java – 在spring security中禁用特定URL的缓存

在我的情况下,我有四种方法来解决我的问题：

>在我的index.html中编写元配置并禁用缓存(对我不起作用)
>将index.html更改为index.jsp并禁用缓存,如here(为我工作,但我的客户端组需要index.html)
>在web.xml中使用过滤器,区分所需的请求并禁用缓存
>春季安全

我的问题是如何使用Spring Security禁用index.html的缓存
 (也许在http标签中使用intercept-url)

解决方法:

您可以使用Spring Security xml configuartion选择性地仅向index.html添加缓存标头,如下所示：

<security:http>
[intercept-url, etc omitted...]
        <security:headers>
            <!-- selectively applied to dynamic pages only via pattern matching,  -->
            <security:header ref="noCacheHeaders"/>
        </security:headers>
    </security:http>    

<bean id="noCacheHeaders" class="org.springframework.security.web.header.writers.DelegatingRequestMatcherHeaderWriter">
        <constructor-arg>
            <bean class="org.springframework.security.web.util.matcher.AntPathRequestMatcher">
                <constructor-arg value="/index.html"/>
            </bean>
        </constructor-arg>
        <constructor-arg>
                <bean class="org.springframework.security.web.header.writers.CacheControlHeadersWriter"/>
        </constructor-arg>
    </bean>

但是,如果使用Spring Security,通常的模式是默认情况下不为所有页面设置缓存,然后选择性地关闭这些标头以获取静态资源

>不包含敏感数据
>不是动态的

要完成此专长,您必须在两种情况下明确定义要应用的所有标头,并通过补充请求匹配器模式选择页面.例如,在/ static及其子目录下找到静态可缓存资源的应用程序中,以及映射到控制器的所有动态页面都具有.htm扩展名,您可以使用此配置：

        <security:http>
[...]
<security:headers>
            <!-- selectively applied to static pages only via pattern matching, see DelegatingRequestMatcherHeaderWriter below-->
            <security:header ref="cacheStaticsHeaders" />

            <!-- selectively applied to dynamic pages only via pattern matching, as above, see below -->
            <security:header ref="xXssProtectionHeader" />
            <security:header ref="noCacheHeaders"/>
            <security:header ref="xContentHeader"/>
            <security:header ref="hstsHeader"/>
            <security:header ref="xFrameHeader"/>
        </security:headers>

    </security:http>


    <!-- set far future caching on static resources -->
    <bean id="cacheStaticsHeaders" class="org.springframework.security.web.header.writers.DelegatingRequestMatcherHeaderWriter">
        <constructor-arg>
            <bean class="org.springframework.security.web.util.matcher.AntPathRequestMatcher">
                <constructor-arg value="/static/**"/>
            </bean>
        </constructor-arg>
        <constructor-arg>
            <bean class="org.springframework.security.web.header.writers.StaticHeadersWriter">
                <constructor-arg name="headers">
                    <list>
                        <bean class="org.springframework.security.web.header.Header">
                            <constructor-arg name="headerName" value="cache-control"></constructor-arg>
                            <constructor-arg name="headerValues" value="max-age=31536000"/>
                        </bean>
                        <bean class="org.springframework.security.web.header.Header">
