spring集成百度编辑器

近期接到工作任务，在线hmtl5技术预演，将文字或图片生成html文件作为培训课件供app用户参与考试，想到了百度编辑器，于是乎就引入了百度编辑器功能。

先说下依赖文件：

js模块

<link rel="stylesheet" href="/plugins/ueditor/themes/default/css/ueditor.css" ><script type="text/javascript" src="/plugins/slimScroll/jquery.slimscroll.min.js"></script><script type="text/javascript" src="/plugins/ueditor/ueditor.config.js"></script><script type="text/javascript" src="/plugins/ueditor/ueditor.all.js"></script>

资源文件:

{    "imageActionName": "uploadimage",    "imageFieldName": "upfile",     "imageMaxSize": 2048000,     "imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp",".PNG"],    "imageCompressEnable": true,     "imageCompressBorder": 1600,    "imageInsertAlign": "none",     "imageUrlPrefix": "",    "imagePathFormat": "{yyyy}{mm}{dd}_{time}_{rand:6}" ,        "catcherLocalDomain": ["127.0.0.1", "localhost", "img.baidu.com"],    "catcherActionName": "catchimage",     "catcherFieldName": "source",     "catcherPathFormat": "{yyyy}{mm}{dd}_{time}_{rand:6}",     "catcherUrlPrefix": "",    "catcherMaxSize": 2048000,     "catcherAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp",".PNG"]}
