ueditor 单图片上传后提示上传错误 本地已经上传到项目文件夹下 但无法展示

前端的js异步方法无法正常的执行下去，修改ueditor.all.js，大概在24568行

// domUtils.on(iframe, 'load', callback);// form.action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params);// form.submit();

换成下面代码

var formdata = new FormData(form);var xhr= new XMLHttpRequest();xhr.open("POST", me.getOpt('serverUrl')+'?action=uploadimage', true);xhr.onreadystatechange = function() {if (xhr.readyState === 4)if ((xhr.status >=200 && xhr.status < 300) || xhr.status == 304)alert(xhr.responseText);}xhr.send(formdata);xhr.onreadystatechange = function () {if(xhr.readyState == 4) {console.log(xhr.responseText);var json = JSON.parse(xhr.responseText);// alert(response.state);if (json.state == 'SUCCESS' && json.url) {loader = me.document.getElementById(loadingId);loader.setAttribute('src', json.url);loader.setAttribute('_src', json.url);loader.setAttribute('title', json.title || '');loader.setAttribute('alt', json.original || '');loader.removeAttribute('id');domUtils.removeClasses(loader, 'loadingclass');} else {showErrorLoader && showErrorLoader(json.state);}}}

另外再附上后端的上传图片的接口

@RequestMapping("/ueditor")@ResponseBodypublic Object test(HttpServletRequest request,@RequestParam(value = "action") String action,@RequestParam(value = "upfile", required = false) MultipartFile file) throws Exception {switch (action) {case "config": // 加载返回ueditor配置文件conf/config.jsonreturn ResourceUtils.getConfig();case "uploadimage": // 上传图片String state = "SUCCESS";String uploadHttpUrl = fileUpload(file);return resultMap(file, state, uploadHttpUrl);case "uploadvideo": // 上传视频String state2 = "SUCCESS";String uploadHttpUrl2 = fileUpload(file);return resultMap(file, state2, uploadHttpUrl2);case "uploadfile": // 上传文件String state3 = "SUCCESS";String uploadHttpUrl3 = fileUpload(file);return resultMap(file, state3, uploadHttpUrl3);default:return "无效action";}}private Map<String, Object> resultMap(MultipartFile file, String state, String uploadHttpUrl) {Map<String, Object> resMap = new HashMap<String, Object>();resMap.put("state", state); //"SUCCESS" 表示成功resMap.put("title", file.getOriginalFilename());resMap.put("original", file.getOriginalFilename());resMap.put("type", file.getContentType());resMap.put("size", file.getSize());resMap.put("url", uploadHttpUrl);return resMap;}
