conf/server.xml添加：

<Connector port="443" protocol="org.apache.coyote.http11.Http11Nio2Protocol" defaultSSLHostConfigName="ssl.****.cn" 
               maxThreads="350" SSLEnabled="true" >
        <SSLHostConfig hostName="ssl.****.cn">
            <Certificate certificateKeystoreFile="D:/Env/Tomcat85/https/domain1.jks" certificateKeystorePassword="v*****m" type="RSA" />
        </SSLHostConfig>
          <SSLHostConfig hostName="ssl.****.com">
              <Certificate certificateKeystoreFile="D:/Env/Tomcat85/https/domain2.jks" certificateKeystorePassword="2*****a" type="RSA" />
          </SSLHostConfig>
</Connector>

SSLHostConfig可以添加多个，就是多个ssl证书。tomcat8.5以上支持。
