Spring Security的filter配置及说明

阅读更多

以前在PA关注过用户登录授权的过程,看过JAAS的规范,看过WEBLOGIC的实现代码,看过Spring Security的源代码,这么久都忘了。。现在开始,把以前丢掉的技术日记能记得记下来,以后也开始写日记了~~:)

验证

使用 opends ldap 数据库,(运行的脚本在该目录的 ldap.ldif 下)

上下文参数:

http://localhost:389

o=company.com.cn

cn=orcladmin

pwd: hhxxttxs

 



 

创建 ou 用的 opends 的图形工具创建, groups 下面的条目用 ldif 导入创建的, ldif 如下:

dn:cn=staffRole,ou=groups,o= company.com.cn

objectClass:groupOfUniqueNames

cn:staffRole

uniquemember:uid=zhuoyueping790,ou=staff,ou=people,o= company.com.cn

 

dn:cn=clientRole,ou=groups,o= company.com.cn

objectClass:groupOfUniqueNames

cn:clientRole

uniquemember:uid=chenshengli532,ou=client,ou=people,o= company.com.cn

staffRole 角色的用户可以访问 /staff.* 资源;

clientRole 角色的用户可以访问 /client.* 资源

 

例子中所有密码均为: hhxxttxs

所有标有页数的地方为《敏捷 Acegi CAS ——构建安全的 java 系统》的页码。

红色 表示待解决的问题,蓝色 表示有特别说明或者代码解释的语句。

该项目的全部文件(包括 jar 包,在该目录下的 ss 目录中)

斜体 bena 的名字 表示即将要解释的调用的 bean.

1 》:org.springframework.web.context.ContextLoaderListener

( 该类在 spring-web.jar 包中, )

2 》:org.springframework.util.FilterToBeanProxy: 如果配置了targetBeantargetClass, 优先调用targetHean. 推荐使用targetHean 的方式。

通过调用FilterToBeanProxyinit ()方法启动过滤器链工作。

( org.springframework.security.* 的类都 spring-security-core.jar 包中, )

 

public class FilterToBeanProxy implements Filter{

public void init(FilterConfig filterConfig) throws ServletException {

    this.filterConfig = filterConfig;

    String strategy = filterConfig.getInitParameter("init");

    if ((strategy != null) && (strategy.toLowerCase().equals("lazy"))) {

      return;

   }

    doInit();

  }

}

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)

   throws IOException, ServletException

  {

     if (!(this.initialized)) {

       doInit();

     }

}

 

private synchronized void doInit() throws ServletException {

//…

    String targetBean = this.filterConfig.getInitParameter("targetBean");

// 关于 lifecircle 部分,先放在这里以后补充   

String lifecycle = this.filterConfig.getInitParameter("lifecycle");

    if ("servlet-container-managed".equals(lifecycle)) {

      this.servletContainerManaged = true;

    }

    ApplicationContext ctx = getContext(this.filterConfig);

String beanName = null;

 

   if ((targetBean != null) && (ctx.containsBean(targetBean))) {

      beanName = targetBean;

    }

  else

  {

       Class targetClass;

      if (targetBean != null) {

       throw new ServletException("targetBean '" + targetBean + "' not found in context");

      }

      String targetClassString = this.filterConfig.getInitParameter("targetClass");

//…      

targetClass= Thread.currentThread().getContextClassLoader().loadClass(targetClassString);

//..

     this.initialized = true;

// 得到代理类,代理类必须是 filter 类,调用代理类的 init ()

Object object = ctx.getBean(beanName);

if (!(object instanceof Filter)) {

      throw new ServletException("Bean '" + beanName + "' does not implement javax.servlet.Filter");

     }

     this.delegate = ((Filter)object);

   if (this.servletContainerManaged) {

 

// 启动代理 filter init 方法

     this.delegate.init(this.filterConfig);

     }

  }

 

 

/WEB-INF/applicationContextsecurity.xml

配置 bean filterChainProxy

<bean id="filterChainProxy"

        class="org.springframework.security.util.FilterChainProxy "> 3

        <property name="filterInvocationDefinitionSource "> 4

            <value>

                PATTERN_TYPE_APACHE_ANT     /**=httpSessionContextIntegrationFilter,authenticationProcessingFilter,exceptionTranslationFilter,filterInvocationInterceptor

            </value>

        </property>

</bean>

4 》给该参数配置过滤器链。

3org.springframework.security.util.FilterChainProxy

/** 表示要过该链的urlall

public class FilterChainProxy   implements Filter, InitializingBean, ApplicationContextAware{

public void init (FilterConfig filterConfig) throws ServletException

  {

   Filter[] filters = obtainAllDefinedFilters();

    for (int i = 0; i < filters.length; ++i)

            filters[i].init(filterConfig);// 依次调用每个 filter 的过滤器链

      }

  }

}

//destroy 也相同,调用每个 filter destroy

 

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)

    throws IOException, ServletException

   {

   FilterInvocation fi = new FilterInvocation(request, response, chain);

    List filters = getFilters(fi.getRequestUrl());

    if ((filters == null) || (filters.size() == 0)) {

        chain.doFilter(request, response);

      return;

}

virtualFilterChain virtualFilterChain = new VirtualFilterChain(fi, filters, null);

virtualFilterChain.doFilter(fi.getRequest(), fi.getResponse());

}

}

 

下面依次是过滤器链中的过滤器。

 

配置 bean httpSessionContextIntegrationFilter

集成过滤器 P49, 如名字所示,将httpSessionsecurityContext 中的认证信息同步。

       <bean id="httpSessionContextIntegrationFilter"

       class="org.springframework.security.context.HttpSessionContextIntegrationFilter "> 5

              <property name="allowSessionCreation " value="false" /> 6

       </bean>

5 HttpSessionContextIntegrationFilter 继承 SpringSecurityFilter SpringSecurityFilter 实现了接口 filter ,在 SpringSecurityFilter 【附 1 】的 doFilter 方法中调用了 doFilterHttp ,子类在 doFilterHttp 中实现自己的逻辑,该过滤器应该放在所有过滤器之前。

6 allowSessionCreation 是否创建 HTTP session

public class HttpSessionContextIntegrationFilter extends SpringSecurityFilter

  implements InitializingBean{

public void doFilterHttp (HttpServletRequest request, HttpServletResponse response,

FilterChain chain){

public void doFilterHttp(HttpServletRequest request, HttpServletResponse response, FilterChain chain)   throws IOException, ServletException

{

// 进入该过滤器器,从 session 中取认证相关信息,放在 SecurityContext 中。

SecurityContext contextBeforeChainExecution = readSecurityContextFromSession(httpSession);

SecurityContextHolder.setContext(contextBeforeChainExecution);

 // 继续执行过滤器链,因此,该过滤器应该放在所有过滤器之前!

chain.doFilter(request, responseWrapper);

 

//…

// finally 中执行,退出出这个过滤器(也是该过滤器链执行完后)前执行。

// contextAfterChainExecution 存最新的 SecurityContext

SecurityContext contextAfterChainExecution = SecurityContextHolder.getContext();

 

SecurityContextHolder.clearContext();// 清除当前线程中的 SecurityContext 相关信息。

request.removeAttribute("__spring_security_session_integration_filter_applied");

// contextAfterChainExecution 修改过的 securitycontext 放在 HTTP session 对象中

if (!(responseWrapper.isSessionUpdateDone())) {

storeSecurityContextInSession(contextAfterChainExecution , request,

httpSessionExistedAtStartOfRequest,

contextHashBeforeChainExecution);

     }

}

}

 

 

 

配置 bean authenticationProcessingFilter

1 楼 confident_f 2011-12-26  
你的生活很丰富呢,我想问一下,假如有两个不同的地址,对应的过滤器链也不一样,
就像这样吧。
  /b/**=httpSessionContextIntegrationFilter,authenticationProcessingFilter,exceptionTranslationFilter,filterInvocationInterceptor

另一个是
  /a/**=httpSessionContextIntegrationFilter,basicProcessingFilter,exceptionTranslationFilter,filterInvocationInterceptor
这样是不是我访问a
时登录了,再访问b还是需要再登录一遍?
