引用ckeditor

<script type="text/javascript" src="static/ckeditor/ckeditor.js"></script>

<textarea name="cktest"></textarea>
<script type="text/javascript">
    CKEDITOR.replace("cktest");
</script>

删除imag.js中的文本

将image.js中的hidden属性值改为0(总之为false 就ok 了)

修改config.js属性

CKEDITOR.editorConfig = function(config) {
    // Define changes to default configuration here. For example:
    // config.language = 'fr';
    // config.uiColor = '#AADC6E';
    config.image_previewText = '';
    config.removeDialogTabs = 'image:advanced;image:Link';//隐藏超链接与高级选项
    config.filebrowserImageUploadUrl = "http://localhost:8888/moon-web/hello/upload";//上传图片的地址
};

编写上传的代码（切记：不要用spring的上传方式{用spring的配置方式会出现各种各样的问题}）

@RequestMapping(value="/upload")
public void fileUpload(HttpServletRequest request, HttpServletResponse response) {
    String DirectoryName = "uploads";
    try {
        ImageUploadUtil.ckeditor(request, response, DirectoryName);
    } catch (IllegalStateException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
