Question

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here之类的缓存（为我工作，但我的客户群需要index.html）
使用web.xml中的过滤器并区分所需请求并禁用缓存
Spring Security

我的问题是如何使用Spring Security禁用index.html的缓存（可能在intercept-url代码中使用http

Answer 1

您可以使用Spring Security xml configuartion选择性地不向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，然后选择关闭这些标头以获取静态资源

不包含敏感数据
不动态

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>

                        </bean>
                        <bean class="org.springframework.security.web.header.Header">
