• 品优购商城项目(六)CAS客户端与SpringSecurity集成


    cas单点登录旨在解决传统登录模式session在分布式项目中共享登录信息的问题。

    本文cas服务器使用 4.0版本,仅供学习参考。把 cas.war 直接部署在tomcat即可,这里有个固定的用户名和密码   casuser /Mellon

    修改密码在 cas/WEB-INF/deployerConfigContext.xml

    <bean id="primaryAuthenticationHandler"
              class="org.jasig.cas.authentication.AcceptUsersAuthenticationHandler">
            <property name="users">
                <map>
                    <entry key="casuser" value="Mellon"/>
                    <entry key="admin" value="123456"/>
                </map>
            </property>
        </bean>

    需要重启tomcat才能失效

    一、 CAS服务端配置

    1、端口修改

    如果我们不希望用8080端口访问CAS, 可以修改端口

    (1)修改TOMCAT的端口

    打开tomcat 目录 confserver.xml  找到下面的配置

     

    将端口8080,改为9100

    (2)修改CAS配置文件(直接修改tomcat部署的cas)

    修改cas的WEB-INF/cas.properties

    server.name=http://localhost:9100

    2、去除https认证

    CAS默认使用的是HTTPS协议,如果使用HTTPS协议需要SSL安全证书(需向特定的机构申请和购买) 。如果对安全要求不高或是在开发测试阶段,可使用HTTP协议。我们这里讲解通过修改配置,让CAS使用HTTP协议。

    (1)修改cas的WEB-INF/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"/>

    这里需要增加参数p:requireSecure="false",requireSecure属性意思为是否需要安全验证,即HTTPS,false为不采用

    (2)修改cas的/WEB-INF/spring-configuration/ticketGrantingTicketCookieGenerator.xml

    <bean id="ticketGrantingTicketCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
            p:cookieSecure="false"
            p:cookieMaxAge="3600"
            p:cookieName="CASTGC"
            p:cookiePath="/cas" />

    参数p:cookieSecure="true",同理为HTTPS验证相关,TRUE为采用HTTPS验证,FALSE为不采用https验证。

    参数p:cookieMaxAge="-1",是COOKIE的最大生命周期,-1为无生命周期,即只在当前打开的窗口有效,关闭或重新打开其它窗口,仍会要求验证。可以根据需要修改为大于0的数字,比如3600等,意思是在3600秒内,打开任意窗口,都不需要验证。我们这里将cookieSecure改为false ,  cookieMaxAge 改为3600

    (3)修改cas的WEB-INF/spring-configuration/warnCookieGenerator.xml

    <bean id="warnCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
            p:cookieSecure="false"
            p:cookieMaxAge="3600"
            p:cookieName="CASPRIVACY"
            p:cookiePath="/cas" />

    我们这里将cookieSecure改为false ,  cookieMaxAge 改为3600

     (4)登出跳转的配置 ,修改 cas 系统的配置文件 cas-servlet.xml

    <bean id="logoutAction" class="org.jasig.cas.web.flow.LogoutAction"
    p:servicesManager-ref="servicesManager"
    p:followServiceRedirects="${cas.logout.followServiceRedirects:true}"/>

    改为 true 后,可以在退出时跳转页面到目标页面,修改 index.jsp 的退出链接

    <a href="http://localhost:9100/cas/logout?service=http://www.baidu.com">退出登录</a>

    二、CAS集成数据库

     达到用户登录从数据库验证账号密码的目的。

    (1)修改cas服务端中web-inf下deployerConfigContext.xml ,添加如下配置

    <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"
                  p:user="root"
                  p:password="123456" />
    <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"/>

    然后在配置文件开始部分找到 bean authenticationManager 修改

    <bean id="authenticationManager" class="org.jasig.cas.authentication.PolicyBasedAuthenticationManager">
            <constructor-arg>
                <map>
                    <!--
                       | IMPORTANT
                       | Every handler requires a unique name.
                       | If more than one instance of the same handler class is configured, you must explicitly
                       | set its name to something other than its default name (typically the simple class name).
                       -->
                    <entry key-ref="proxyAuthenticationHandler" value-ref="proxyPrincipalResolver" />
                    <!--<entry key-ref="primaryAuthenticationHandler" value-ref="primaryPrincipalResolver" />-->
                    <entry key-ref="dbAuthHandler" value-ref="primaryPrincipalResolver"/>
                </map>
            </constructor-arg>

    其中<entry key-ref="primaryAuthenticationHandler" value-ref="primaryPrincipalResolver" />一句是使用固定的用户名和密码,我们在下面可以看到这两个bean ,如果我们使用数据库认证用户名和密码,需要将这句注释掉。添加<entry key-ref="dbAuthHandler" value-ref="primaryPrincipalResolver"/>使用数据库数据验证

    (2)将以下三个jar包放入webappscasWEB-INFlib下 

     重启tomcat 登录

    三、CAS服务端界面改造

     主要修改cas默认的登录等页面,用自己的页面。

    1、拷贝资源

    (1)将品优购的登陆页login.html 拷贝到cas系统下WEB-INFviewjspdefaultui 目录下,将 css 、js、img等文件夹拷贝合并到 cas 目录下

    (2) 将原来的casLoginView.jsp 改名(可以为之后的修改操作做参照),将login.html改名为casLoginView.jsp

    2、修改页面casLoginView.jsp 内容

    (1)添加指令

    <%@ page pageEncoding="UTF-8" %>
    <%@ page contentType="text/html; charset=UTF-8" %>
    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
    <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
    <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
    <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

    (2)修改form标签

    <form:form method="post" id="fm1" commandName="${commandName}" htmlEscape="true" class="sui-form">
    ......
    </form:form>

    (3)修改用户名框

    <form:input id="username" tabindex="1"
        accesskey="${userNameAccessKey}" path="username" autocomplete="off" htmlEscape="true"
        placeholder="邮箱/用户名/手机号" class="span2 input-xfat" />

    (4)修改密码框

    <form:password  id="password" tabindex="2" path="password"
          accesskey="${passwordAccessKey}" htmlEscape="true" autocomplete="off"
          placeholder="请输入密码" class="span2 input-xfat"   />

    (5)修改登陆按钮

    <input type="hidden" name="lt" value="${loginTicket}" />
    <input type="hidden" name="execution" value="${flowExecutionKey}" />
    <input type="hidden" name="_eventId" value="submit" />
    <input class="sui-btn btn-block btn-xlarge btn-danger" accesskey="l" value="登陆" type="submit" />

    3、错误提示

    (1)在表单内加入错误提示框

    <form:errors path="*" id="msg" cssClass="errors" element="div" htmlEscape="false" />

    (2)修改错误提示信息为中文

    这个提示信息是在WEB-INFclasses目录下的messages.properties文件中,错误信息可以自定义,记得转成unicode编码

    #用户不存在,信息可以自定义转unicode防止中文乱码
    authenticationFailure.AccountNotFoundException=u7528u6237u4E0Du5B58u5728
    #密码错误同上
    authenticationFailure.FailedLoginException=u5BC6u7801u9519u8BEF

    设置国际化为zn_CN  ,修改WEB-INF/cas-servlet.xml

     <!-- Locale Resolver -->
      <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" p:defaultLocale="zh_CN" />

     

    四、CAS客户端与SpringSecurity集成

    1、用户中心实现单点登录

    (1)pom.xml 引入springSecurity、cas客户端和springSecurity Cas整合包依赖

     <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>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)将用户中心相关的页面(home-开头的)拷贝至  pinnyougou-user-web

    (3)web.xml  添加spring-security过滤器,设置首页为home-index.html

    <welcome-file-list>
            <welcome-file>home-index.html</welcome-file>
        </welcome-file-list>

    (4)构建UserDetailsServiceImpl.java  

    import org.springframework.security.core.GrantedAuthority;
    import org.springframework.security.core.authority.SimpleGrantedAuthority;
    import org.springframework.security.core.userdetails.User;
    import org.springframework.security.core.userdetails.UserDetails;
    import org.springframework.security.core.userdetails.UserDetailsService;
    import org.springframework.security.core.userdetails.UsernameNotFoundException;
    import java.util.ArrayList;
    import java.util.List;
    
    public class UserDetailServiceImpl implements UserDetailsService {
    
        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
            System.out.println("经过认证类:"+username);
            
            List<GrantedAuthority> authorities=new ArrayList();
            authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
            
            return new User(username,"",authorities);
        }
    
    }

    (5)添加spring-security.xml,并做以下修改

    配置匿名访问资源

    <?xml version="1.0" encoding="UTF-8"?>
    <beans:beans xmlns="http://www.springframework.org/schema/security"
        xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <beans:bean id="serviceProperties" class="org.springframework.security.cas.ServiceProperties">  
            <!--service 配置自身工程的根地址+/login/cas   -->  
            <beans:property name="service" value="http://localhost:9106/login/cas"/>
        </beans:bean>  
        <!-- CAS入口点 结束 -->
    
        
        <!-- 认证过滤器 开始 -->

            </beans:property>  
            <beans:property name="serviceProperties" ref="serviceProperties"/>  
            <!-- ticketValidator 为票据验证器 -->

        <!-- 经过此配置,当用户在地址栏输入本地工程 /logout/cas  -->      
        <beans:bean id="requestSingleLogoutFilter" class="org.springframework.security.web.authentication.logout.LogoutFilter">  
            <beans:constructor-arg value="http://localhost:9100/cas/logout?service=http://localhost:9103"/>  
            <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 -->  
        
    </beans:beans>
    View Code

    2、页面显示用户名

    (1)pinyougou-user-web创建LoginController.java

    import org.springframework.security.core.context.SecurityContextHolder;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import java.util.HashMap;
    import java.util.Map;
    
    @RestController
    @RequestMapping("/login")
    public class LoginController {
    
        @RequestMapping("/name")
        public Map showName(){
            String name = SecurityContextHolder.getContext().getAuthentication().getName();
            Map map=new HashMap();
            map.put("loginName", name);
            return map;        
        }
        
    }

    (2)创建loginService.js

    //服务层
    app.service('loginService',function($http){
        //读取列表数据绑定到表单中
        this.showName=function(){
            return $http.get('../login/name.do');
        }
    });

    (3)创建indexController.js

    //首页控制器
    app.controller('indexController',function($scope,loginService){
        $scope.showName=function(){
                loginService.showName().success(
                        function(response){
                            $scope.loginName=response.loginName;
                        }
                );
        }
    });

    (4)修改home-index.html  引入js

    <scripttype="text/javascript"src="plugins/angularjs/angular.min.js"></script>
        <scripttype="text/javascript"src="js/base.js"></script>    
        <scripttype="text/javascript"src="js/service/loginService.js"></script>
        <scripttype="text/javascript"src="js/controller/indexController.js"></script>

    指令,调用方法查询登陆名

    <bodyng-app="pinyougou"ng-controller="indexController"ng-init="showName()">

    显示用户名

    <spanclass="name">{{loginName}}</span>

    3、退出登录

    spring-security.xml设置退出登录后的跳转地址

    <!-- 经过此配置,当用户在地址栏输入本地工程 /logout/cas  -->      
        <beans:bean id="requestSingleLogoutFilter" class="org.springframework.security.web.authentication.logout.LogoutFilter">  
            <beans:constructor-arg value="http://localhost:9100/cas/logout?service=http://localhost:9103"/>  
            <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>  

    页面

    <span class="safe"><a href="logout/cas">退出登录 </a></span>
