Tomcat支持https

1、上阿里云购买证书，有免费版证书。
2、修改/user/share/tomcat9/conf/server.xml
    <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true">
        <SSLHostConfig>
            <Certificate certificateKeystoreFile="/xx/xxxxxx.pfx"
                         certificateKeystorePassword="xxxxxx" certificateKeystoreType="PKCS12"  />
        </SSLHostConfig>
    </Connector>

3、支持多地址多证书
  <Service name="Catalina">
    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="443" URIEncoding="UTF-8" />
    <Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true" defaultSSLHostConfigName="localhost" >
        <SSLHostConfig hostName="xxx.xxx.cn" >
            <Certificate certificateKeystoreFile="/www/cert20201126/xxx.xxx.cn.pfx"
                         certificateKeystorePassword="xxx" certificateKeystoreType="PKCS12"  />
        </SSLHostConfig>
        <SSLHostConfig hostName="localhost" >
            <Certificate certificateKeystoreFile="/www/cert20201123/xxx.cn.pfx"
                         certificateKeystorePassword="xxx" certificateKeystoreType="PKCS12"  />
        </SSLHostConfig>
    </Connector>
    <Connector port="8009" protocol="AJP/1.3" redirectPort="443" />
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
      <Host name="xxx.xxx.cn"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
      <Host name="localhost" appBase="www" unpackWARs="true" autoDeploy="true">
        <Alias>www.xxx.cn</Alias>
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
        <Context path="" docBase="/data/html" reloadable="true" crossContext="true"></Context>
      </Host>
    </Engine>
  </Service>
