六、cas 4.2.x 单点登出｜8月更文挑战

“这是我参与8月更文挑战的第10天，活动详情查看：8月更文挑战”

上一篇是cas配置shiro,这次说一说单点登出

cas配置shiro

依然给出官方文档,apereo.github.io/cas/4.2.x/i…

单点登出非常简单  在client web.xml中配置

<!-- 单点登出 -->
    <listener>
        <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>
    </listener>
    <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>

复制代码

这里也许会有人在项目启动时候报错:

java.lang.IllegalArgumentException: casServerUrlPrefix cannot be null.

原因也非常简单,jar包版本不对 解决方法:

​

在 cas server   中的 cas.properties中进行配置:

 # Specify whether CAS should redirect to the specified service parameter on /logout requests\
# cas.logout.followServiceRedirects=false
cas.logout.followServiceRedirects=true
复制代码

​

##
# Single Logout Out Callbacks
#
# To turn off all back channel SLO requests set this to true
# slo.callbacks.disabled=false

 slo.callbacks.disabled=false
复制代码

 ​

#
# To send callbacks to endpoints synchronously, set this to false
# slo.callbacks.asynchronous=true
slo.callbacks.asynchronous=true
复制代码

 ​

最后再说一种异常

web.xml 报错cvc-complex-type.2.4.a: Invalid content was found starting with element ‘cookie-config‘…

 导入cas源码 web.xml一直包红叉, 发现只要加了下面两句话 就ok了

     http://www.springmodules.org/schema/cache/springmodules-cache.xsd
    http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd
复制代码

原web.xml

<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

         version="3.0">
复制代码

修改后web.xml: 红色地方是修改地方,注意一定要包含在xmlns:xsi=” “之中.

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
         http://www.springmodules.org/schema/cache/springmodules-cache.xsd
         http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd
         "
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
