spring-security - 将 security=none 应用于上下文根和静态资源 : spring security version 3. 1

Question

我的应用程序编译为 ROOT.war，这基本上意味着我没有除/之外的上下文根。有些页面需要保护；但是有些 URL 不需要它；例如我的 http://localhost:8080/给出这个应用程序的主页；并且有类似的页面，例如关于我们、联系我们等不需要安全性的页面。所以我将其添加到配置中

  <security:intercept-url pattern="/" access="permitAll" />
  <security:intercept-url pattern="/resources/**" access="permitAll" />
  <security:intercept-url pattern="/register/confirm" access="isAuthenticated()" />
  <security:intercept-url pattern="/register/accept" access="isAuthenticated()" />
  <security:intercept-url pattern="/shopper/**" access="isAuthenticated()" />

但这只是说用户可以“无需身份验证”访问这些 URL，如果您访问这些 URL，安全过滤器将全部应用，如下面的调试日志所示

当我尝试使用此配置时(按下面提到的顺序):

 <!-- No Security required for the ROOT Context -->
  <security:http pattern="/**" security="none" />

 <!-- Apply secyrity for shopper URLs -->
 <security:http auto-config="true" use-expressions="true" access-denied-page="/denied">
  <security:intercept-url pattern="/" access="permitAll" />
  <security:intercept-url pattern="/resources/**" access="permitAll" />
  <security:intercept-url pattern="/register/confirm" access="isAuthenticated()" />
  <security:intercept-url pattern="/register/accept" access="isAuthenticated()" />
  <security:intercept-url pattern="/shopper/**" access="isAuthenticated()" /
 ....
  </security:http>

<security:http pattern="/resources/**" security="none" />

它崩溃给出错误

Please check the ordering in your <security:http> namespace or FilterChainProxy bean configuration

我真的无法理解这背后的原因。我必须实现自己的请求模式匹配器吗？

解决方案

 <beans:bean id="filterChainProxy" class="org.springframework.security.web.FilterChainProxy" >
 <beans:constructor-arg>
  <beans:list>
   <security:filter-chain pattern="/resources/**"
    filters="none" />
   <security:filter-chain pattern="/aboutus"
    filters="none" />   
   <security:filter-chain pattern="/contactus"
    filters="none" />
   <security:filter-chain pattern="/news"
    filters="none" />    
  </beans:list>
 </beans:constructor-arg>
</beans:bean>

Answer 1

具有模式 /** 的

security="none" 捕获所有 URL，因此无法应用其他规则。为什么您在第二个示例中收到错误。

但是可以为不同的 URL 模式定义不同的 filter-chains。我没有使用新语法的示例，但这是使用旧语法的示例(filter-chains 的顺序很重要):

<bean id="springSecurityFilterChain" class="org.springframework.security.web.FilterChainProxy">
    <sec:filter-chain-map path-type="ant">
        <sec:filter-chain pattern="/dwr/**" filters="securityContextPersistenceFilter,securityContextHolderAwareRequestFilter,rememberMeAuthenticationFilter,anonymousAuthenticationFilter" />
        <sec:filter-chain pattern="/**" filters="channelProcessingFilter,securityContextPersistenceFilter,logoutFilter,authenticationFilter,securityContextHolderAwareRequestFilter,rememberMeAuthenticationFilter,anonymousAuthenticationFilter,sessionManagementFilter,exceptionTranslationFilter,filterSecurityInterceptor,switchUserProcessingFilter" />
    </sec:filter-chain-map>
</bean>
