Ribbon

ribbon实例自定义配置

①配置文件方式

#这里使用服务提供者的instanceName
my-producer:
  ribbon:
    # 代表Ribbon使用的负载均衡策略
    NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule
    # 每台服务器最多重试次数，但是首次调用不包括在内， Max number of retries on the same server (excluding the first try)
    MaxAutoRetries: 1
    # 最多重试多少台服务器，Max number of next servers to retry (excluding the first server)
    MaxAutoRetriesNextServer: 1
    # 无论是请求超时或者socket read timeout都进行重试，Whether all operations can be retried for this client
    OkToRetryOnAllOperations: true
    # Interval to refresh the server list from the source
    ServerListRefreshInterval: 2000
    # Connect timeout used by Apache HttpClient
    ConnectTimeout: 3000
    # Read timeout used by Apache HttpClient
    ReadTimeout: 3000

②java bean方式(与主目录结构同级)

自定义配置

package ribbon;

import com.netflix.loadbalancer.IRule;
import com.netflix.loadbalancer.RoundRobinRule;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class DefaultRibbonClientConfiguration {

    @Bean
    public IRule ribbonDefaultRule() {
        return new RoundRobinRule();
    }

}

配置定义好的配置

package cn.iocoder.springcloudnetflix.labx02.ribbondemo.consumer.config;

import org.springframework.cloud.netflix.ribbon.RibbonClient;
import org.springframework.cloud.netflix.ribbon.RibbonClients;
import org.springframework.context.annotation.Configuration;
import ribbon.DefaultRibbonClientConfiguration;
import ribbon.UserProviderRibbonClientConfiguration;

@Configuration
@RibbonClients(
        value = {
                @RibbonClient(name = "demo-provider", configuration = UserProviderRibbonClientConfiguration.class) // 客户端级别的配置
        },
        defaultConfiguration = DefaultRibbonClientConfiguration.class // 全局配置
)
public class RibbonConfiguration {
}
