* Ant风格的路径匹配器。<br>
* 来自Spring-core和Ant
*
* <p>匹配URL的规则如下：<br>
* <ul>
* <li>{@code ?} 匹配单个字符</li>
* <li>{@code *} 匹配0个或多个字符</li>
* <li>{@code **} 0个或多个路径中的<em>目录节点</em></li>
* <li>{@code {hutool:[a-z]+}} 匹配以"hutool"命名的正则 {@code [a-z]+}</li>
* </ul>
*
* <p>例子: </p>
* <ul>
* <li>{@code com/t?st.jsp} &mdash; 匹配 {@code com/test.jsp} 或 {@code com/tast.jsp} 或 {@code com/txst.jsp}</li>
* <li>{@code com/*.jsp} &mdash; 匹配{@code com}目录下全部 {@code .jsp}文件</li>
* <li>{@code com/&#42;&#42;/test.jsp} &mdash; 匹配{@code com}目录下全部 {@code test.jsp}文件</li>
* <li>{@code cn/hutool/&#42;&#42;/*.jsp} &mdash; 匹配{@code cn/hutool}路径下全部{@code .jsp} 文件</li>
* <li>{@code org/&#42;&#42;/servlet/bla.jsp} &mdash; 匹配{@code cn/hutool/servlet/bla.jsp} 或{@code cn/hutool/testing/servlet/bla.jsp} 或 {@code org/servlet/bla.jsp}</li>
* <li>{@code com/{filename:\\w+}.jsp} 匹配 {@code com/test.jsp} 并将 {@code test} 关联到 {@code filename} 变量</li>
* </ul>
*
* <p><strong>注意:</strong> 表达式和路径必须都为绝对路径或都为相对路径。
