Failed to initialize connector

问题:

SEVERE: Failed to initialize component [Connector[org.apache.coyote.http11.Http11AprProtocol-8443]] org.apache.catalina.LifecycleException: The configured protocol [org.apache.coyote.http11.Http11AprProtocol] requires the APR/native library which is not available.

I have commented the connector for http and opened the connector for http2.

here is the code :

 <Connector port="9000" protocol="org.apache.coyote.http11.Http11AprProtocol"
                   maxThreads="150" SSLEnabled="true" >
            <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
            <SSLHostConfig>
                <Certificate certificateKeyFile="conf/localhost-rsa-key.pem"
                             certificateFile="conf/localhost-rsa-cert.pem"                         
                             type="RSA" />
            </SSLHostConfig>
        </Connector>

I am getting an error while starting the server.
