如何在web.xml中为Jetty配置静态资源的缓存？ [英] How to configure cache for static resources in web.xml for Jetty?

问题描述

我在读这篇文章：
http://docs.codehaus.org/ display / JETTY / LastModifiedCacheControl

它说

默认servlet允许通过使用cacheControl init参数
为静态内容设置缓存控制头
：

< pre class =lang-xml prettyprint-override> < init-param>
< param-name> cacheControl< / param-name>
< param-value> max-age = 3600，public< / param-value>
< / init-param>


但是，我不确定我使用默认的servlet。至少
这样的配置不在web.xml中：

  app> 
< display-name> Wicket QuickStart< / display-name> 
< context-param> 
< param-name> configuration< / param-name> 
< param-value> development< / param-value> 
< / context-param> 
< servlet> 
< servlet-name> quickstart< / servlet-name> 
< servlet-class> org.apache.wicket.protocol.http.WicketServlet< / servlet-class> 
< init-param> 
< param-name> applicationClassName< / param-name> 
< param-value> wicket.quickstart.WicketApplication< / param-value> 
< / init-param> 
< load-on-startup> 1< / load-on-startup> 
< / servlet> 
< servlet-mapping> 
< servlet-name> quickstart< / servlet-name> 
< url-pattern> / *< / url-pattern> 
< / servlet-mapping> 
< / web-app> 
  

我想为静态资源配置缓存，例如：

/ src / webapp / * ，即： / src / webapp / images，/ src / webapp / css，/ src / webapp / js 等。

我应该添加到 web.xml

解决方案

需要在web.xml中添加以下内容

 < servlet> 
< servlet-name> default< / servlet-name> 
< servlet-class> org.mortbay.jetty.servlet.DefaultServlet< / servlet-class> 
< init-param> 
< param-name> cacheControl< / param-name> 
< param-value> max-age = 3600，public< / param-value> 
< / init-param> 
< / servlet> 
  

I was reading this: http://docs.codehaus.org/display/JETTY/LastModifiedCacheControl

It says

The Jetty default servlet allows the cache control header to be set for static content by using the cacheControl init parameter using:

<init-param>
    <param-name>cacheControl</param-name>
    <param-value>max-age=3600,public</param-value>
</init-param>

However, I am not sure that I am using the default servlet. At least such configuration is not in web.xml:

<web-app>
    <display-name>Wicket QuickStart</display-name>
    <context-param>
        <param-name>configuration</param-name>
        <param-value>development</param-value>
    </context-param>
    <servlet>
        <servlet-name>quickstart</servlet-name>
        <servlet-class>org.apache.wicket.protocol.http.WicketServlet</servlet-class>
        <init-param>
            <param-name>applicationClassName</param-name>
            <param-value>wicket.quickstart.WicketApplication</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>quickstart</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

I would like to configure cache for static resources such as:

/src/webapp/*, i.e.: /src/webapp/images, /src/webapp/css, /src/webapp/js, etc.

What should I add into my web.xml?

解决方案

Need to add the following to your web.xml

<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.mortbay.jetty.servlet.DefaultServlet</servlet-class>
    <init-param>
        <param-name>cacheControl</param-name>
        <param-value>max-age=3600,public</param-value>
    </init-param>
</servlet>
