如何在运行时在web.xml中配置安全域下的url-pattern？

Question

我在web.xml中将安全域配置为：

<security-constraint>
    <display-name>all</display-name>
        <web-resource-collection>
            <web-resource-name>all</web-resource-name>
            <url-pattern>${param-name</url-pattern>
            <http-method>POST</http-method>
            <http-method>GET</http-method>
            <http-method>PUT</http-method>
            <http-method>DELETE</http-method>
            <http-method>PATCH</http-method>
        </web-resource-collection>
        <auth-constraint>
        <role-name>admin</role-name>
    </auth-constraint>
</security-constraint>

现在我想在服务器启动时通过java在运行时设置url-pattern。我该怎么做呢？
