Eureka Server-列出所有注册的实例 [英] Eureka Server - list all registered instances

问题描述

我有一个Spring Boot应用程序，它也是一个Eureka服务器.我想列出已注册到此Eureka服务器的所有实例.我该怎么办?

I have a Spring Boot application that is also a Eureka Server. I want to list all instances that have been registered to this Eureka Server. How do I do it?

推荐答案

使用EurekaServerContextHolder.getInstance().getServerContext().getRegistry()获取registry，然后使用registry列出所有Applications

Fetch the registry using EurekaServerContextHolder.getInstance().getServerContext().getRegistry() then use the registry to list all Applications

PeerAwareInstanceRegistry registry = EurekaServerContextHolder.getInstance().getServerContext().getRegistry();
    Applications applications = registry.getApplications();

    applications.getRegisteredApplications().forEach((registeredApplication) -> {
        registeredApplication.getInstances().forEach((instance) -> {
            System.out.println(instance.getAppName() + " (" + instance.getInstanceId() + ") : " + response);
        });
    });
