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"/>

已经过完整测试，排除了BUG
