Using RestTemplate, how to send the request to a proxy first so I can use my junits with JMeter?

I have a web service running on my dev box implemented using Spring-MVC 3.0. I have various JUnits that test against that service using RestTemplate. What I would like to do is have JMeter pick up those JUnits REST requests when I run them. However, to do that, I need to have Spring's RestTemplate send them to the proxy that I'm running JMeter on. So, the question is, how can I do that?

I've done something similar with CXF and their http:conduit and http:client stuff, but I really have no idea how to do this with Spring-MVC.

Spring has a good documentation using a Customizer to determine different proxy

public class ProxyCustomizer implements RestTemplateCustomizer {

    @Override
    public void customize(RestTemplate restTemplate) {
        final String proxyUrl = "proxy.example.com";
        final int port = 3128;

        HttpHost proxy = new HttpHost(proxyUrl, port);
        HttpClient httpClient = HttpClientBuilder.create().setRoutePlanner(new DefaultProxyRoutePlanner(proxy) {
            @Override
            protected HttpHost determineProxy(HttpHost target, HttpRequest request, HttpContext context)
                    throws HttpException {
                if (target.getHostName().equals("gturnquist-quoters.cfapps.io")) {
                    return super.determineProxy(target, request, context);
                }
                return null;
            }
        }).build();
        restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory(httpClient));

    }

}

and the call to apply the ProxyCustomizer is 

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
    return builder.additionalCustomizers(new ProxyCustomizer()).build();
}

Alternatively you can use runtime parameters:

jre -DproxySet=true -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8888
