java - 不偶尔发送证书

Question

在我的应用程序中，我有 2 个组件通过 REST(基于客户端-服务器)相互通信。
该应用程序可以配置为使用 HTTP 或 HTTPS(自签名证书)。

有时，当我在 HTTPS 模式下启动我的应用程序时，我的客户端无法与服务器通信。我收到以下异常:

    09-16-2013 12:28:52 [dispatcher] [http-nio-8143-exec-8] [INFO] - Exception while dispatching request
java.util.concurrent.ExecutionException: com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
    ...
Caused by: com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
    ...
Caused by: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
    ...
Caused by: java.io.EOFException: SSL peer shut down incorrectly
    ...

当我停止并启动应用程序时，一切都按预期工作。
我尝试搜索解决方案，但时不时发生并通过重启修复的问题找不到与我的问题相似的任何问题，所有问题都是一致的。

Java 版本:Oracle Corporation，“Java HotSpot(TM) 64 位服务器虚拟机”，1.7.0_17-b02 操作系统:红帽 有什么想法吗？

更新
事实证明，这也可能在应用程序运行一段时间后发生。意思是，一切正常，SSL 通信正常，突然出现此错误，并且在我重新启动客户端之前不会解决。

我能够通过 -Djavax.net.debug=all 重现该问题，显然客户端未发送证书，问题是为什么。有时一切都很顺利，但有时会出现问题的原因是什么？

Answer 1

javax.net.ssl.SSLHandshakeException: null cert chain

看起来服务器需要客户端证书，而您没有发送证书，或者发送的内容无效。您将在客户端 SSL 日志的更上方有一个入站 CertificateRequest，它后面没有出站 Certificate 消息，或者后面跟着一个空消息。
