Sping云网关空路由

标签： java node.js spring netflix-eureka

我有一个使用Spring（2.1.2.RELEASE）和cloud（2.1.0.Release）在本地运行的MicroService环境，我想将NodeJs应用程序连接到Eureka，以便网关也可以为该服务提供流量。 Eureka服务器上的注册正常进行，但是spring网关无法解析地址，因此可以转发流量。感谢您的帮助

Spring Eureka Server（带有@EnableEurekaServer）

spring.application.name=eurekaserver
server.port=8761
eureka.instance.hostname=eureka
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/
logging.level.root=INFO

Spring Eureka Discovery application.properties配置（带有@EnableDiscoveryClient）

spring.application.name=microservicediscovery
server.port=8080
eureka.client.enabled=true
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
eureka.client.service-url.defaultZone=http://127.0.0.1:8761/eureka/
logging.level.root=Debug
spring.cloud.gateway.discovery.locator.enabled=true

对于NodeJS Eureka注册配置，我正在使用eureka-js-client 

const eurekaIP = '127.0.0.1';
const eurekaPort=8761;
const client = new Eureka({
    // application instance information
    instance: {
        app: 'nodeFileService',
        instanceId:'nodeFileServ',
        hostName: 'localhost',
        ipAddr: '127.0.0.1',
        port: {
            '$': 3000,
            '@enabled': true,
        },
        statusPageUrl: 'http://localhost:3000',
        vipAddress: 'jq.test.something.com',
        dataCenterInfo: {
            '@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo',
            name: 'MyOwn',
        },
    },
    eureka: {
        // eureka server host / port
        host: eurekaIP,
        port: eurekaPort,
        servicePath: '/eureka/apps/'
    },
});

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