### 一、Ribbon全局配置 ###

@RibbonClients注解配置导入全局Ribbon客户端默认设置

public class GlobalRibbonConfig {
    
        //负载均衡策略
        @Bean
        public IRule rule() {
            return new MicroServiceLoadBalanceRule();
        }
    
        //负载均衡器
        @Bean
        public <E extends Server> ILoadBalancer loadBalancer(IClientConfig config, ServerList<E> serverList, ServerListFilter<E> serverListFilter, IRule rule, IPing ping, ServerListUpdater serverListUpdater) {
    
            return new MicroServiceLoadBalancer<>(config, rule, ping, serverList, serverListFilter, serverListUpdater);
        }
    
        //IPing
        @Bean
        public IPing iping() {
            return new DummyPing();
        }
    
        //服务列表
        @Bean
        public ServerList<NacosServer> serverList(NacosDiscoveryProperties properties) {
            return new NacosServerList(properties);
        }
    
        //服务列表过滤器
        @Bean
        public ServerListSubsetFilter serverListFilter() {
            ServerListSubsetFilter filter = new ServerListSubsetFilter();
            return filter;
        }
    
    }
    
    @RibbonClients(defaultConfiguration = GlobalRibbonConfig.class)
    public class GlobalRibbonClientConfig {
        
    }

### 二、单个服务Ribbon配置 ###

@RibbonClient配置导入单个服务ribbon客户端配置

public class MicroRibbonConfig {
    
        @Bean
        public IPing iping() {
    
            return new DummyPing();
        }
    
        @Bean
        public <E extends Server> ILoadBalancer loadBalancer(IClientConfig config, ServerList<E> serverList, ServerListFilter<E> serverListFilter, IRule rule, IPing ping, ServerListUpdater serverListUpdater) {
    
            return new MicroServiceLoadBalancer<E>(config, rule, ping, serverList,
                    serverListFilter, serverListUpdater);
        }
    
        @Bean
        public IRule rule() {
    
            return new MicroServiceLoadBalanceRule();
        }
    
        //服务列表
        @Bean
        public ServerList<NacosServer> serverList(NacosDiscoveryProperties properties) {
            return new NacosServerList(properties);
        }
    
        //服务列表过滤器
        @Bean
        public ServerListSubsetFilter serverListFilter() {
            ServerListSubsetFilter filter = new ServerListSubsetFilter();
            return filter;
        }
    }
    
    
    @RibbonClient(name = "micro-service", configuration = MicroRibbonConfig.class)
    public class RibbonClientConfig {
    
    }
