百度富文本编辑器 UEditor 1.4.3 自定义图片保存路径

百度UEditor图片文件改变默认保存到项目根路径，自定义上传路径或远程服务器：http://blog.csdn.net/slyn_2004/article/details/53868547

1. js实例化编辑器：

//实例化编辑器 
    var ue = UE.getEditor('notice-content');
    UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
    UE.Editor.prototype.getActionUrl = function(action) {
        if (action == 'uploadimage' || action == 'uploadscrawl' || action == 'listimage') {
            return '/myproject/ueditorUpload';
        } else {
            return this._bkGetActionUrl.call(this, action);
        }
    }

2. 后台（用的是Spring MVC）：

    @RequestMapping(value = "/ueditorUpload")  
    public void uploadUEditorImage(@RequestParam(value = "upfile", required = false) MultipartFile file,
    HttpServletResponse response, HttpServletRequest request) throws Exception {
            request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
JSONObject json=new JSONObject();
PrintWriter out = response.getWriter();

try {
String root = "E:\\tmp";
            String fileName = file.getOriginalFilename();
            String fileSuffix = fileName.substring(fileName.indexOf(".")+1);

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
            String directory = "\\file\\image\\" + dateFormat.format(new Date()) + "\\";
            //Util.getRandomString(int length)：返回由length个任意字母组成的字符串
            String path =directory + Util.getRandomString(12) + "." + fileSuffix;
            new File(root + directory).mkdir();
file.transferTo(new File(root + path));

json.put("state", "SUCCESS");
json.put("title", file.getName());
json.put("url", path);//图片访问路径
json.put("original", file.getName());
} catch (Exception e) {
json.put("state", "上传图片出错");
}
out.print(json.toString());
    }

3. config.json中：

    "imageUrlPrefix": "http://localhost:8080",
    "imagePathFormat": "/myproject/file/image/{yyyy}{mm}{dd}/{time}{rand:6}",

4. 修改tomcat虚拟路径： http://blog.csdn.net/eunyeon/article/details/71124314
