kindeditor Springmvc 整和解决图片上传问题

1. 在编辑页面引入js

2.textarea绑定

3.初始化插件

 1 var editor = KindEditor.create('textarea[name="content"]', {
 2         uploadJson : basePath + '/kindeditor/fileUpload',  
 3         fileManagerJson : basePath + '/kindeditor/fileManager',  
 4         allowFileManager : true,
 5         items : ['source', '|', 'undo', 'redo', '|', 'preview', 'template', 'cut', 'copy', 'paste',
 6                  'plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright',
 7                  'justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript',
 8                  'superscript', 'clearhtml', 'quickformat', 'selectall', '|', 'fullscreen', '/',
 9                  'formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold',
10                  'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image','multiimage',
11                  'flash', 'media', 'insertfile', 'table', 'hr', 'emoticons', 'baidumap', 'pagebreak',
12                  'anchor', 'link', 'unlink']
13     });
