thymeleaf 获取项目路径 contextPath

thymeleaf 标签：

${#httpServletRequest.getContextPath()}

直接引用 th:οnclick="@{'location.href=\'' + ${#httpServletRequest.getContextPath()} + '/xxxx\'}"

其它：${#servletContext.contextPath} 

javascript中引用

<!-- 根路径 -->
<script type="text/javascript" th:inline="javascript">
   /*<![CDATA[*/
   ctxPath = /*[[@{/}]]*/ '';
   /*]]>*/

console.info(ctxPath);
</script>
