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>  
    <!-- 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>
