rails 升级到2.2你可能会遇到的问题及解决方法
CAS 和Liferay的整合网上到处都有,我在此也不再鳌述。CAS和Alfresco的整合推荐一篇blog,你看了之后也就知道怎么做了:
http://athenalogics.blogspot.com/2008/07/how-to-casify-alfresco-cms_567.html
本文所要讲的是在CAS和Liferay已经整合好的前提下, 把Alfresco部署成Liferay的portlet并且和CAS整合。
我试了网上有一些别的方法无一成功,也有人说存在bug无法整合。至少根据我前面的blog讲share liferay session的方法给alfresco portlet是不可行的。alfresco的用户认证这里确实有bug。
当然,首先你需要把Alfresco部署成portlet,我这里用到的是Alfresco community version 2.1, Liferay 5.1.0
部署Liferay portlet 通常的做法是 Hotdeploy. 也就是把alfresco.war放到$user_home/liferay/deploy
之后会在Webapp下面产生一个新的alfresco的app, 到它的lib下面把portlet-api删掉,因为这个和liferay的相冲突。然再把附件中的liferay portlet描述文件copy到alfresco/WEB-INF下面. 注意,附件里的web.xml中用到的portlet-class是我自己修改过的。
这样你的alfresco就可以被添加到liferay里面了.
当然,如果你不想使用hotdeploy(通常写自动产生server的script的人最讨厌这个), 那么可以参考这个script的相应部分: http://tempo.intalio.org/tempo/trunk/rsc/scripts/create_tomcat.rb
接下来,Alfresco portlet的用户管理的基本思路是在PortletSession里是否存在'AuthenticationHelper.AUTHENTICATION_USER'这个属性,如果存在的话就取出里面的User去做验证。通过的话就可以访问。基于这个原理,我在原有的portlet-class上做了一些改动,下面的portlet class的全文:
从上面的代码可以看出,拿去认证的用户是从Liferay的Session里拿到的当前登陆的用户,我们认为这个用户如果在alfresco里存在的话,那么也是可以访问alfresco的。这里我并没有完全整合用户认证,而是做了一个各个系统之间用户的对应关系。比如CAS的用户名和Liferay的Screen Name必须是一样的。那么从上面的代码中我们可以看到Liferay的用户的First Name必须和Alfresco的用户名一样。
更完善的三者整合是在这里: http://liferay.cignex.com/ 当然他们的方法就是中央管理了用户(LDAP)而不需要user mapping了
接下来,你只要在你的mysql里面创建一个名为alfresco的数据库,然后创建相应的用户。再start server就好了。
所有的portlet描述文件和这个portlet-class都在附件的包里. enjoy~

从上面的代码可以看出,拿去认证的用户是从Liferay的Session里拿到的当前登陆的用户,我们认为这个用户如果在alfresco里存在的话,那么也是可以访问alfresco的。这里我并没有完全整合用户认证,而是做了一个各个系统之间用户的对应关系。比如CAS的用户名和Liferay的Screen Name必须是一样的。那么从上面的代码中我们可以看到Liferay的用户的First Name必须和Alfresco的用户名一样。
更完善的三者整合是在这里: http://liferay.cignex.com/ 当然他们的方法就是中央管理了用户(LDAP)而不需要user mapping了
接下来,你只要在你的mysql里面创建一个名为alfresco的数据库,然后创建相应的用户。再start server就好了。
create database alfresco; grant all on alfresco.* to 'alfresco'@'localhost' identified by 'alfresco' with grant option; grant all on alfresco.* to 'alfresco'@'localhost.localdomain' identified by 'alfresco' with grant option;
所有的portlet描述文件和这个portlet-class都在附件的包里. enjoy~
