我有 Tomcat 9.0.12 和 Java JDK/JRE 1.8.0_191。我正在尝试配置 SSL/TLS。我已经像这样更改了我的 server.xml 文件：
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="443" />
<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="C:\my_certificate.pfx"
keystorePass="my_password" keystoreType="PKCS12" />
我的证书文件是 *.pfx 格式。我通过命令行使用 startup.bat 命令运行 tomcat 服务器。但是我收到了这样的错误（在我的 catalina.log 中）：
