springmvc 使用ajx上传文件 不设置form enctype
最近在做一个小项目 碰到这个问题 解决方案如下
1.js代码如下 获取当前form 转换为formdata ajax提交到后台
var form = $("#importForm");
var formData =http://www.mamicode.com/new FormData($scope._window.find("#importForm"));
$.ajax({
type:"POST",
data:formData,
processData:false,
contentType:false,
url:$scope.webpath.p0path+"/cps-p0-web/importpiccontroller/importPickticket",
success:function(data){
alert("上传成功");
},
exception:function(data,textStatus){
}
});
后台代码解析
@ResponseBody @RequestMapping(value = "/importPickticket") public ResponseModel importPickticket(HttpServletRequest request,HttpServletResponse response) throws BussinessException{ ResponseModel responseModel = new ResponseModel(); try{
//上传文件后保存文件 String filePath = FileUpload.fileUpload(request, response); responseModel.setSuccess(true); }catch (BussinessException e) { }catch (Exception e) {
}
return null; } return null; }
//FileUpload 代码
public class FileUpload { public static String fileUpload(HttpServletRequest request, HttpServletResponse response) { try { //文件服务器名称 StringBuffer rename = new StringBuffer(); // ServletContext servletContext = request.getSession().getServletContext(); //获取服务器保存路径 String pathUrl = servletContext.getRealPath(PropertyPlaceholder.getProperty("fileUploadPath").toString()); //解析器解析request的上下文 CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(servletContext); //先判断request中是否包涵multipart类型的数据 if (multipartResolver.isMultipart(request)) { // 再将request中的数据转化成multipart类型的数据 MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request; // 获取文件名 Iterator<String> iter = multiRequest.getFileNames(); while (iter.hasNext()) { MultipartFile file = multiRequest.getFile((String) iter.next()); if (file != null) { rename.append(new Random().nextInt(99999)).append("_").append(System.currentTimeMillis()).append(file.getOriginalFilename()); File localFile = new File(pathUrl + "/" + rename.toString()); // 写文件到本地 file.transferTo(localFile); } } } return pathUrl + "/" + rename.toString(); } catch (Exception e) { throw new BussinessException("FileUpload.fileUpload.BusinessException", e); } } }
