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）相互通信可以将应用程序配置为使用HTTP或HTTPS（自签名证书）。

有时我在HTTPS模式下启动应用程序时，我的客户端无法与服务器通信。我遇到以下异常：

    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试着寻找解决方案，但找不到任何类似于我的问题的东西，不时发生并通过重新启动修复，所有问题都是一致的。

Java版：Oracle Corporation，'Java HotSpot（TM）64位服务器VM'，1.7.0_17-b02 操作系统：红帽有什么想法吗？

更新
事实证明，在应用程序运行一段时间后也会发生这种情况。意思是，一切正常，SSL通信正常，突然发生此错误，直到我重新启动客户端才会解决。

我能够用-Djavax.net.debug = all重现问题，显然证书不是从客户端发送的，问题是为什么。有时候一切顺利，有什么可能导致事情不时出错？

Answer 1

javax.net.ssl.SSLHandshakeException: null cert chain

看起来服务器需要客户端证书，而您没有发送一个或发送无效的内容。您将在客户端SSL日志中进一步向上CertificateRequest，而不是出站Certificate消息，或者后面是空消息。

Answer 2

显然有人添加了代码来覆盖证书：

        HttpsURLConnection.setDefaultSSLSocketFactory(ctx.getSocketFactory());

我删除了这一行，现在一切正常。

证书没有偶尔发送
