${pageContext.request.contextPath}is an EL expression equivalent to the JSP expression <%= request.getContextPath() %>.
${pageContext.request.contextPath}是等效于 JSP 表达式的 EL 表达式<%= request.getContextPath() %>。
It is recommended to use ${pageContext.request.contextPath}instead of hard-coding your context path.
建议使用${pageContext.request.contextPath}而不是硬编码您的上下文路径。
E.g. <a href="${pageContext.request.contextPath}/info/page.html">Link</a>is better than <a href="http://abc.xyz.com/info/page.html">Link</a>
例如<a href="${pageContext.request.contextPath}/info/page.html">Link</a>比<a href="http://abc.xyz.com/info/page.html">Link</a>
