：输出数据到文件中并将文件添加到zip压缩包中
byte[] bytes = csv.getBytes();
// 编码类型
response.setCharacterEncoding("utf-8");
// 请求头
response.setContentType("text/html; charset=utf-8");
InputStream fis = null;
ZipOutputStream zipOut = null;
try {
fis = new ByteArrayInputStream(bytes);
zipOut = new ZipOutputStream(response.getOutputStream());
FileUtils.zipFile(fis, zipOut, "ab.csv");
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
fis.close();
zipOut.close();
} catch (IOException e) {
e.printStackTrace();
}
}

} else {

//使用jackson转换
