即使我已经获得了安全证书，但我仍收到SSL握手异常，并且还对Tomcat的server.xml文件进行了更改以支持TLSv1.2。连接数据库时，我收到此错误？任何帮助将不胜感激。
Java版本：1.7.0 Tomcat版本：7.0 .keystore
密钥位于默认文件夹C：/ user /...
server.xml
<Connector SSLEnabled="true" clientAuth="false" maxThreads="150" port="8443"
protocol="HTTP/1.1" scheme="https" secure="true" sslEnabledProtocols="TLSv1.2"/>
例外
