我正在尝试将 Spring Security SAML Extension 与 Spring Boot 集成。
关于此事,我确实开发了一个完整的示例应用程序。它的源代码可以在GitHub上找到:
通过将其作为Spring Boot应用程序运行(针对SDK内置的Application Server运行),WebApp可以正常工作。
不幸的是,相同的AuthN流程在 Undertow / WildFly 上根本不起作用。
根据日志,IdP实际执行 AuthN 过程:我的自定义UserDetails
实施的指令已正确执行。尽管有执行流程,但Spring并未设置并保留当前用户的权限。
@Component
public class SAMLUserDetailsServiceImpl implements SAMLUserDetailsService {
// Logger
private static final Logger LOG = LoggerFactory.getLogger(SAMLUserDetailsServiceImpl.class);
@Override
public Object loadUserBySAML(SAMLCredential credential)
throws UsernameNotFoundException, SSOUserAccountNotExistsException {
String userID = credential.getNameID().getValue();
if (userID.compareTo("jdoe@samplemail.com") != 0) { // We're simulating the data access.
LOG.warn("SSO User Account not found into the system");
throw new SSOUserAccountNotExistsException("SSO User Account not found into the system", userID);
}
LOG.info(userID + " is logged in");
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
GrantedAuthority authority = new SimpleGrantedAuthority("ROLE_USER");
authorities.add(authority);
ExtUser userDetails = new ExtUser(userID, "password", true, true, true,
true, authorities, "John", "Doe");
return userDetails;
}
}
调试时,我发现问题依赖于FilterChainProxy
类。在运行时,FILTER_APPLIED
的属性ServletRequest
具有 null 值,因此Spring会清除SecurityContextHolder
。
private final static String FILTER_APPLIED = FilterChainProxy.class.getName().concat(".APPLIED");
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
boolean clearContext = request.getAttribute(FILTER_APPLIED) == null;
if (clearContext) {
try {
request.setAttribute(FILTER_APPLIED, Boolean.TRUE);
doFilterInternal(request, response, chain);
} finally {
SecurityContextHolder.clearContext();
request.removeAttribute(FILTER_APPLIED);
}
} else {
doFilterInternal(request, response, chain);
}
}
在 VMware vFabric tc Sever 和 Tomcat 上,一切正常。你对解决这个问题有任何想法吗?
答案 0 :(得分:7)
调查问题我注意到在auth请求中有一些关于cookie和引用的混乱。
如果您将webapplication上下文更改为根上下文,则当前wildfly身份验证将起作用:
<server name="default-server" default-host="webapp">
<http-listener name="default" socket-binding="http"/>
<host name="default-host" alias="localhost" default-web-module="sso.war"/>
</server>
重新启动wildfly并清除cookie后,所有内容都应按预期工作
