KerberosRestTemplate does not scale well

[Marat-Tim]

I want to create a KerberosRestTemplate extension with userPrincipal, password, and loginOptions parameters. I also want to configure the timeout. Currently, this requires copying classes and methods, as they are private static. This means that you have to copy the entire class code

But I want it to be

import java.util.Map;

import org.apache.hc.client5.http.config.ConnectionConfig;
import org.apache.hc.client5.http.impl.classic.HttpClientBuilder;
import org.apache.hc.client5.http.impl.io.PoolingHttpClientConnectionManager;
import org.apache.hc.client5.http.impl.io.PoolingHttpClientConnectionManagerBuilder;
import org.apache.hc.core5.util.Timeout;
import org.springframework.security.kerberos.client.KerberosRestTemplate;

public class CustomKerberosRestTemplate extends KerberosRestTemplate {
    public CustomKerberosRestTemplate(
            String userPrincipal,
            String password,
            Map<String, Object> loginOptions
    ) {
        super(null, userPrincipal, password, loginOptions);
    }

    @Override
    protected void customizeHttpClient(HttpClientBuilder builder) {
        PoolingHttpClientConnectionManager connectionManager = PoolingHttpClientConnectionManagerBuilder.create()
                .setDefaultConnectionConfig(ConnectionConfig.custom()
                        .setSocketTimeout(Timeout.ofSeconds(10))
                        .setConnectTimeout(Timeout.ofSeconds(10))
                        .build())
                .build();
        builder.setConnectionManager(connectionManager);
    }
}
