Ribbon的配置

1.注解配置

@RibbonClient(name = "xxx",configuration = XxxRibbonConfig.class)
public class XxxRibbonConfig {

    String listOfServers = "http://192.168.99.100:8080,http://192.168.99.101:8080";

    @Bean
    public ServerList<Server> ribbonServerList() {
        List<Server> list = Lists.newArrayList();
        if (!Strings.isNullOrEmpty(listOfServers)) {
            for (String s: listOfServers.split(",")) {
                list.add(new Server(s.trim()));
            }
        }
        return new StaticServerList<Server>(list);
    }
}

2.启动类配置

@SpringCloudApplication
@RibbonClients(value = {
        @RibbonClient(name = "xxx",configuration = XxxRibbonConfig.class),
        @RibbonClient(name = "demo",configuration = DemoRibbonConfig.class)
})
public class DemoServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoServiceApplication.class, args);
    }
}

3.属性配置

service-hi:
 ribbon:
  ReadTimeout: 1000
  SocketTimeout: 1000
  ConnectTimeout: 1000
  MaxAutoRetries: 0
  MaxAutoRetriesNextServer: 1
  eureka:
    enabled: true

4.设置resttemplate的超时时间（这个超时时间不知道是否与熔断有关）

package com.client;

import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

@Configuration
public class RibbonConf {

    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
 //return  new RestTemplate();

        SimpleClientHttpRequestFactory simpleClientHttpRequestFactory = new SimpleClientHttpRequestFactory();
        simpleClientHttpRequestFactory.setConnectTimeout(10000);
        simpleClientHttpRequestFactory.setReadTimeout(10000);
        return new RestTemplate(simpleClientHttpRequestFactory);

    }

}
