最近在做CAS相关的内容，在搭建了CAS服务器之后，再搭建一个web client。可以通过简单的web项目搭建方法搭建。CAS 官方给出了较为详细的过滤器配置方法，甚至还给出了基于web.xml配置的示例。

Spring boot这么好用，不一起搞一下说不过去。那就搞一个。（这里暂时先只给出client端的配置）

1、首先是pom.xml。

<?xml version="1.0" encoding="UTF-8"?>

</project>

2、然后是application.propertites。配置自己客户端应用的地址和服务器的地址。

#tomcat started on port(s) : 8080 (http)
server.port=8080

#服务器的地址
cas.server-url-prefix=http://localhost:8900/cas
cas.server-login-url=http://localhost:8900/cas/login

#client 部署的地址
cas.client-host-url=http://localhost:8080
 
cas.validation-type=CAS

3、然后就是CasConfig.java ，这里是重要的地方：过滤器的配置，起的作用与在web.xml配置一样。

package com.xx.config;

import java.util.EventListener;
import java.util.HashMap;
import java.util.Map;

import org.jasig.cas.client.authentication.AuthenticationFilter;
import org.jasig.cas.client.session.SingleSignOutFilter;
import org.jasig.cas.client.session.SingleSignOutHttpSessionListener;
import org.jasig.cas.client.util.HttpServletRequestWrapperFilter;
import org.jasig.cas.client.validation.Cas30ProxyReceivingTicketValidationFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletListenerRegistrationBean;
import org.springframework.context.annotation.Bean;

/**
* @author Barry
* @date   2018年9月13日 下午3:47:18
*/
public class CasConfig {
	//url的前缀
    private static final String CAS_SERVER_URL_PREFIX = "http://localhost:8900";

    //本机的名称
    private static final String SERVER_NAME = "http://localhost:8080";
    
    /**
     * 登录过滤器
     * @return
     */
	@Bean
	public FilterRegistrationBean filterSingleRegistration() {
		FilterRegistrationBean registration = new FilterRegistrationBean();
		registration.setFilter(new SingleSignOutFilter());
		//设定匹配路径
		registration.addUrlPatterns("/*");
		Map<String,String> initParameters = new HashMap<String,String>();
		initParameters.put("casServerUrlPrefix",CAS_SERVER_URL_PREFIX);
		//设定加载顺序
		registration.setOrder(1);
		return registration;
	}
	
	/**
	 * 过滤验证器
	 * @return
	 */
	@Bean
	public FilterRegistrationBean filterValidationRegistration() {
		FilterRegistrationBean registration = new FilterRegistrationBean();
		registration.setFilter(new Cas30ProxyReceivingTicketValidationFilter());
		//设定匹配路径
		registration.addUrlPatterns("/*");
		Map<String,String> initParameters = new HashMap<String,String>();
		initParameters.put("casServerUrlPrefix", CAS_SERVER_URL_PREFIX);
		initParameters.put("serverName", SERVER_NAME);
		initParameters.put("useSession", "true");
		registration.setInitParameters(initParameters);
		//设定加载顺序
		registration.setOrder(1);
		return registration;
	}
	
	/**
	 * 	授权过滤器
	 * @return
	 */
	@Bean
	public FilterRegistrationBean filterAuthenticationRegistration() {
		FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new AuthenticationFilter());
        // 设定匹配的路径
        registration.addUrlPatterns("/*");
        Map<String,String>  initParameters = new HashMap<String, String>();
        initParameters.put("casServerLoginUrl", CAS_SERVER_URL_PREFIX);
        initParameters.put("serverName", SERVER_NAME);
        initParameters.put("ignorePattern", ".*");
        //表示过滤所有
        //initParameters.put("ignoreUrlPatternType", "com.yellowcong.cas.auth.SimpleUrlPatternMatcherStrategy");

        registration.setInitParameters(initParameters);
        // 设定加载的顺序
        registration.setOrder(1);
        return registration;
	}
	/**
     * wraper过滤器
     * @return
     */
    @Bean
    public FilterRegistrationBean filterWrapperRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new HttpServletRequestWrapperFilter());
        // 设定匹配的路径
        registration.addUrlPatterns("/*");
        // 设定加载的顺序
        registration.setOrder(1);
        return registration;
    }

    /**
     * 添加监听器
     * @return
     */
    @Bean  
    public ServletListenerRegistrationBean<EventListener> singleSignOutListenerRegistration(){  
        ServletListenerRegistrationBean<EventListener> registrationBean = new ServletListenerRegistrationBean<EventListener>();  
        registrationBean.setListener(new SingleSignOutHttpSessionListener());  
        registrationBean.setOrder(1);  
        return registrationBean;  
    }  


}

4、Springboot启动类中启用cas，类为：CasClientSbApplication.java

package com.xx;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.condition.ConditionalOnSingleCandidate;
import org.springframework.boot.context.logging.ClasspathLoggingApplicationListener;
import org.springframework.web.bind.annotation.GetMapping;

import net.unicon.cas.client.configuration.EnableCasClient;

@SpringBootApplication
@EnableCasClient
public class CasClientSbApplication {

	public static void main(String[] args) {
		SpringApplication.run(CasClientSbApplication.class, args);
	}
}

完了以后启动client端与server端，然后在浏览器输入http://localhost:8080/index.jsp，即会先跳转到如下页面
