application.yml配置
|
eureka: client: serviceUrl: defaultZone: http://localhost:8888/eureka/ server: port: 8764 spring: application: name: service-order |
编写service,调用service-member
|
@SuppressWarnings("unchecked") @Service public class MemberService { @Autowired RestTemplate restTemplate;
public List<String> getOrderByUserList() { return restTemplate.getForObject("http://service-member/getUserList", List.class); } } |
演示效果
|
@EnableEurekaClient @SpringBootApplication public class AppOrder {
public static void main(String[] args) { SpringApplication.run(AppOrder.class, args); }
@Bean @LoadBalanced RestTemplate restTemplate() { return new RestTemplate(); }
} |
在工程的启动类中,通过@EnableDiscoveryClient向服务中心注册；并且向程序的ioc注入一个bean: restTemplate;并通过@LoadBalanced注解表明这个restRemplate开启负载均衡的功能。
