Spring Cloud Gateway查看实际路由后的路径

后台服务多个实例，在Spring Cloud Gateway中使用负载均衡算法访问其中的实例。

现在想要知道每次请求究竟访问了哪一个实例？

Spring Cloud Gateway使用LoadBalancerClientFilter处理lb开头的路由请求。其源码如下：

package org.springframework.cloud.gateway.filter;

// ...


@Deprecated
public class LoadBalancerClientFilter implements GlobalFilter, Ordered {

	
	public static final int LOAD_BALANCER_CLIENT_FILTER_ORDER = 10100;

	private static final Log log = LogFactory.getLog(LoadBalancerClientFilter.class);

	protected final LoadBalancerClient loadBalancer;

	private LoadBalancerProperties properties;

	public LoadBalancerClientFilter(LoadBalancerClient loadBalancer,
			LoadBalancerProperties properties) {
		this.loadBalancer = loadBalancer;
