Spring Cloud Openfeign ribbon retry can not effect

Bug report

Spring Cloud version：Greenwich.SR2 Ribbon-core version：2.3.0

I want to use the retry mechanism of the ribbon, but it does not take effect after the retry attribute is configured.

After reading the source code, I found that the attribute specified in application.yml is not set to the corresponding attribute.

my application.yml：

spring-cloud-provider-application:
  ribbon:
    ConnectTimeout: 4000
    ReadTimeout: 4000
    OkToRetryOnAllOperations: true
    MaxAutoRetries: 3
    MaxAutoRetriesNextServer: 3

source code： org.springframework.cloud.openfeign.ribbon.FeignLoadBalancer#getRequestSpecificRetryHandler

@Override
    public RequestSpecificRetryHandler getRequestSpecificRetryHandler(
            RibbonRequest request, IClientConfig requestConfig) {
                // this condition is true
        if (this.ribbon.isOkToRetryOnAllOperations()) {
            return new RequestSpecificRetryHandler(true, true, this.getRetryHandler(),
                    requestConfig);
        }
        if (!request.toRequest().httpMethod().name().equals("GET")) {
            return new RequestSpecificRetryHandler(true, false, this.getRetryHandler(),
                    requestConfig);
        }
        else {
            return new RequestSpecificRetryHandler(true, true, this.getRetryHandler(),
                    requestConfig);
        }
    }     

com.netflix.client.RequestSpecificRetryHandler#RequestSpecificRetryHandler(boolean, boolean, com.netflix.client.RetryHandler, com.netflix.client.config.IClientConfig)

public RequestSpecificRetryHandler(boolean okToRetryOnConnectErrors, boolean okToRetryOnAllErrors, RetryHandler baseRetryHandler, @Nullable IClientConfig requestConfig) {
        Preconditions.checkNotNull(baseRetryHandler);
        this.okToRetryOnConnectErrors = okToRetryOnConnectErrors;
        this.okToRetryOnAllErrors = okToRetryOnAllErrors;
        this.fallback = baseRetryHandler;
        // this requestConfig is FeignOptionsClientConfig, it can not contains MaxAutoRetries attribute, so retry can not effect, i think requestConfig attribute should come from the clientConfig property of FeignLoadBalancer
        if (requestConfig != null) {
            if (requestConfig.containsProperty(CommonClientConfigKey.MaxAutoRetries)) {
                retrySameServer = requestConfig.get(CommonClientConfigKey.MaxAutoRetries); 
            }
            if (requestConfig.containsProperty(CommonClientConfigKey.MaxAutoRetriesNextServer)) {
                retryNextServer = requestConfig.get(CommonClientConfigKey.MaxAutoRetriesNextServer); 
            } 
        }
    }
