ajax springMvc 异步 上传 文件
很久没有写文件上传的代码了,以下代码支持异步上传,备注一下。
1.页面设置
<div> <input type="file" class="easyui-linkbutton" id="excelFile" name="excelFile" size="20" maxlength="20"/> <input type="button" class="easyui-linkbutton" onClick="uploadFile();" style="width:80px" value="上传" /> </div>
2. js 代码
function uploadFile() { var url = "upload.htm?method=upload')"; var formData = new FormData(); formData.append('excelFile', $('#excelFile')[0].files[0]); jQuery.ajax({ url: url, type: 'POST', cache: false, data: formData, processData: false, contentType: false }).done(function(res) { console.log(res); }).fail(function(res) { console.log("failed="+res); }); } </
3. Action code
@RequestMapping(value="/upload.htm", params = "method=upload") public String upload(@RequestParam("excelFile") MultipartFile file, ModelMap model,HttpServletResponse response) { String fileName = file.getOriginalFilename(); InputStream is = file.getInputStream(); }
