classnotfoundexception - javax.net.ssl.SSLException : Server selected improper ciphersuite SSL_RSA_WITH_DES_CBC_SHA

Question

当通过 HTTPS 连接提供小程序时，我收到以下异常。

此问题在 Java 1.7.0_25 中出现，但在 java 1.6 中没有出现。

当我查看java支持的chipersuit(http://docs.oracle.com/javase/1.5.0/docs/guide/security/jsse/JSSERefGuide.html#PLUG)时，我在列表中看到SSL_RSA_WITH_DES_CBC_SHA。

有人遇到过这个错误吗？我应该怎么处理这个错误？

该问题很可能与反向代理设置有关。例如，在 apache 中，您必须设置以下参数。

ProxyPass /foo http://foo.example.com/bar
ProxyPassReverse /foo http://foo.example.com/bar

您可以为其他反向代理服务器找到类似的选项。
