一、前言
在不同的项目中,可能由于业务需求或者架构方式的不同,对于用户登录的验证方式也不同。CAS为我们提供了很多的认证模式,其中最常见的认证方式有:
- JDBC认证,可以通过配置,也可以重写cas相关方法进行自定义认证
- LDAP认证
- Basic认证
- Shrio认证
- Pac4j认证
- MongoDB认证
- Rest认证
- IP黑白名单
- 第三方认证:微信,QQ,github等
在笔者最近接手的项目中,考虑后期验证方式的变化和程序的扩展性,决定重写CAS的验证方法进行自定义验证。另外,对于登录的验证信息,我们除了用户名和密码,可能还需要部门信息,验证码等等,这也需要重写cas的方法。

#ukey查询
user.ukey.query.sql = select u.USERID from USERINFO u left join ORGANINFO o on u.USERID=o.RID where u.UKEYSTRING = ?
#系统配置查询(通过系统配置服务获取自定义界面的一些配置信息的sql语句)
syscfg.query.sql = select SVALUE from SYSKEY where CCATALOG = ? and SKEY = ?
2.3 扩展登录信息
cas默认提供的登录信息往往不能满足我们的需求,在这里我们将增加系统名,验证码作为登录的扩展信息
继承RememberMeUsernamePasswordCredential
扩展登录信息
public class UsernamePasswordSubSystemCredential extends RememberMeUsernamePasswordCredential {
/**
* 验证码
*/
private String captcha;
/**
* 子系统
*/
private String system;
/**
* 获取验证码
*
* @return
* 验证码
*/
public String getCaptcha() {
return captcha;
}
/**
* 设置验证码
*
* @param captcha
* 验证码
*/
public void setCaptcha(String captcha) {
this.captcha = captcha;
}
/**
* 获取子系统
*
* @return
* 子系统
*/
public String getSystem() {
return system;
}
/**
* 设置子系统
*
* @param system
* 子系统
*/
public void setSystem(String system) {
this.system = system;
}
/**
* 计算hash码.
*
* 根据规范,一旦重写{@code equals()}就必须重写此{@code hashCode()}方法。
*/
@Override
public int hashCode() {
return new HashCodeBuilder().appendSuper(super.hashCode()).append(this.system).append(this.getCaptcha()).toHashCode();
}
}
将扩展的登录信息绑定到登录的webflow流程中
public class CustomWebflowConfigurer extends AbstractCasWebflowConfigurer {
/**
* 注入系统配置查询bean
*/
@Autowired
private SysConfigQueryService sysConfigQueryService;
/**
* 构造函数
*
* @param flowBuilderServices
* @param loginFlowDefinitionRegistry
*/
public CustomWebflowConfigurer(FlowBuilderServices flowBuilderServices, FlowDefinitionRegistry loginFlowDefinitionRegistry) {
super(flowBuilderServices, loginFlowDefinitionRegistry);
}
@Override
protected void doInitialize() throws Exception {
Flow flow = getLoginFlow();
bindCredential(flow);
}
/**
* 绑定输入信息
*
* @param flow
* 流程
*/
protected void bindCredential(Flow flow){
//重写绑定自定义credential
createFlowVariable(flow,CasWebflowConstants.VAR_ID_CREDENTIAL,UsernamePasswordSubSystemCredential.class);
//登录页绑定新参数
final ViewState state = (ViewState)flow.getState(CasWebflowConstants.STATE_ID_VIEW_LOGIN_FORM);
final BinderConfiguration cfg = getViewStateBinderConfiguration(state);
//由于用户名以及密码已经绑定,所以只需对新加系统参数绑定即可
//参数1 :字段名
//参数2 :转换器
//参数3 :是否必须的字段
cfg.addBinding(new BinderConfiguration.Binding("system", null, false));
cfg.addBinding(new BinderConfiguration.Binding("captcha",null,false));
//进入viewstate前传入参数(在系统参数绑定之后设置)
ActionList entryActionList = state.getEntryActionList();
entryActionList.add(createEvaluateAction("viewScope.newReg="+sysConfigQueryService.getNewRegister()));
entryActionList.add(createEvaluateAction("viewScope.pwdReset="+sysConfigQueryService.getResetPassword()));
entryActionList.add(createEvaluateAction("viewScope.codeValidate="+sysConfigQueryService.getImageValidate()));
//系统名称
entryActionList.add(createEvaluateAction("viewScope.sysTitle="+sysConfigQueryService.getSysTitle()));
}
}
在上面的代码中,我们除了绑定新添加的登录信息,还设置entryActionList(这个是Spring webflow的一个自定义切点,表示进入某个 state 之后,做其他事情之前,执行相关业务逻辑。Spring Web Flow 共定义了5个切入点,具体可以查看https://docs.spring.io/spring-webflow/docs/2.5.0.RELEASE/reference/html/el.html#el-variable-viewScope ),这样在页面上可以通过${newReg},${pwdReset}...
获取传入的相关信息来进行有一些逻辑操作。需要注意的是上面代码绑定新登录信息和设置entryActionList的顺序不能改变,否则在验证的时候无法获取新增的登录信息。另外,SysConfigQueryService
的代码也不贴出来了,这里主要就是通过jdbcTemplate查询系统配置信息。
注册修改后的登录流程
@Configuration("customerAuthWebflowConfiguration")
@EnableConfigurationProperties(value = CasConfigurationProperties.class)
@AutoConfigureBefore(value = CasWebflowContextConfiguration.class)
public class CustomerAuthWebflowConfiguration {
@Autowired
@Qualifier("logoutFlowRegistry")
private FlowDefinitionRegistry logoutFlowRegitry;
@Autowired
@Qualifier("loginFlowRegistry")
private FlowDefinitionRegistry loginFlowRegistry;
@Autowired
@Qualifier("builder")
private FlowBuilderServices builder;
@Bean
public CasWebflowConfigurer customWebflowConfigurer() {
final CustomWebflowConfigurer customWebflowConfigurer = new CustomWebflowConfigurer(builder, loginFlowRegistry);
customWebflowConfigurer.setLogoutFlowDefinitionRegistry(logoutFlowRegitry);
return customWebflowConfigurer;
}
}
2.4 自定义验证
这里我们使用jdbc进行验证,通过用户登录信息使用jdbcTemplate进行查询。
继承AbstractPreAndPostProcessingAuthenticationHandler
进行自定义认证
public class UsernamePasswordSystemAuthenticationHandler extends AbstractPreAndPostProcessingAuthenticationHandler {
/**
* 为了符合cacheService key的名称定义格式。
*/
public static final String CSUFFIX_USERLOGIN = "_2ae941e8-21e5-4013-9568-4dcee975333a";
/**
* 根据用户名和密码查询sql语句
*/
@Value("${user.password.query.sql}")
private String userQuerySql;
/**
* 根据ukey查询sql语句
*/
@Value("${user.ukey.query.sql}")
private String uKeyQuerySql;
/**
* jdbc模板
*/
@Autowired
private JdbcTemplate jdbcTemplate;
/**
* 构造函数
*
* @param name
* @param servicesManager
* @param principalFactory
* @param order
*/
public UsernamePasswordSystemAuthenticationHandler(String name, ServicesManager servicesManager, PrincipalFactory principalFactory, Integer order) {
super(name, servicesManager, principalFactory, order);
}
@Override
protected HandlerResult doAuthentication(Credential credential) throws GeneralSecurityException, PreventedException {
final UsernamePasswordSubSystemCredential upssc = (UsernamePasswordSubSystemCredential) credential;
final String username = upssc.getUsername();
//这里我省略了jdbc验证代码,大家可以自己去实现
if(username.equals("admin")){
return createHandlerResult(upssc, this.principalFactory.createPrincipal(upssc.getUsername(),Collections.emptyMap()), null);
}
return null;
}
@Override
public boolean supports(Credential credential) {
return credential instanceof UsernamePasswordSubSystemCredential;
}
}
注册自定义验证器
@Import({DataSourceAutoConfiguration.class})
@Configuration("customAuthenticationEventExecutionPlanConfiguration")
@EnableConfigurationProperties(CasConfigurationProperties.class)
public class CustomAuthenticationEventExecutionPlanConfiguration implements AuthenticationEventExecutionPlanConfigurer {
@Autowired
@Qualifier("servicesManager")
private ServicesManager servicesManager;
@Autowired
@Qualifier("jdbcPrincipalFactory")
public PrincipalFactory jdbcPrincipalFactory;
/**
* 注册验证器
*
* @return
*/
@Bean
public AuthenticationHandler customAuthenticationHandler() {
//优先验证
return new UsernamePasswordSystemAuthenticationHandler
("customAuthenticationHandler", servicesManager,new DefaultPrincipalFactory(),1);
}
//注册自定义认证器
@Override
public void configureAuthenticationExecutionPlan(final AuthenticationEventExecutionPlan plan) {
plan.registerAuthenticationHandler(customAuthenticationHandler());
}
}
我们在代码中增加了@Import({DataSourceAutoConfiguration.class})
,开启Spring Boot数据源自动配置,这样才可以使用使用jdbcTemplate。为什么在这里配置的,因为我会将个类配置在Spring Boot的自动配置扫描目录,当然你也可以配置在其它地方,保证其被扫描到就可以。
2.5 其它Bean配置
为了在自定义验证的类中注入其它bean执行验证逻辑,例如:注入缓冲bean,实现缓冲逻辑;注入系统配置bean,获取系统配置信息等,我们需要在这里式配置相关的bean,使其能被Spring Boot扫描到。
@Configuration
public class BeansConfiguration {
@Value("${syscfg.query.sql}")
private String syscfgQuerySql;
@Autowired
private JdbcTemplate jdbcTemplate;
@Bean
SysConfigQueryService sysConfigQueryService(){
return new SysConfigQueryService(syscfgQuerySql,jdbcTemplate);
}
@Bean
ICacheService cacheService(){
return new CacheService();
}
2.6 配置spring.factories
SpringFactoriesLoader属于Spring框架私有的一种扩展方案,其主要功能就是从指定的配置文件META-INF/spring.factories
加载配置。通过这个方法,我们就能将自定义的认证方法让spring boot 自动配置扫描到。
org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.simo.cas.config.CustomerAuthWebflowConfiguration,com.simon.cas.config.CustomAuthenticationEventExecutionPlanConfiguration,com.simon.cas.config.BeansConfiguration
