1. 下载地址 https://github.com/apereo/cas/archive/v4.2.7.zip

2. 解压后，用intellj idea 打开

3. 执行 gradle build -x test ,打包编译

4. 取消https，能够支持直接http

cas.properties 修改两个地方

# Decides whether SSO cookie should be created only under secure connections.
 tgc.secure=false

# The expiration value of the SSO cookie
# tgc.maxAge=-1

# The name of the SSO cookie
# tgc.name=TGC

# The path to which the SSO cookie will be scoped
# tgc.path=/cas

# The expiration value of the SSO cookie for long-term authentications
# tgc.remember.me.maxAge=1209600

# Decides whether SSO Warning cookie should be created only under secure connections.
 warn.cookie.secure=false

casLoginView.jsp

<jsp:directive.include file="includes/top.jsp" />

<%--<c:if test="${not pageContext.request.secure}">
    <div id="msg" class="errors">
        <h2><spring:message code="screen.nonsecure.title" /></h2>
        <p><spring:message code="screen.nonsecure.message" /></p>
    </div>
</c:if>--%>

注销上面的代码

HTTPSandIMAPS-10000001.json 中增加http的service

{
  "@class" : "org.jasig.cas.services.RegexRegisteredService",
  "serviceId" : "^(https|imaps|http)://.*",
  "name" : "HTTPS and IMAPS",
  "id" : 10000001,

    "@class" : "org.jasig.cas.services.RefuseRegisteredServiceProxyPolicy"

    "@class" : "org.jasig.cas.services.DefaultRegisteredServiceUsernameProvider"
  },
  "logoutType" : "BACK_CHANNEL",
  "attributeReleasePolicy" : {
    "@class" : "org.jasig.cas.services.ReturnAllowedAttributeReleasePolicy",
    "principalAttributesRepository" : {
      "@class" : "org.jasig.cas.authentication.principal.DefaultPrincipalAttributesRepository"
    },
    "authorizedToReleaseCredentialPassword" : false,
    "authorizedToReleaseProxyGrantingTicket" : false
  },
  "accessStrategy" : {
    "@class" : "org.jasig.cas.services.DefaultRegisteredServiceAccessStrategy",
    "enabled" : true,
    "ssoEnabled" : true
  }
}

5. 修改cas的认证方式，包括jdbc、自定义密码加密等

5.1 修改 cas-server-webapp 的依赖，修改该工程下build.gradle

5.2 修改cas.properties

 cas.jdbc.authn.query.sql=SELECT username,pwd,salt,`status` FROM sys_user WHERE username = ?
 cas.jdbc.authn.search.password=root
 cas.jdbc.authn.search.user=root

5.3 自定义密码加密 CustomEncoder

8. 打war包，复制到tomcat下启动，或者直接用idea运行

到这里cas安装修改完成了，接下来是修改springboot+shiro + cas(重点部分，已经用红色标出)

9. 加入shiro-cas依赖

compile ("org.apache.shiro:shiro-cas:1.3.2")

10. 修改 ShiroConfiguration.java 自定义cas filter

@Bean
    public CasFilter casFilter() {
        CasFilter casFilter = new CasFilter();
        casFilter.setFailureUrl("/error/403");
        casFilter.setSuccessUrl("/");
        return casFilter;
    }

11. 自定义 cas realm

@Bean
    public MyCasRealm myCasRealm(RetryLimitHashedCredentialsMatcher credentialsMatcher) {
        MyCasRealm casRealm = new MyCasRealm();
        casRealm.setCachingEnabled(true);

        casRealm.setCasServerUrlPrefix("http://localhost:8080/cas");
        casRealm.setCasService("http://localhost:8000/shiro-cas");

        return  casRealm;
    }

12. 自定义多点登出逻辑，不能使用shiro自带的logout filter

14. 修改完成以后，直接访问自己的项目会自动的跳转到cas的登陆页面，登陆完成后会跳转到自己项目的首页，注意主要是下面这句话的效果

shiroFilterFactoryBean.setLoginUrl("http://localhost:8080/cas/login?service=http://localhost:8000/shiro-cas");

首先登陆的请求被转发到

http://localhost:8080/cas/login
然后登陆成功会返回ticket，并重定向到

http://localhost:8000/shiro-cas

shiro-cas 会通过cas filter 拦截到shiro-cas，然后根据返回的username 对用户进行授权



还有一点需要注意的时候 ， cas 默认接受的参数名称是  username， password ，可以在cas.properties 中修改默认， 下面是我的登陆表单代码，仅供参考

<form action="/login/auth" method="post">
            <input id="username" type="text" name="username" class="username" placeholder="用户名">
            <input id="pwd" type="password" name="pwd" class="password" placeholder="密码">
            <button type="submit">登 录</button>
        </form>
