我正在努力将Apache NiFi的OkHttp版本从2.5更新到2.6。这样做时，所有HTTPS测试都会因此异常而失败：
javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
测试使用Jetty服务器周围的包装器作为它连接的主机。信任库和密钥库对于主机和客户端是相同的。由于某种原因，从2.5到2.6的变化导致服务器提前关闭。
我唯一改变的是Maven中的OkHttp版本，从2.5到2.6。测试类在这里（实现在TestInvokeHttpCommon中）： https://github.com/apache/nifi/blob/8c2323dc8d0e107f1a99898370c7515fa9603122/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/test/java/org/apache/nifi/processors/standard/TestInvokeHttpSSL.java

问题确实是一个特定的密码套件ConnectionSpec从新版本的OkHttp中被淘汰。要解决此问题，代码可用于提供@JesseWilson建议的自定义ConnectionSpec.Builder obsoleteSpecBuilder = new ConnectionSpec.Builder(ConnectionSpec.COMPATIBLE_TLS);
obsoleteSpecBuilder = obsoleteSpecBuilder.cipherSuites("TLS_DHE_DSS_WITH_AES_128_CBC_SHA");
ConnectionSpec obsoleteSpec = obsoleteSpecBuilder.build();
okHttpClient.setConnectionSpecs(Arrays.asList(obsoleteSpec));
实例。
TLS_*DSS*然而，根本问题是Jetty使用的密钥库和信任库没有任何有效的RSA或DSA密钥（有一个DSA密钥但它在2年前过期。显然日期检查在以前的测试中没有激活） 。如果没有这些密钥，Jetty将无法提供任何依赖于RSA / DSA的密码套件，因此一旦删除了hw12203:...src/test/resources alopresto

密码套件，客户端就没有兼容的密码套件。
将RSA密钥添加到密钥库和信任库可以解决此问题，而无需依赖旧密码套件。
