上篇博客介绍的CAS的Demo,登录界面用户名、密码并没有通过数据库查询认证。本博客,将介绍如何通过xml配置,进行CAS登录数据库查询认证。
所需数据库sso_cas,库中的表:tb_user,表中字段:Id、username、password;
数据库查询认证(通过xml配置)
1,修改cas服务端配置
tomcat下webapps/cas/WEB_INF/deployerConfigContext.xml 文件做如下修改:
修改为:
添加datasource bean的定义:
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
注意
1,QueryDatabaseAuthenticationHandler是cas-server-support-jdbc提供的查询接口其中一个是通过配置一个 SQL 语句查出密码,与所给密码匹配;
2,sql语句:select password from tb_user whereusername=?根据用户名username 查询表tb_user中密码password字段,CAS会匹配用户输入的密码,如果匹配则通过;
注:可配置多个数据库
如果需要配置多个数据库,可以配置多个QueryDatabaseAuthenticationHandler和多个datasource
假如a_user中有一个用户:auser,b_user中有一个用户buser,这样你无论用哪一个用户登录,CAS就会先查a_user,如果用户名密码都正确,那么就通过,如果a_user中验证失败,那么CAS就会再查b_user,用户名密码都正确就算通过了,此时不正确,就算这次登录验证没通过。
添加相关的jar包
需要在web项目的lib下添加两个包:cas-server-support-jdbc-x.x.x.jar 和 mysql-connector-java-x.x.x-bin.jar(具体版本号根据情况而定)
按如下配置好后,进入CAS登录页,用户名密码需要通过查询数据库来认证,输入用户名admin,密码123,才可登录成功;如果输入用户名admin,密码admin是不能登录成功。
