一、 Ribbon简介
Ribbon是Netflix发布的负载均衡器，它有助于控制HTTP和TCP的客户端的行为。为Ribbon配置服务提供者地址后，Ribbon就可基于某种负载均衡算法，自动地帮助服务消费者去请求。Ribbon默认为我们提供了很多负载均衡算法，例如轮询、随机等。当然，我们也可为Ribbon实现自定义的负载均衡算法。
在Spring Cloud中，当Ribbon与Eureka配合使用时，Ribbon可自动从Eureka Server获取服务提供者地址列表，并基于负载均衡算法，请求其中一个服务提供者实例。展示了Ribbon与Eureka配合使用时的架构。
二、新建一个Eureka服务注册项目 springcloud-deepeureka
2.1、pom.xml依赖

@SpringBootApplication
@EnableEurekaClient
//@RibbonClient(name = "springcloud-user")
public class ConsumerRibbonApplication {
@Bean
@LoadBalanced
public RestTemplate restTemplate() {
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(ConsumerRibbonApplication.class, args);
}
}
3.3、测试数据实体User类
public class User {
private Long id;
private String username;
private String name;
private Short age;
private BigDecimal balance;
public Long getId() {
return this.id;
}
public void setId(Long id) {

}
public void setAge(Short age) {
this.age = age;
}
public BigDecimal getBalance() {
return this.balance;
}
public void setBalance(BigDecimal balance) {
this.balance = balance;
}
}
3.4、新建Controller访问
@RestController
public class RibbonController {
@Autowired
private RestTemplate restTemplate;
@Autowired
private LoadBalancerClient loadBalancerClient;
@GetMapping("/user/{id}")
public User findById(@PathVariable Long id) {
// http://localhost:7900/simple/
// VIP virtual IP
// HAProxy Heartbeat
return this.restTemplate.getForObject("http://springcloud-user/simple/" + id, User.class);
}
@GetMapping("/test")
public String test() {
ServiceInstance serviceInstance = this.loadBalancerClient.choose("springcloud-user");
System.out.println("111" + ":" + serviceInstance.getServiceId() + ":" + serviceInstance.getHost() + ":" + serviceInstance.getPort());
ServiceInstance serviceInstance2 = this.loadBalancerClient.choose("springcloud-user2");
System.out.println("222" + ":" + serviceInstance2.getServiceId() + ":" + serviceInstance2.getHost() + ":" + serviceInstance2.getPort());
return "1";
}
}
3.5、application.yml配置
server:
port: 8010
spring:
application:
name: springcloud-ribbon
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8081/eureka/
instance:

create table user(
id bigint generated by default as identity,
username varchar(40),
name varchar(20),
age int(3),
balance decimal(10,2),
primary key(id)
);

springcloud-user项目结构
五、测试: 依次启动项目
- 启动微服务Eureka项目：springcloud-deepeureka
- 启动ribbon微服务：springcloud-ribbon
- 启动user数据提供微服务：springcloud-user
六、访问Eureka服务测试
七、通过访问Ribbon负载分流服务测试查看访问数据
springcloud-user项目控制台打印结果

8.2、在启动一个user数据提供服务：启动方式如下
8.3、启动两个user服务后，再次访问Eureka服务查看
8.4、多次重复请求ribbon服务提供的数据请求访问路径
访问http://localhost:8010/user/1 ，可以得出ribbon默认采用轮询的方式进行负载均衡
8.5、通过切换两个user数据服务查看访问分流情况
名为springCloudUserApplication服务请求的情况
