URL pattern are for servlet and filters. For servlet
URL 模式用于 servlet 和过滤器。对于 servlet
<servlet-mapping>
<servlet-name>Servlet-name</servlet-name>
<url-pattern>/< Pattern ></url-pattern>
</servlet-mapping>
For Filter
对于过滤器
<filter-mapping>
<filter-name>Filter-Name</filter-name>
<url-pattern>/< Pattern ></url-pattern>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>
Those are not for Html file. Infact there are no pattern configuration for JSPs too.
这些不适用于 Html 文件。事实上，JSP 也没有模式配置。

If you want to protect *.html files from direct access (by placing *.html files under WEB-INF) you can use a Servlet which would be only responsible for forwarding all such requests to intended html files.
如果您想保护 *.html 文件免于直接访问（通过将 *.html 文件放在 WEB-INF 下），您可以使用一个 Servlet，它只负责将所有此类请求转发到预期的 html 文件。
<servlet>
<servlet-name>HTMLServlet</servlet-name>
<servlet-class>my.package.HTMLServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HTMLServlet</servlet-name>
<url-pattern>/somepath/*.html</url-pattern>
</servlet-mapping>
Code in servlet class may look like this
servlet 类中的代码可能如下所示
...
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
String requestedPath = //... code for getting requested HTML path
request.getRequestDispatcher(requestedPath).forward(request, response);
}
...

If you don't mind to change your HTML page to JSP you can set url pattern for it like this:
如果您不介意将 HTML 页面更改为 JSP，您可以像这样设置 url 模式：
<servlet>
<servlet-name>Error</servlet-name>
<jsp-file>/pages/error.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>Error</servlet-name>
<url-pattern>/error</url-pattern>
</servlet-mapping>
