spring mvc 如何绕过 *.html 文件的 DispatcherServlet? [英] spring mvc how to bypass DispatcherServlet for *.html files?

问题描述

web.xml 片段

<!-- Handles all requests into the application -->
<servlet>
    <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/app-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

它工作正常，但我不想让 Dispatcher Servlet 处理 *.html 请求.我该怎么做?谢谢.

It works fine but I'd like to NOT let the Dispatcher Servlet handle *.html requests. How do I I do that? Thanks.

推荐答案

将其映射到更具体的 url-pattern.

Map it on a more specific url-pattern.

<servlet-mapping>
    <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
    <url-pattern>/spring/*</url-pattern>
</servlet-mapping>

创建一个映射在/*上的Filter.

<filter-mapping>
    <filter-name>Your Dispatcher Filter</filter-name>
    <url-pattern>/*</url-pattern>
<filter-mapping>

在 doFilter() 方法中执行以下操作.

Which does the following in doFilter() method.

String uri = ((HttpServletRequest) request).getRequestURI();
if (uri.endsWith(".html")) {
    chain.doFilter(request, response); // Just let it go (assuming that files are in real not placed in a /spring folder!)
} else {
    request.getRequestDispatcher("/spring" + uri).forward(request, response); // Pass to Spring dispatcher servlet.
}
