    github地址：https://github.com/github-ygy/spring_cloud_test.git

ribbon-consumer

    依据springboot-cloud-2-eureka 快速启动ribbon消费     前提：     eureka-server ： 注册中心分片1（也是提供者），注册自己的helloworld服务     eureka-server-slave：注册中心分片2（也是服务提供者），注册自己的helloworld服务     eureka-client  ： 服务提供者，注册自己的getClient服务

appliction.properties

#####defaultZone 为 eureka分片其中之1的地址spring.application.name=ribbon-consumerserver.port= 8001eureka.client.serviceUrl.defaultZone=http://pear1:9998/eureka

Application

@SpringBootApplication@EnableDiscoveryClientpublic class RibbonConsumerApplication {    @Bean    @LoadBalanced     //负载均衡    public RestTemplate restTemplate() {        return new RestTemplate();    }    public static void main(String[] args) {        SpringApplication.run(RibbonConsumerApplication.class, args);    }}

controller

/** * Created by guoyao on 2017/8/8. */@RestControllerpublic class ConsumerController {    @Autowired    private RestTemplate restTemplate ;    @RequestMapping("/consumerServer")    public String consumerServer() {         //此方法为eureka—server ， eureka-server-slave 提供        return  restTemplate.getForEntity("http://SERVER/helloworld?key=ygy",String.class).getBody();    }    @RequestMapping("/consumerClient")    public String consumerClient() {         //此方法为eureka—client提供        return  restTemplate.getForEntity("http://client/getClient?key=client",String.class).getBody();    }}

输出

//localhost:8001/// 调用consumerServer 2次，consumerClient一次eureka—server：  this is server master ! eureka—server-salve：  this is server slave !eureka-client ： this is eureka client server 

自定义ribbon负载

application

@SpringBootApplication@RibbonClient(name = "client",configuration =CustomerRibbonConfig.class)@EnableDiscoveryClientpublic class RibbonConsumerApplication {    @Bean    @LoadBalanced     //负载均衡    public RestTemplate restTemplate() {        return new RestTemplate();    }    public static void main(String[] args) {        SpringApplication.run(RibbonConsumerApplication.class, args);    }}
