springcloud-1.使用Eureka -robbon构建自动服务发现注册集群和消费者

1.使用Eureka组件创建服务中心Server_1@EnableEurekaServer //表示自己是一个server
@SpringBootApplication
public class EurekaserverApplication {

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

eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/ server:
port: 8764
spring:
application:
name: service-ribbon

通过eureka.client.registerWithEureka：false和fetchRegistry：false来表明自己是一个eureka server.

2.使用Eureka组件创建客服端Clinet_P_1,Clinet_P_2，即P表示生产者，服务提供者。并且指定服务中心的地址Server_1。@SpringBootApplication
@EnableEurekaClient //表示自己是一个client
@RestController
public class ServiceHiApplication {

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

@Value("${server.port}")
String port;
@RequestMapping("/hi")
public String home(@RequestParam String name) {
return "hi "+name+",i am from port:" +port;
}

}

3.使用ribbon组件创建客户端Client_C_1，C表示customer，服务消费者，并且指定服务中心的地址Server_1。
创建主类

@SpringBootApplication
@EnableDiscoveryClient
public class ServiceRibbonApplication {

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

@Bean
@LoadBalanced
RestTemplate restTemplate() {
return new RestTemplate();
}

}

调用远程服务@Service
public class HelloService {

@Autowired
RestTemplate restTemplate;

public String hiService(String name) {
return restTemplate.getForObject("http://SERVICE-HI/hi?name="+name,String.class);
}

}
配置文件
eureka: client: serviceUrl: defaultZone: http://localhost:8761/eureka/ server: port: 8764 spring: application: name: service-ribbon
