cas.专业解决分布式的session共享问题.没啥好说,目前也没啥解决单点登录的更好的解决方案.
maven坐标:
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.jier.demo</groupId> <artifactId>Security_cas</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <properties> <spring.version>4.2.4.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>4.1.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>4.1.0.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <!--security整合cas--> <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> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.0</version> <configuration> <port>9110</port> <path>/</path> </configuration> </plugin> </plugins> </build> </project>
cas用起来也方便..扔进tomcat就能跑.
配置:没有SSL证书的需要先去关闭hppts认证.
首先是deployerConfigContext中的设置,在最后加上 proxyAuthenticationHandler 中加上requireSecure="false
<!-- Required for proxy ticket mechanism. --> <bean id="proxyAuthenticationHandler" class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler" p:httpClient-ref="httpClient" p:requireSecure="false" />
然后是spring-configuration/ticketGrantingTicketCookieGenerator中把cookieSecure改为不启用,把cookie的声明周期改为3600秒.当然..更长更短都可以
<bean id="ticketGrantingTicketCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator" p:cookieSecure="false " p:cookieMaxAge="3600" p:cookieName="CASTGC" p:cookiePath="/cas" />
最后是:spring-configuration/warnCookieGenerator中的 和上面差不多.(所以说为啥不用springboot.....)
<bean id="warnCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator" p:cookieSecure="false" p:cookieMaxAge="3600" p:cookieName="CASPRIVACY" p:cookiePath="/cas" />
数据源设置:导入将要使用的连接池和数据库连接用的jar包 在deployerConfigContext中写入数据源 更改默认的写死的用户名密码登陆 ,
<bean id="dataSource" class="使用的连接池" p:driverClass="com.mysql.jdbc.Driver" p:jdbcUrl="数据库地址?characterEncoding=utf8" p:user="账号" p:password="密码" /> <bean id="passwordEncoder" class="org.jasig.cas.authentication.handler.DefaultPasswordEncoder" c:encodingAlgorithm="加密方式" p:characterEncoding="UTF-8" /> <bean id="dbAuthHandler" class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler" p:dataSource-ref="dataSource" p:sql="select password from 存用户密码的表名称 where username = ?" p:passwordEncoder-ref="passwordEncoder"/>
<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"/>
<entry key-ref="primaryAuthenticationHandler" value-ref="primaryPrincipalResolver" />
</map>
</constructor-arg>
<property name="authenticationPolicy">
<bean class="org.jasig.cas.authentication.AnyAuthenticationPolicy" />
</property>
</bean>
这样cas就可以连接上数据库根据数据库中的字段来进行登录认证了
注意
<entry key-ref="primaryAuthenticationHandler" value-ref="primaryPrincipalResolver" />
#是使用固定的用户名和密码登陆需要改成
<entry key-ref="dbAuthHandler" value-ref="定义的bean"/>
由于cas默认的登陆页面是jsp页面,需要对jsp页面进行改造才能达到自定义登陆页面的目的 将ui目录下的casLoginView.jsp替换变可以(注意匹配JSP代码)
cas设置好以后需要设置security的配置文件,加入入口点引用,重新设置过滤器,认证管理器,和认证提供者 如果需要单点登出功能,还需要设置单点登出,和登出跳转路径 并且在cas的设置中将cas-servlet中
<bean id="logoutAction" class="org.jasig.cas.web.flow.LogoutAction"
p:servicesManager-ref="servicesManager"
p:followServiceRedirects="${cas.logout.followServiceRedirects:true}"/>
