ribbon在有eureka的情况下, 可以不使用eureka, 挺简单, 直接上代码

application.xml

server:  port: 7002spring:  # 设置eureka中注册的名称, 全小写, 否则大小写混杂出现问题  application:    name: microservice-consumer-movie-ribben-ymllogging:  level:    root: INFO    org.hibernate: INFO    org.hibernate.type.descriptor.sql.BasicBinder: TRACE    org.hibernate.type.descriptor.sql.BasicExtractor: TRACE    com.itmuch: DEBUGeureka:  client:    serviceUrl:      defaultZone: http://wenbronk:abc@localhost:8761/eureka  # 添加注册中心中的ip代替主机名  instance:    prefer-ip-c: true    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}    statusPageUrlPath: ${management.context-path}/info    healthCheckUrlPath: ${management.context-path}/health# 在ribbon中禁用eurekaribbon:  eureka:   enabled: false# 自定义ribbonclient, 不使用eureka, 使用这个配置microservice-provider-user:  ribbon:    listOfServers: localhost:7901

2, MovieController中使用此方法测试:

@RequestMapping("/movie/{id}")    public User findById(@PathVariable Long id) {        ServiceInstance instance = this.loadBalancerClient.choose("microservice-provider-user");        URI storesUri = URI.create(String.format("http://%s:%s", instance.getHost(), instance.getPort()));        System.out.println("111: " + instance.getServiceId() + ": " + instance.getHost() + ": " + instance.getPort());        return null;//        return restTemplate.getForObject("http://microservice-provider-user/simple/" + id, User.class);    }

客户端发起请求后 , 可看到日志里面只有 7901 端口在被访问, 注释掉yml中的最后2项配置, 就可以看到eureka默认的轮询配置
