去除HTTPS的j基础认证方式
cas的：deployerConfigContext.xml
<!-- Required for proxy ticket mechanism. -->
<bean id = "proxyAuthenticationHandler" class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"
p:httpClient-ref="httpClient"
p:requireSecure="false"/>
spring-configurationticketGrantingTicketCookieGenerator.xml
<bean id="ticketGrantingTicketCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
p:cookieSecure="false"
p:cookieMaxAge="3600"
p:cookieName="CASTGC"
p:cookiePath="/cas" />
spring-configurationwarnCookieGenerator.xml
<bean id="warnCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
p:cookieSecure="false"
p:cookieMaxAge="3600"
p:cookieName="CASPRIVACY"
p:cookiePath="/cas" />
cas客户端的使用
1.加入cas客户端相关的依赖
<!-- cas -->
<dependency>
<groupId>org.jasig.cas.client</groupId>
<artifactId>cas-client-core</artifactId>
<version>3.3.3</version>
</dependency>
-
单点登出的过滤器
<!-- 用于单点退出，该过滤器用于实现单点登出功能，可选配置 -->
<listener>
<listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>
</listener>
<!-- 该过滤器用于实现单点登出功能，可选配置。 -->
<filter>
<filter-name>CAS Single Sign Out Filter</filter-name>
<filter-class>org.jasig.cas.client.session.SingleSignOutFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CAS Single Sign Out Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
- 认证过滤器
<!-- 该过滤器负责用户的认证工作，必须启用它 -->
<filter>
<filter-name>CASFilter</filter-name>
<filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>
<init-param>
<param-name>casServerLoginUrl</param-name>
<param-value>http://localhost:8099/cas/login</param-value> <!--这里的server是服务端的IP -->
</init-param>
<init-param>
<param-name>serverName</param-name>
<param-value>http://localhost:9002</param-value> <!-- 当前应用的地址 -->
</init-param>
</filter>
<filter-mapping>
<filter-name>CASFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
- 票据校验过滤器
<!-- 该过滤器负责对Ticket的校验工作，必须启用它 -->
<filter>
<filter-name>CAS Validation Filter</filter-name>
<filter-class>org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter</filter-class>
<init-param>
<param-name>casServerUrlPrefix</param-name>
<param-value>http://localhost:8099/cas</param-value> <!--这里的server是服务端的IP -->
</init-param>
<init-param>
<param-name>serverName</param-name>
<param-value>http://localhost:9002</param-value> <!-- 当前应用的地址 -->
</init-param>
</filter>
<filter-mapping>
<filter-name>CAS Validation Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
- 获取登录名所需要的过滤器
<!-- 该过滤器负责实现HttpServletRequest请求的包裹， 比如允许开发者通过HttpServletRequest的getRemoteUser()方法获得SSO登录用户的登录名，可选配置。 -->
<filter>
<filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>
<filter-class>org.jasig.cas.client.util.HttpServletRequestWrapperFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 该过滤器使得开发者可以通过org.jasig.cas.client.util.AssertionHolder来获取用户的登录名。 比如AssertionHolder.getAssertion().getPrincipal().getName()。 -->
<filter>
<filter-name>CAS Assertion Thread Local Filter</filter-name>
<filter-class>org.jasig.cas.client.util.AssertionThreadLocalFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CAS Assertion Thread Local Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
单点退出
退出完毕以后，要跳转到指定的地址，所有需要进行配置
cas的：cas-servlet.xml
<bean id="logoutAction" class="org.jasig.cas.web.flow.LogoutAction"
p:servicesManager-ref="servicesManager"
p:followServiceRedirects="${cas.logout.followServiceRedirects:true}"/>
配置数据源
deployerConfigContext.xml
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
p:driverClass="com.mysql.jdbc.Driver"
p:jdbcUrl="jdbc:mysql://127.0.0.1:3306/pinyougoudb?characterEncoding=utf8" （注：数据库的表名）
p:user="root"
p:password="1234" />(注：此处为数据库客户端的登录账号和密码)
<bean id="passwordEncoder" class="org.jasig.cas.authentication.handler.DefaultPasswordEncoder"
c:encodingAlgorithm="MD5"
p:characterEncoding="UTF-8" />
<bean id="dbAuthHandler" class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler"
p:dataSource-ref="dataSource"
p:sql="select password from tb_user where username = ?"
p:passwordEncoder-ref="passwordEncoder"/>
修改如下的配置
<bean id="authenticationManager" class="org.jasig.cas.authentication.PolicyBasedAuthenticationManager">
<constructor-arg>
<map>
<entry key-ref="proxyAuthenticationHandler" value-ref="proxyPrincipalResolver" />
<entry key-ref="dbAuthHandler" value-ref="primaryPrincipalResolver" />
</map>
</constructor-arg>
<property name="authenticationPolicy">
<bean class="org.jasig.cas.authentication.AnyAuthenticationPolicy" />
</property>
</bean>
认证的配置： <authentication-manager></authentication-manager>
授权的配置： <http></http>
整合的思路： 就是把CAS Client所使用到了的过滤器加入到Spring Security的过滤器链中
1.pom中加入依赖
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-cas</artifactId>
<version>4.1.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.jasig.cas.client</groupId>
<artifactId>cas-client-core</artifactId>
<version>3.3.3</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
</exclusion>
</exclusions>
</dependency>
2.在web.xml文件中去配置DelegatingFilterProxy
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置spring核心监听器ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-security.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
3.修改spring-security的文件
- 入口点的配置： 告诉我们的应用程序，现在要进行认证，请请求CAS完成
<!-- entry-point-ref 入口点引用 -->
<http use-expressions="false" entry-point-ref="casProcessingFilterEntryPoint">
<intercept-url pattern="/**" access="ROLE_USER"/>
<csrf disabled="true"/>
<!-- custom-filter为过滤器， position 表示将过滤器放在指定的位置上，before表示放在指定位置之前 ，after表示放在指定的位置之后 -->
<custom-filter ref="casAuthenticationFilter" position="CAS_FILTER" />
<custom-filter ref="requestSingleLogoutFilter" before="LOGOUT_FILTER"/>
<custom-filter ref="singleLogoutFilter" before="CAS_FILTER"/>
</http>
<!-- CAS入口点 开始 -->
<beans:bean id="casProcessingFilterEntryPoint" class="org.springframework.security.cas.web.CasAuthenticationEntryPoint">
<beans:property name="loginUrl" value="http://localhost:8099/cas/login"/> <!-- 单点登录服务器登录URL -->
<beans:property name="serviceProperties" ref="serviceProperties"/>
</beans:bean>
<beans:bean id="serviceProperties" class="org.springframework.security.cas.ServiceProperties">
<beans:property name="service" value="http://localhost:9003/login/cas"/> <!--service 配置自身工程的根地址+/login/cas -->
</beans:bean>
<!-- CAS入口点 结束 -->
- 认证过滤器
<!-- 认证过滤器 开始 -->
<beans:bean id="casAuthenticationFilter" class="org.springframework.security.cas.web.CasAuthenticationFilter">
<beans:property name="authenticationManager" ref="authenticationManager"/>
</beans:bean>
<!-- 认证管理器 -->
<authentication-manager alias="authenticationManager">
<authentication-provider ref="casAuthenticationProvider"></authentication-provider>
</authentication-manager>
<!-- 认证提供者 -->
<beans:bean id="casAuthenticationProvider" class="org.springframework.security.cas.authentication.CasAuthenticationProvider">
<beans:property name="authenticationUserDetailsService">
<beans:bean class="org.springframework.security.core.userdetails.UserDetailsByNameServiceWrapper">
<beans:constructor-arg ref="userDetailsService" />
</beans:bean>
</beans:property>
<beans:property name="serviceProperties" ref="serviceProperties"/>
<!-- ticketValidator 为票据验证器 -->
<beans:property name="ticketValidator">
<beans:bean class="org.jasig.cas.client.validation.Cas20ServiceTicketValidator">
<beans:constructor-arg index="0" value="http://localhost:8099/cas"/>
</beans:bean>
</beans:property>
<beans:property name="key" value="an_id_for_this_auth_provider_only"/>
</beans:bean>
<!-- 认证类 -->
<beans:bean id="userDetailsService" class="cn.itcast.demo.service.UserDetailServiceImpl"/>
- 退出过滤器
<!-- 认证过滤器 结束 -->
<!-- 单点登出 开始 完成真正的退出-->
<beans:bean id="singleLogoutFilter" class="org.jasig.cas.client.session.SingleSignOutFilter"/>
<!-- 经过此配置，当用户在地址栏输入本地工程 /logout/cas ； 配置了退出地址的映射，目的：为了提高安全性 -->
<beans:bean id="requestSingleLogoutFilter" class="org.springframework.security.web.authentication.logout.LogoutFilter">
<beans:constructor-arg value="http://localhost:8099/cas/logout?service=http://localhost:9003/index2.html"/>
<beans:constructor-arg>
<beans:bean class="org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler"/>
</beans:constructor-arg>
<beans:property name="filterProcessesUrl" value="/logout/cas"/>
</beans:bean>
<!-- 单点登出 结束 -->
