Springcloud (5): Eureka metadata with Eureka Server's Rest Endpoint

First, Eureka Meta-data

1.1. Introduction

There are two types of metadata for Eureka: standard metadata and custom metadata.

Standard metadata refers to information such as host name, IP address, port number, status page, and health check, which are published in the service registry for calls between services.

Custom metadata can use the Eureka.instance.metadata-map configuration, which can be accessed in remote clients, but generally does not alter the behavior of the client unless the client knows what the metadata means.

1.2. Operation

Such as:

1.2.1, modifying the application.properties configuration of the Demo2

server.port=9093spring.application.name=demo2eureka.client.service-url.defaultzone=http://liuy1:9090/eureka/ eureka.instance.prefer-ip-address=true# display specified Ipeureka.instance.instance-id: ${spring.cloud.client.ipaddress}:${ Server.port} #元数据eureka. Instance.metadata-map.my-metada=zhangsan

1.2.2, Access in Demo1

/** * Query DEMO2 Service INFORMATION * @description query information of the DEMO2 service * @return * @throws Exception * @author I love big gold * @version 1.0 * @date: 2017 6  24th PM 4:25:15 */@GetMapping ("/demo-instance") public list<serviceinstance> Showinfo () throws Exception {return Discoveryclient.getinstances ("Demo2"); }

1.2.3, testing

Visit: http://localhost:9092/demo-instance

Second, Eureka server's Rest endpoint

Non-JVM microservices can use the rest endpoint to manipulate Eu-reka for registration and discovery. For details, please refer to http://projects.spring.io/spring-cloud/
