Spring Cloud Netflix Eureka找不到eureka-js实例

Question

我在Spring有3个微服务：

• 网飞尤里卡
• 制片人
• 消费者

和另一个用Eureka-js-client用NodeJs编写的微服务

null

List<ServiceInstance> instances=discoveryClient.getInstances("employee-producer");
    ServiceInstance serviceInstance=instances.get(0);

List<ServiceInstance> instances=discoveryClient.getInstances("node-microservice");
    ServiceInstance serviceInstance=instances.get(0);

const Eureka = require('eureka-js-client').Eureka;
const express = require('express');
const server = express();
server.use(express.json());
server.use(function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    next();
});
server.listen(3001);
server.get('/', function (req, res) {
    res.send("CIaooo");
});



// example configuration
const client = new Eureka({
    // application instance information
    instance: {
        app: 'node-microservice',
        hostName: 'localhost',
        ipAddr: '127.0.0.1',
        port:  {
            '$': 3001,
            '@enabled': 'true',
        },
        vipAddress: 'jq.test.something.com',
        statusPageUrl: 'http://localhost:3001/info',
        dataCenterInfo:  {
            '@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo',
            name: 'MyOwn',
        }
    },
    eureka: {
        // eureka server host / port
        host: 'localhost',
        port: 8761,
        servicePath: '/eureka/apps/'
    },
});

client.logger.level('debug');

client.start(function(error){
    console.log(error || 'complete')});

我的代码怎么了？

Answer 1

问题是在instance对象中，我没有编写instanceId（任何地方都没有提到）。我在抓取代码时发现了这个解决方案，并且在另一个项目中也有这个字段

instance: {
        app: 'node-microservice',
        instanceId: 'nodemicroservice',
        hostName: 'localhost',
        ipAddr: '127.0.0.1',
        port:  {
            '$': 3001,
            '@enabled': 'true',
        },
        vipAddress: 'nodemicroservice',
        statusPageUrl: 'http://localhost:3001/info',
        dataCenterInfo:  {
            '@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo',
            name: 'MyOwn',
        },
        registerWithEureka: true,
        fetchRegistry: true
    },
