xml配置
<!-- 文件管理 --> <action name="fileManage" class="fileManageAction"/> <!-- 文件上传 --> <action name="fileUpload" class="fileUploadAction" />
JSP文件调用：
KindEditor.ready(function(K) { editor = K.create('#kindeditor', { uploadJson : '/manage/fileUpload.do', fileManagerJson : '/manage/fileManage.do', allowFileManager : true });
<s:textarea id="kindeditor" theme="simple" name="entity.description" cssStyle="width:700px;height:300px"/>
