如何将证书放入X509过滤器（Spring Security）？

我需要提取更多的信息，而不仅仅是证书的CN。目前，我只获得标准的UserDetails loadUserByUsername（String arg），其中arg是证书的CN。我需要获取X509Certificate对象。可能吗？如何将证书放入X509过滤器（Spring Security）？

春安全XML文件：

<x509 subject-principal-regex="CN=(.*?)," user-service-ref="myUserDetailsService" />

不，你不能得到它的方式。您需要将来自HttpServletRequest抓住它：

X509Certificate[] certs = (X509Certificate[])HttpServletRequest.getAttribute("javax.servlet.request.X509Certificate");

如果你打印出'cert [0] .toString（）'，那么证书应该以'---- BEGIN CERTIFICATE ---- ....'开头，最后是---- ---- END CERTIFICATE -----'？ – 2013-05-09 18:46:28

还值得一提的是，一旦你被授权内置的Spring SecurityX509AuthenticationFilter，因为它已经接受了你的证书，那么你就可以访问X509Certificate为

Object object = SecurityContextHolder.getContext().getAuthentication().getCredentials(); 
if (object instanceof X509Certificate) 
{ 
    X509Certificate x509Certificate = (X509Certificate) object; 
    //convert to bouncycastle if you want 
    X509CertificateHolder x509CertificateHolder = 
     new X509CertificateHolder(x509Certificate.getEncoded()); 
    ...
