Bootstrap FileInput实现图片上传功能

本文实例为大家分享了Bootstrap FileInput实现图片上传功能的具体代码，供大家参考，具体内容如下

html代码：

 图片
 
   uploadData(HttpServletRequest request, HttpServletResponse response) throws Exception{
  request.setCharacterEncoding("UTF-8");
  Map json = new HashMap();
  MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
 
  
  MultipartFile multipartFile = null;
  Map map =multipartRequest.getFileMap();
  for (Iterator i = map.keySet().iterator(); i.hasNext();) {
   Object obj = i.next();
   multipartFile=(MultipartFile) map.get(obj);
 
  }
  
  String filename = multipartFile.getOriginalFilename();
 
  InputStream inputStream;
  String path = "";
  String fileMd5 = "";
  try {
   
   inputStream = multipartFile.getInputStream();
   File tmpFile = File.createTempFile(filename,
   filename.substring(filename.lastIndexOf(".")));
   fileMd5 = Files.hash(tmpFile, Hashing.md5()).toString();
   FileUtils.copyInputStreamToFile(inputStream, tmpFile);
   
   path = minioFileUtil.uploadCustomize(multipartFile.getInputStream(), filename.substring(filename.lastIndexOf(".")), "",multipartFile.getContentType());
   
//   path = AliOSSUtils.getInstance().multpartFileUpload(multipartFile,"bike");
   tmpFile.delete();
 
  } catch (Exception e) {
   e.printStackTrace();
   logger.error("上传失败",e);
   json.put("fileMd5", fileMd5);
   json.put("message", "上传失败");
   json.put("status", false);
   json.put("filePath", path);
   return json;
  }
  json.put("fileMd5", fileMd5);
  json.put("message", "上传成功");
  json.put("status", true);
  json.put("filePath", path);
  json.put("key", UUIDGenerator.getUUID());
  return json;
 }

@RequestMapping("/edit/deleteData/{id}")
@ResponseBody
@Transactional(rollbackFor = Exception.class)
public AjaxResult deleteData(@PathVariable("id")String id, HttpServletRequest request) throws Exception{
 String key = request.getParameter("key");
 Record record = recordService.getById(id);
 String picUrls = record.getPicUrls();
 String deleteName = "/" + key;
 if (picUrls.indexOf("^_^" + deleteName) > -1) {
  picUrls = "^_^" + picUrls.replace(deleteName, "");
 }
 if (picUrls.indexOf(deleteName + "^_^") > -1) {
  picUrls = picUrls.replace(deleteName + "^_^", "");
 }
 if (picUrls.indexOf(deleteName) > -1) {
  picUrls = picUrls.replace(deleteName, "");
 }
 record.setPicUrls(picUrls);
 if (recordMapper.updatePicsById(record) == 1) { 
  minioUtil.removeObject(bucketName, key);
  return success(key);
 }
 return error();
}

修改 fileInput 源码：

self._handler($el, 'click', function () {
  if (!self._validateMinCount()) {
   return false;
  }
  self.ajaxAborted = false;
  self._raise('filebeforedelete', [vKey, extraData]);
  //noinspection JSUnresolvedVariable,JSHint
  $.modal.confirm("确定删除原文件？删除后不可恢复",function () { //初始化回显的图片在删除时弹出提示框确认。
  if (self.ajaxAborted instanceof Promise) {
   self.ajaxAborted.then(function (result) {
    if (!result) {
     $.ajax(settings);
    }
   });
  } else {
   if (!self.ajaxAborted) {
    $.ajax(settings);
   }
  }
  })
 });
});
