var BASE_CONTEXT_PATH = $('meta[name=context-path]').attr("content");
BASE_CONTEXT_PATH = BASE_CONTEXT_PATH.substr(0, BASE_CONTEXT_PATH.length - 1);
<meta name="context-path" th:content="@{/}"/>
@{/}是Context相关的相对路径，在渲染时会自动添加上当前Web应用的Context名字，假设context名字为app，那么结果应该是/app/避免正式部署到服务器的路径问题。页面中直接使用如下：
<!-- Will produce 'http://localhost:8080/standard/type1' (plus rewriting) -->
<a th:href="@{/standard/{type}(type=${type})}">view</a>
<!-- Will produce '/gtvg/order/3/details' (plus rewriting) -->
<a href="details.html" th:href="@{/order/{orderId}/details(orderId=${o.id})}">view</a>
假设context名字为app，url如下：
<!-- Will produce 'http://localhost:8080/app/standard/type1' (plus rewriting) -->
<a th:href="@{/standard/{type}(type=${type})}">view</a>
<!-- Will produce '/app/gtvg/order/3/details' (plus rewriting) -->
<a href="details.html" th:href="@{/order/{orderId}/details(orderId=${o.id})}">view</a>
