4、cas Server连接mysql

现在实现连接数据库 密码验证

新建一个web项目cass

将上节cas下的目录:

4、cas Server连接mysql_第1张图片

拷贝到项目的WebContent下,拷贝cas-server-support-jdbc-3.5.2.jar和mysql的驱动包到lib目录中;

如果用的eclipse就需要更改servers下的server.xml

这里将.keystore文件指定为绝对路径(\换为/):

               connectionTimeout="20000"
               redirectPort="8443" />

                 maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" keystoreFile="D:/Program Files (x86)/apache-tomcat8-bat/.keystore" keystorePass="111122"/>


查看web.xml文件,存在:


    contextConfigLocation
    
      /WEB-INF/spring-configuration/*.xml
      /WEB-INF/deployerConfigContext.xml
    
  

继续修改:deployerConfigContext.xml

注销:


这是验证用户名密码一致时的simple验证

添加的jdbc验证:


	 
	 
	 
	 
在下面添加datasource

	
	   com.mysql.jdbc.Driver
	   jdbc:mysql://localhost:3306/casserver
	   root
	   111122

		String ss = new MD5Code().getMD5ofStr(arg0);

我们需要预存个密码111122获取它的密文:

String ss = new MD5Code().getMD5ofStr("111122");
System.out.println(ss);

现在就去mysql创建数据库和表,将上步的密文复制到password上:

run as server  :http://localhost:8989/cass/login  出现正常的登陆界面,尝试用

https://localhost:8443/cass/login登陆,也出现正常的登陆界面,输入账号密码:

skx   111122

登陆成功。

需要下载 wsria-demo-sso-1.0.0.war的,点击我的链接,需要资源分5哦,主要是我最近没资源分了,给个支持哈:

可以查看下cookie:

用ie查看cookie

@配置一个单机登陆 Demo:

在eclipse的server下配置server.xml:

   
       

指向tomcat的一个页面:

重启tomcat:键入http://localhost:8989/examples/servlets/servlet/HelloWorldExample

4、cas Server连接mysql_第3张图片

参看wsria-demo-sso-1.0.0.war文件里的web.xml文件,没有下载就仿照以下配置文件:

1.修改host文件(C:\Windows\System32\drivers\etc):添加127.0.0.1   skx

1.将cas-client-core-3.2.1.jar和commons-logging-1.1.jar拷贝到D:\Program Files (x86)\apache-tomcat8-bat\webapps\examples\WEB-INF\lib中;

2.打开D:\Program Files (x86)\apache-tomcat8-bat\webapps\examples\WEB-INF目录,修改web.xml添加:


	
		CASFilter
		org.jasig.cas.client.authentication.AuthenticationFilter
		
			casServerLoginUrl
			https://skx:8443/gg/login
		
		
			serverName
			http://skx:8989
		
	
	 
		CASFilter 
		/* 
	 
  
  
		CAS Validation Filter
		
			org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter
		
			casServerUrlPrefix
			https://skx:8443/gg
		
		
			serverName
			http://skx:8989
		
	
	
		CAS Validation Filter
		/*
	
启动tomcat,键入:http://skx:8989/examples/servlets/servlet/HelloWorldExample你会发现自动跳转到cas登陆页面了

url也变成:https://skx:8443/gg/login?service=http%3A%2F%2Fskx%3A8989%2Fexamples%2Fservlets%2Fservlet%2FHelloWorldExample

这个service表示登陆成功后跳转的地址;

输入账号和密码  skx  111122 

出现:unable to find valid certification path to requested target

说明没有找到信任证书,可能是eclipse下的tomcat加载证书出现问题,这里不去修复了,有兴趣的朋友可以自行研究下

下节将介绍多系统之间的单点登陆,需要2台电脑,这才是我们想要的内容多节点单点登陆;安装好jdk和tomcat

本节内容就到此。
