功能区负载平衡算法 [英] Ribbon load balance algorithms

问题描述

我在微服务项目中将Spring Cloud与NetflixOSS一起使用.另外，我将功能区与Feign Client一起用作客户端负载平衡器.我想知道，是否有可能为Ribbon实施或选择不同类型的负载平衡算法?因为据我了解，默认值为循环轮询.

I am using Spring Cloud with NetflixOSS in my microservice project. Also, I am using Ribbon with Feign Client as my client side load balancer. I was wondering, is there any possibility to implement or choose different types of load balancing algorithms for Ribbon? Because as I understood, the default is round robin.

提前谢谢！

推荐答案

是的，有可能.有关如何自定义的完整详细信息，请参见文档.对于@FeignClient("foo")和随机负载平衡规则，您可以执行以下操作:

Yes, it is possible. See the docs for full details how to customize. For a @FeignClient("foo") and a random load-balancing rule you could do:

@Configuration
@RibbonClient(name = "foo", configuration = FooConfiguration.class)
public class TestConfiguration {
}

@Configuration
public class FooConfiguration {
    @Bean
    public IRule ribbonRule(IClientConfig config) {
        IRule rule = new RandomRule();
        rule.initWithNiwsConfig(config);
        return rule;
    }
}
