Spring Security 3 证书登录
默认情况下ss3的<x509>标签只会取证书主题作为验证条件，如果想要自己指定证书的某一部分作为验证条件需要手动实现X509PrincipalExtractor接口：
import org.springframework.security.web.authentication.preauth.x509.X509PrincipalExtractor;public class MyX509PrincipalExtractor implements X509PrincipalExtractor{Logger logger = LoggerFactory.getLogger(this.getClass());/** * 获取证书序列号 * @param cert x509证书对象 */@Overridepublic Object extractPrincipal(X509Certificate cert) {String serialNumber = cert.getSerialNumber().toString(16);//取证书序列号作为判断条件return serialNumber;}}?实现用户描述接口：
public class MyUserAuthority implements UserDetails{……}?
载入用户信息：
import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.security.core.Authentication;import org.springframework.security.core.userdetails.AuthenticationUserDetailsService;import org.springframework.security.core.userdetails.UserDetails;import org.springframework.security.core.userdetails.UsernameNotFoundException;/** * * Company: xxx公司 <br> * * Description: 用户信息载入服务 * * <br>Copyright: Copyright (c) 2010 - 2015 * * <br>Author: JLCON * <br>Created:2010-9-17 * * <br>Modified:2010-9-17 * * <br>version：V1.0 */public class MyUserDetailService implements AuthenticationUserDetailsService{Logger logger = LoggerFactory.getLogger(this.getClass()); //载入用户信息@Autowiredprivate UserAuthorityInfo userinfo;/** * 用户信息载入 * @param token 认证token */@Overridepublic UserDetails loadUserDetails(Authentication token)throws UsernameNotFoundException {//这里得到的就是刚才返回的证书IDreturn userinfo.getUserDetails(token.getPrincipal().toString());}}?通过URL获取该URL具有的访问属性：
public class X509securityMetadataSource implements FilterInvocationSecurityMetadataSource{import org.springframework.security.web.access.intercept.FilterInvocationSecurityMetadataSource;…………@Overridepublic Collection<ConfigAttribute> getAttributes(Object object)throws IllegalArgumentException {String url = ((FilterInvocation)object).getRequestUrl();………………return list;}@Overridepublic boolean supports(Class<?> clazz) {return true;}}?认证访问控制器：
public class X509AccessDecisionManager implements AccessDecisionManager{Logger logger = LoggerFactory.getLogger(this.getClass());/** * 决定是否有权限访问资源 * @param authentication 登录用户权限信息 * @param object 访问的资源对象 * @param configAttributes 资源对象具有的配置属性 * @exception AccessDeniedException 访问被拒绝 */@Overridepublic void decide(Authentication authentication, Object object,Collection<ConfigAttribute> configAttributes)throws AccessDeniedException, InsufficientAuthenticationException {FilterInvocation filterInvocation = (FilterInvocation)object;for(ConfigAttribute configAttribute:configAttributes){for(GrantedAuthority grantedAuthority:authentication.getAuthorities()){if(configAttribute.getAttribute().equalsIgnoreCase(grantedAuthority.getAuthority())){logger.debug("访问success! - {}",filterInvocation.getFullRequestUrl());return;}}}logger.debug("无权访问! - {}",filterInvocation.getFullRequestUrl());throw new AccessDeniedException("无权限！");}@Overridepublic boolean supports(ConfigAttribute attribute) {return true;}@Overridepublic boolean supports(Class<?> clazz) {return true;}}??最后上配置：
