服务器的握手错误与客户端验证服务器证书无关。因此，信任新证书无助于解决此错误。
*** ClientHello, TLSv1
尽管服务器根据 SSLLabs 只能执行 TLS 1.2，但您的客户端仅发送 TLS 1.0 请求。
在这种情况下，您已经为 tomcat server 配置了 TLS 1.2 并不重要，因为问题在于您的 TLS client无法连接到第三方服务器。有关如何配置 Java 7 以在客户端使用 TLS 1.2 的示例，请参阅 Enabled TLS 1.2 and TLS 1.1 on Java 7。
我在 linux 服务器上使用 Tomcat 7.065 和 APR 1.1.33 Java 1.7.0_67.
我的应用程序多年来一直通过 SSL 愉快地连接到第 3 方站点。第 3 方颁发了新证书。第三部分网站是： https://its.changehealthcare.com/
我下载了 .cer 文件并进行了密钥工具导入：
$JAVA_HOME/bin/keytool -import -trustcacerts -keystore cacerts -noprompt -file path\to\certificate.cer

I downloaded the .cer file and did a keytool import ... But I continue to get an ssl handshake error.
服务器的握手错误与客户端验证服务器证书无关。因此，信任新证书无助于解决此错误。
*** ClientHello, TLSv1
尽管服务器根据 SSLLabs 只能执行 TLS 1.2，但您的客户端仅发送 TLS 1.0 请求。
在这种情况下，您已经为 tomcat server 配置了 TLS 1.2 并不重要，因为问题在于您的 TLS client无法连接到第三方服务器。有关如何配置 Java 7 以在客户端使用 TLS 1.2 的示例，请参阅 Enabled TLS 1.2 and TLS 1.1 on Java 7。
