springcloud-05-ribbon中不使用eureka

Posted 2020-09-19 bronk

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: 7002
spring:
  # 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-yml

logging:
  level:
    root: INFO
    org.hibernate: INFO
    org.hibernate.type.descriptor.sql.BasicBinder: TRACE
    org.hibernate.type.descriptor.sql.BasicExtractor: TRACE
    com.itmuch: DEBUG
eureka:
  client:
    serviceUrl:
      defaultZone: http://wenbronk:[email protected]: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eureka
ribbon:
  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
