使用 WebContentInterceptor 为 spring mvc 3 的不同部分设置不缓存?
您好,我开发了一个动态 Web 应用程序,它使用 Ajax 从数据库获取数据并使 GUI 保持最新,但在使用 IE8 测试它时,我遇到了缓存问题。
我在 webmvc-config.xml 文件中使用以下代码来阻止浏览器缓存:
它的工作方式完全符合预期,但问题是现在浏览器显然不缓存任何内容。我想知道的是如何修改该 xml 代码,以便它适用于 Web 应用程序的 Ajax 部分(使用 5 个控制器文件进行控制);这样图标..等仍然被缓存?这些控制器文件的路径类似于“/admin/**”
我知道Spring WebContentInterceptor具有诸如“setCacheMappings”和“setPathMatcher”之类的属性,但是在网上我找不到这些属性的示例xml 配置文件。
任何帮助将不胜感激,这真的让我很头疼……谢谢。杰克
Hi there I have developed a dynamic web application that uses Ajax to fetch data from databases and keep the GUI up to date but while testing it with IE8 I am experiencing caching issues.
I used the following code in my webmvc-config.xml file to stop the browser from caching:
<mvc:annotation-driven />
<mvc:interceptors>
<bean id="webContentInterceptor"
class="org.springframework.web.servlet.mvc.WebContentInterceptor">
<property name="cacheSeconds" value="0"/>
<property name="useExpiresHeader" value="true"/>
<property name="useCacheControlHeader" value="true"/>
<property name="useCacheControlNoStore" value="true"/>
</bean>
</mvc:interceptors>
and it works exactly as it should, but the problem is that now the browser obviously doesn't cache anything. what I want to know is how to modify that xml code so that it applies to the Ajax parts of the web app (which are controlled using 5 Controller files); so that the icons..etc are still cached? The path to these controller files would be something like "/admin/**"
I know that the Spring WebContentInterceptor has properties such as "setCacheMappings" and "setPathMatcher" but there is nowhere online that I can find examples of these being using in the xml config file.
ANY help would be much appreciated, it's really doing my head in.. Thanks. Jake
