ueditor 自定义上传图片，上传图片自定义

越来越不想写博客了，真的是累！

好了，废话不多说，进入正题。

前台：

既然你们都走到这里来了，那么前面的就不在多说了，直接进去配置好的页面。

需要上传的路径返回过去，记得把config.json 中的 imageUrlPrefix 清空。

后台：

            PrintWriter out = response.getWriter();

    }

    public void setUpfile(File[] upfile) {
        this.upfile = upfile;
    }

    public String[] getUpfileFileName() {
        return upfileFileName;
    }

    public void setUpfileFileName(String[] upfileFileName) {
        this.upfileFileName = upfileFileName;
    }

    public String[] getUpfileContentType() {
        return upfileContentType;
    }

    public void setUpfileContentType(String[] upfileContentType) {
        this.upfileContentType = upfileContentType;
    }

}

非常简单，核心是：只要知道哪里改上传的URL 和怎么返回数据格式。
