自定义验证很重要,因为我们后续的很多功能,都是基于自定义验证。  
CAS服务器的org.apereo.cas.authentication.AuthenticationManager负责基于提供的凭证信息进行用户认证。与Spring Security很相似，实际的认证委托给了一个或多个实现了org.apereo.cas.authentication.AuthenticationHandler接口的处理类。在cas的认证过程中逐个执行authenticationHandlers中配置的认证管理，直到有一个成功为止。  
CAS内置了一些AuthenticationHandler实现类，如下图所示，QueryDatabaseAuthenticationHandler中提供了基于jdbc的用户认

如果需要实现自定义登录，只需要实现org.apereo.cas.authentication.AuthenticationHandler接口即可。当然也可以利用已有的实现，比如创建一个继承自org.apereo.cas.authentication.handler.support.AbstractPreAndPostProcessingAuthenticationHandler的类。下面我们就来实现自定义验证。

**自定义登入**

pom.xml 添加如下依赖jar包

<dependency>
    					<groupId>org.apereo.cas</groupId>
    					<artifactId>cas-server-core-webflow</artifactId>
    					<version>${cas.version}</version>
    				</dependency>
    				
    				<dependency>
    					<groupId>org.apereo.cas</groupId>
    					<artifactId>cas-server-core-authentication</artifactId>
    					<version>${cas.version}</version>
    				</dependency>
    				<dependency>
    					<groupId>org.apereo.cas</groupId>
    					<artifactId>cas-server-core-authentication-api</artifactId>
    					<version>${cas.version}</version>
    				</dependency>
    				<dependency>
    					<groupId>org.apereo.cas</groupId>
    					<artifactId>cas-server-core-webflow-api</artifactId>
    					<version>${cas.version}</version>
    				</dependency>

自定义验证类,继承AbstractPreAndPostProcessingAuthenticationHandler

**绑定自定义认证流程和自定义凭证信息**

package com.digipower.captcha.config;

**创建用户登入凭证，添加验证码属性**

                    .toHashCode();
        }
    
    
    }

**重新定义Apereo Cas5 服务端的登入流程**

package com.digipower.webflow.action;
    
    import org.apereo.cas.configuration.CasConfigurationProperties;
    import org.apereo.cas.web.flow.CasWebflowConstants;
    import org.apereo.cas.web.flow.configurer.DefaultLoginWebflowConfigurer;

    /**

     * @author zzg
     *
     */
    public class CaptchaWebflowConfigurer extends DefaultLoginWebflowConfigurer {
    
    
    	
    	public CaptchaWebflowConfigurer(FlowBuilderServices flowBuilderServices,
    			FlowDefinitionRegistry flowDefinitionRegistry, ApplicationContext applicationContext,
    			CasConfigurationProperties casProperties) {
    		super(flowBuilderServices, flowDefinitionRegistry, applicationContext, casProperties);
    	}
    
    	@Override
    	protected void createRememberMeAuthnWebflowConfig(Flow flow) {
    		 if (casProperties.getTicket().getTgt().getRememberMe().isEnabled()) {

    	            final ViewState state = getState(flow, CasWebflowConstants.STATE_ID_VIEW_LOGIN_FORM, ViewState.class);
    	            final BinderConfiguration cfg = getViewStateBinderConfiguration(state);
    	            cfg.addBinding(new BinderConfiguration.Binding("rememberMe", null, false));
    	            cfg.addBinding(new BinderConfiguration.Binding("captcha", null, true));
    	        } else {

    	        }
    	}
    
    }

**修改Apereo Cas 5 系统自带的登入流程定义webflow**

在login-webflow.xml/viewLoginForm 添加如下代码：

源码修改如下：

<?xml version="1.0" encoding="UTF-8"?>
    <flow xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns="http://www.springframework.org/schema/webflow"

                              http://www.springframework.org/schema/webflow/spring-webflow.xsd">
    
        <action-state id="initializeLoginForm">
            <evaluate expression="initializeLoginAction" />
            <transition on="success" to="viewLoginForm"/>
        </action-state>
    
        <view-state id="viewLoginForm" view="casLoginView" model="credential">

        </view-state>

            <transition on="error" to="initializeLoginForm"/>
        </action-state>
    
    </flow>

**将自定义登入流程添加如Apereo Cas 5服务器中webflow 中**

    import org.springframework.webflow.engine.builder.support.FlowBuilderServices;
    import com.digipower.webflow.action.CaptchaWebflowConfigurer;
    
    /**

    @Configuration("captchaWebflowConfigurer")
    @EnableConfigurationProperties(CasConfigurationProperties.class)
    @AutoConfigureBefore(value = CasWebflowContextConfiguration.class)

    	private FlowBuilderServices flowBuilderServices;
    
    	@Bean("defaultLoginWebflowConfigurer")
    	public CasWebflowConfigurer defaultLoginWebflowConfigurer() {
    		CasWebflowConfigurer c = new CaptchaWebflowConfigurer(flowBuilderServices, loginFlowRegistry,
    				applicationContext, casProperties);
    		c.initialize();
    		return c;
    	}
    }

补充相关的工具类：Kaptcha 图形验证码初始化，用户密码加密工具类，springBean 工具类和相关自定义异常

加载该配置类

在resources\\META-INF\\spring.factories中配置该类

org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.digipower.captcha.config.CaptchaConfigurer,\

    	com.digipower.captcha.config.UsernamePasswordCaptchaConfig,\
    	com.digipower.util.SpringContextUtils

系统登入页面修改，添加验证码（/templates/fragments/loginfrom.html）,添加如下代码：

<section class="form-group">
                                <label for="captcha">验证码</label>
    
                                <div>
