Facing compilation errors due to deletion of methods in class AbstractHttp11Protocol (Tomcat 10.x)

Question

We are using the below setter methods of class AbstractHttp11Protocol to configure mTLS in spring-boot based application. After upgrading the application to spring-boot 3, started facing some issues related to Tomcat. I am facing compilation errors and got to know that these methods have been removed in Tomcat 10.x version.

    @Bean
    public WebServerFactoryCustomizer<TomcatServletWebServerFactory> containerCustomizer() {

        return configurableEmbeddedServletContainer -> {
            if (configurableEmbeddedServletContainer != null) {
                TomcatServletWebServerFactory tomcatEmbeddedServletContainerFactory = configurableEmbeddedServletContainer;
                tomcatEmbeddedServletContainerFactory.addAdditionalTomcatConnectors(additionalConnector(serverConfig()));
            }
        };
    }

    private Connector additionalConnector(ServerConfig serverConfig) {

        SslConfig sslConfig = serverConfig.getSsl();

        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
        connector.setScheme(SCHEME);
        connector.setSecure(true);
        connector.setPort(serverConfig.getPort());
        protocol.setSSLEnabled(true);

        //getting complilation errors in below code
        protocol.setKeystoreType(sslConfig.getKeyStoreType());
        protocol.setKeystoreFile(sslConfig.getKeyStore());
        protocol.setKeystorePass(String.valueOf(sslConfig.getKeyStorePassword()));
        protocol.setKeyPass(String.valueOf(sslConfig.getKeyPassword()));
        protocol.setTruststoreType(sslConfig.getTrustStoreType());
        protocol.setTruststoreFile(sslConfig.getTrustStore());
        protocol.setTruststorePass(String.valueOf(sslConfig.getTrustStorePW()));
        protocol.setSSLProtocol(TLSV_1_2);
        protocol.setClientAuth("true"); 

        return connector;
    }

Find below commit where changes have been made in AbstractHttp11Protocol class for Tomcat 10.x :-

Remove support for deprecated TLS configuration style

Please suggest if there is any alternative approach to configure these properties or how to use these methods in Tomcat 10.x.

You need to show the error message! I presume you realise Tomcat 10 is Jakarta project and uses the Jakarta package name for any framework API not javax unless the javax class is from SE core. — Samuel Marchant, Jul 12 '23 at 04:09
@SamuelMarchant, the application is not giving error of Jakarta package name change as I am already using the latest dependencies and also have made changes related to this. I have edited the question, you can find the error in the question. — Jagdish Raika, Jul 12 '23 at 06:30
At a quick glance I don't see anything here that you couldn't control via `server.xml`. Why are you writing code for this? — user207421, Jul 12 '23 at 10:01
