上传文件

两种方式，一种是直接对上传的文件的流进行处理，然后直接存库；一种是将文件上传到一个远程服务器，然后将文件在远程服务器的地址返回。
1：代码
String filename=requestVo.getFilename();
String url=requestVo.getUrl();
URL urlParam = new URL(url);
// 打开链接
HttpURLConnection conn = (HttpURLConnection) urlParam.openConnection();

// 超时响应时间为5秒
conn.setConnectTimeout(5 * 1000);

2：直接上传文件 那么就是直接从文件流中获取数据，直接进行处理
String filename=requestVo.getFilename();
String url=requestVo.getUrl();
URL urlParam = new URL(url);
// 打开链接
HttpURLConnection conn = (HttpURLConnection) urlParam.openConnection();
// 设置请求方式为”GET”
conn.setRequestMethod(“GET”);
// 超时响应时间为5秒
conn.setConnectTimeout(5 * 1000);
// 加载excel
List list = new ArrayList();// 订单
String excelDatas = ParseExcelUtil.getInstance().loadExcel(filename, conn.getInputStream(),
list);
System.out.println(url);
request.setCharacterEncoding(“UTF-8”);
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
MultipartFile file = multipartRequest.getFile(“uploadFile”);
InputStream inputStream = file.getInputStream();
String s = file.getOriginalFilename();
