xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">

<link th:href="@{/plugin/jquery-easyui-1.5.2/themes/icon.css}" rel="stylesheet"/>
<link th:href="@{/plugin/jquery-easyui-1.5.2/themes/default/easyui.css}" rel="stylesheet"/>
<script th:src="@{/plugin/jquery/jquery-3.2.1.js}"></script>
</head>
