我已经在我的应用程序中配置了 spring-saml 和 spring security。我给出了不同的 url 模式来识别请求。如果我附加 /休息在应用程序 URL 中，它将创建具有基本身份验证的 spring-security 上下文。如果我附加 /saml 在应用程序 URL 中，它会在成功登录后填充 IDP 登录页面并重定向到 index.html。
但是我再次被重定向到 login.html 页面而不是 index.html。在 Eclipse 调试并在这里和那里放置一些日志之后，我发现没有可用的身份验证对象。
我读过这篇 jira link并将 spring-security 版本更新为 3.1.4.RELEASE 但它没有解决我的问题。
经过一番努力后，我发现通过 filterChainProxy doFilter 方法清除了 saml 安全上下文，并将身份验证设置为 null，然后重定向到需要身份验证的安全目标 url，但该 URL 不存在。因此它重定向到登录页面。
我用谷歌搜索了很多，但没有找到任何使用 saml 身份验证通过 j_spring_security 检查的方法。
我在下面附上了我的 saml-security.xml 和 spring-security.xml 文件

谁能帮我解决这个问题。
提前致谢。
最佳答案
经过近一个星期的挣扎，我终于解决了这个问题。
在通过 Eclipse 进行调试时，我发现 SAMLAuthenticationProvider 中的根本原因有一个方法 getEntitlements这导致了问题。
protected Collection<? extends GrantedAuthority> getEntitlements(SAMLCredential credential, Object userDetail) {
if (userDetail instanceof UserDetails) {
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.addAll(((UserDetails) userDetail).getAuthorities());
return authorities;
} else {
return Collections.emptyList();
}
}
这里检查 userDetail 对象是否是一个 instanceOf UserDetails 类，然后返回所有权限列表，否则将返回空的权限列表。
返回
UserDetails 的基于表单的身份验证很好对象，但如果用户通过 IDP 登录发起 SSO，则对象类型为 UsernamePasswordAuthenticationToken将返回。因此，它使用 userDetail 对象获取了 grantAuthourity 的空列表。所以我扩展了
SAMLAuthenticationProvider在我的应用程序中并覆盖以下方法@Override
public Collection<? extends GrantedAuthority> getEntitlements(SAMLCredential credential, Object userDetail)
{
logger.info("****** object is instance of UserDetails :"+ (userDetail instanceof UserDetails));
if (userDetail instanceof UserDetails)
{
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.addAll(((UserDetails) userDetail).getAuthorities());
return authorities;
}
else if(userDetail instanceof UsernamePasswordAuthenticationToken)
{
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.addAll(((UsernamePasswordAuthenticationToken) userDetail).getAuthorities());
return authorities;
} else {
return Collections.emptyList();
}
}
然后我将我的自定义 authenticationProvider 引用提供到 saml-security.xml 文件中，并使用我的自定义 SAMLUserDetailsService 类引用。
<bean id="samlAuthenticationProvider" class="com.mercatus.security.MercatusSAMLAuthenticationProvider">
<property name="userDetails" ref="samlUserDetailsService" />
</bean>
<bean id="samlUserDetailsService" class="com.mercatus.security.MercatusSAMLUserDetailsService"/>
上面的配置救了我。登录后我可以访问 protected 资源。
我花了整整一周的时间在 FilterChainProxy 和许多其他过滤器中调试，因为拦截器 URL 重定向到 FilterChainProxy。
我发布详细信息是因为它可能对面临类似问题的其他人有所帮助。
关于spring - 即使在 IDP 使用 SAML 成功登录后，获取身份验证对象也为空，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29300048/
