cas单点注销失败Error Sending message to url endpoint

  最近在做cas单点登录时,由于是单点登录。必然会涉及到单点注销,然而在做单点注销时由于对cas注销机制不了解加之测试条件所致,所有测试都是在本机下完成(机器性能较低,没用虚拟机);导致折腾了很久。网上说的原因也各式各样,大部分原因集中在:

  1:你的CAS服务器将cookie设置成了浏览器有效,那么表示如果浏览器不关闭,则一直有效。
    在WEB-INF/spring-configuration/ticketGrantingTicketCookieGenerator.xml中设置cookie有效期,默认配置cookie有效期为-1

  2:你的应用中注销的filter-mapping没有放在所有mapping之前

  一一尝试过。无论怎么测试都出现了一个诡异的状况;本地测试可以正常退出,服务器端和客户端分离时则单点注销无法正常退出。官网的例子和说明也看了一遍又一遍,无论怎么尝试还是失败。直到操作了一下退出,然后服务器端看了下tomcat的日志,看到了一个WARN、Error日志。

2015-12-10 16:04:05,991 WARN [org.jasig.cas.util.SimpleHttpClient] - <Error Sending message to url endpoint [http://localhost:8080/usercenter//userdetails/add.html]. Error is [http://localhost:8080/usercenter//userdetails/add.html]>

  看到这有种蛋碎了一地的感觉,这是不是服务器端要和客户端通信,而服务端无法正常发送消息给客户端呢?于是

  原单点登录配置

  改完后,重启tomcat。再次测试,瞬间千万个草泥马呼啸而过。
