In my existing code we are using

public HealthCheckServiceInstanceListSupplier(ServiceInstanceListSupplier delegate,
                                                      LoadBalancerProperties.HealthCheck healthCheck,
                                                      BiFunction<ServiceInstance,String,reactor.core.publisher.Mono<Boolean>> aliveFunction)

How I have upgraded my spring cloud loadbalancer to 4.1.1

The above method is Deprecated in new version.

New method:

public HealthCheckServiceInstanceListSupplier(ServiceInstanceListSupplier delegate,
                                          ReactiveLoadBalancer.Factory<ServiceInstance> loadBalancerClientFactory,
                                          BiFunction<ServiceInstance,String,reactor.core.publisher.Mono<Boolean>> aliveFunction)

Now How can I get ReactiveLoadBalancer.Factory loadBalancerClientFactory

Thanks for the help
