spring security 学习笔记

spring security 学习笔记 springframework.security几个关键类及结构

• 1.org.springframework.security.web.access.interceptFilterSecurityInterceptor

  • Filter
    • doFilter
      • FilterInvocation.invoke
        • beforeInvocation
          • SecurityContextHolder.getContext().getAuthentication()
          • authenticationManager.authenticate(authentication)
          • accessDecisionManager.decide(authenticated, object, attributes)
        • getChain().doFilter
        • afterInvocation
          • afterInvocationManager.decide(token.getSecurityContext().getAuthentication(), token.getSecureObject(), token.getAttributes(), returnedObject)
  • AbstractSecurityInterceptor
    • AuthenticationManager
    • AfterInvocationManager
      • AfterInvocationProviderManager
    • AccessDecisionManager
      • AbstractAccessDecisionManager
        • Affirmativebased
        • Consensusbased
        • Unanimousbased

• 2.org.springframework.security.access.intercept.aopalliance.MethodSecurityInterceptor

  • org.aopalliance.intercept.MethodInterceptor
    • org.aopalliance.aop.Advice.Interceptor
      • org.aopalliance.aop.Advice
  • AbstractSecurityInterceptor

• 3.org.springframework.security.access.intercept.aspectj.AspectJMethodSecurityInterceptor

  • MethodInterceptor

• 4.AuthenticationEntryPoint,主要是commence方法统一异常，由用户自定义实现

• 5.AuthenticationManager, 用于验证，Processes an Authentication request

spring security过滤器设置先后顺序

FilterComparator 设置过滤器执行链

 FilterComparator.Step order = new FilterComparator.Step(100, 100);
 this.put(ChannelProcessingFilter.class, order.next());
 this.put(ConcurrentSessionFilter.class, order.next());
 this.put(WebAsyncManagerIntegrationFilter.class, order.next());
 this.put(SecurityContextPersistenceFilter.class, order.next());
 this.put(HeaderWriterFilter.class, order.next());
 this.put(CorsFilter.class, order.next());
 this.put(CsrfFilter.class, order.next());
 this.put(LogoutFilter.class, order.next());
 this.filterToOrder.put("org.springframework.security.oauth2.client.web.OAuth2AuthorizationRequestRedirectFilter", order.next());
 this.filterToOrder.put("org.springframework.security.saml2.provider.service.servlet.filter.Saml2WebSsoAuthenticationRequestFilter", order.next());
 this.put(X509AuthenticationFilter.class, order.next());
 this.put(AbstractPreAuthenticatedProcessingFilter.class, order.next());
 this.filterToOrder.put("org.springframework.security.cas.web.CasAuthenticationFilter", order.next());
 this.filterToOrder.put("org.springframework.security.oauth2.client.web.OAuth2LoginAuthenticationFilter", order.next());
 this.filterToOrder.put("org.springframework.security.saml2.provider.service.servlet.filter.Saml2WebSsoAuthenticationFilter", order.next());
 this.put(UsernamePasswordAuthenticationFilter.class, order.next());
 this.put(ConcurrentSessionFilter.class, order.next());
 this.filterToOrder.put("org.springframework.security.openid.OpenIDAuthenticationFilter", order.next());
 this.put(DefaultLoginPageGeneratingFilter.class, order.next());
 this.put(DefaultLogoutPageGeneratingFilter.class, order.next());
 this.put(ConcurrentSessionFilter.class, order.next());
 this.put(DigestAuthenticationFilter.class, order.next());
 this.filterToOrder.put("org.springframework.security.oauth2.server.resource.web.BearerTokenAuthenticationFilter", order.next());
 this.put(BasicAuthenticationFilter.class, order.next());
 this.put(RequestCacheAwareFilter.class, order.next());
 this.put(SecurityContextHolderAwareRequestFilter.class, order.next());
 this.put(JaasApiIntegrationFilter.class, order.next());
 this.put(RememberMeAuthenticationFilter.class, order.next());
 this.put(AnonymousAuthenticationFilter.class, order.next());
 this.filterToOrder.put("org.springframework.security.oauth2.client.web.OAuth2AuthorizationCodeGrantFilter", order.next());
 this.put(SessionManagementFilter.class, order.next());
 this.put(ExceptionTranslationFilter.class, order.next());
 this.put(FilterSecurityInterceptor.class, order.next());
 this.put(SwitchUserFilter.class, order.next());

oauth2关键类

• OAuth2AuthenticationProcessingFilter OAuth2的Filter
  • doFilter
    • tokenExtractor.extract
    • authenticationManager.authenticate
    • 成功，publishAuthenticationSuccess和SecurityContextHolder.getContext().setAuthentication
    • 失败，authenticationEntryPoint.commence
• OAuth2AuthenticationManager
  • ResourceServerTokenServices
    • DefaultTokenServices 实现类
      • loadAuthentication 方法
      • readAccessToken 方法
      • TokenStore 依赖
        • RedisTemplateTokenStore 实现类
          • getAccessToken 方法
          • removeRefreshToken 方法
          • removeAccessToken 方法
  • ClientDetailsService
    • RedisClientDetailsService，在Redis中缓存JdbcClientDetailsService维护的ClientDetails
    • JdbcClientDetailsService ，ClientDetails最终存储于数据库中
• BearerTokenExtractor
• OAuth2AuthenticationEntryPoint,统一的异常处理类
