Spring boot mongo tls cert

I have set up TLS in mongod.conf. I need to use spring boot to connect to my mongo which requires tls now. In MongoCompass, I set Certificate Authority, Client Certificate & Client Private Key to root-ca.pem, test.pem & test.pem accordingly and I am able to connect. How can i specify the root-ca.pem & test.pem correctly in mongoclientoptions to connect to my mongo?

This is my mongod.conf

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1
  tls:
    mode: requireTLS
    certificateKeyFile: C:\TLSServerMongo\test.pem
    CAFile: C:\TLSServerMongo\root-ca.pem
    clusterFile: C:\TLSServerMongo\test.pem
    allowInvalidCertificates: true
    FIPSMode : false

This is my mongoclientoptions

   @Bean
    public MongoClientOptions mongoClientOptions() {
        MongoClientOptions.Builder mongoClientOptions = MongoClientOptions.builder().sslInvalidHostNameAllowed(true).sslEnabled(true);
        try {
//            String fileName = directory + RDS_COMBINED_CA_BUNDLE;
            String fileName = "C:\\TLSServerMongo\\test.pem";
            InputStream is = new FileInputStream(fileName);
            // You could get a resource as a stream instead.

            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            X509Certificate caCert = (X509Certificate) cf.generateCertificate(is);

            TrustManagerFactory tmf = TrustManagerFactory
                    .getInstance(TrustManagerFactory.getDefaultAlgorithm());
            KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
            ks.load(null); // You don't need the KeyStore instance to come from a file.
            ks.setCertificateEntry("caCert", caCert);

            tmf.init(ks);

            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, tmf.getTrustManagers(), null);
            mongoClientOptions.sslContext(sslContext);
        } catch (Exception e) {
            LOGGER.error(e.getMessage());
        }


        return mongoClientOptions.build();
    }

This is my MongoClient

  public @Bean
    MongoClient mongoClient() {
        List<MongoCredential> allCred = new ArrayList<>();
        allCred.add(MongoCredential.createCredential(username, database, password.toCharArray()));
        MongoClient client = new MongoClient((new ServerAddress(this.myHost, this.myPort)), allCred, mongoClientOptions());
        client.setWriteConcern(WriteConcern.ACKNOWLEDGED);

        return client;
    }
