## 如何替换 默认的轮询算法 ##

1、修改cloud-consumer-order80  
2、注意配置细节(不能放在启动类的包及其子包下)

3、新建package

4、上面包下新建MySelfRule规则类

@Configuration
    public class MySelfRule {
        
    
        @Bean
        public IRule myRule(){
        
            return new RandomRule();//定义为随机
        }
    }

5、主启动类添加@RibbonClient

@EnableEurekaClient
    @SpringBootApplication
    @RibbonClient(name = "CLOUD-PAYMENT-SERVICE",configuration = MySelfRule.class)
    public class OrderMain80 {
        
        public static void main(String[] args) {
        
            SpringApplication.run(OrderMain80.class,args);
        }
    }

6、测试：http://localhost/consumer/payment/get/31
