最近，在做CAS单点登陆的一个模块，由于公司的产品太多，各个系统都要部署，在开发中Https的证书的部署比较麻烦，所以，打算把CAS的Https去掉。具体的修改如下

1.修改cas-servlet.xml

<bean id="warnCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
p:cookieSecure="true"
p:cookieMaxAge="-1"
p:cookieName="CASPRIVACY"
p:cookiePath="/cas" />
<bean id="ticketGrantingTicketCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
p:cookieSecure="true "
p:cookieMaxAge="-1"
p:cookieName="CASTGC"
p:cookiePath="/cas" />

把上面连个bean中的p:cookieSecure="true "修改为p:cookieSecure="false"
2.修改deployerConfigContext.xml

<bean class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"
p:httpClient-ref="httpClient" />

添加p:requireSecure="false"

3.修改casclient的客户端

修改客户端的https验证
(1).edu.yale.its.tp.cas.client.filter.edu.yale.its.tp.cas.client.filter

if (! casValidate.startsWith("https://")){
throw new ServletException("validateUrl must start with https://, its current value is [" + casValidate + "]");
}
if (casServiceUrl != null){
if (! (casServiceUrl.startsWith("https://")|| (casServiceUrl.startsWith("http://") ))){
throw new ServletException("service URL must start with http:// or https://; its current value is [" + casServiceUrl + "]");
}
}

把这两段内容注释掉

(2).修改edu.yale.its.tp.cas.util.SecureURL

if (!u.getProtocol().equals("https")){
// IOException may not be the best exception we could throw here
// since the problem is with the URL argument we were passed, not
// IO. -awp9
log.error("retrieve(" + url + ") on an illegal URL since protocol was not https.");
throw new IOException("only 'https' URLs are valid for this method");
}

把这段内容注释掉
