测试

服务发现

@EnableDiscoveryClient 从 E 版开始，可省略

@RestController
@RequestMapping("/discovery")
@AllArgsConstructor
public class ClientDiscoveryController {

    private ClientDiscoveryService discoveryService;

    @GetMapping("/instance")
    public List<ServiceInstance> getInstance(@RequestParam(defaultValue = "cloud-alibaba-nacos") String serviceId){
       return discoveryService.getInstance(serviceId);
    }
}

@Service
@Slf4j
@AllArgsConstructor
public class ClientDiscoveryService {
    private final DiscoveryClient discoveryClient;

    public List<ServiceInstance> getInstance(String serviceId) {
        List<ServiceInstance> instances = discoveryClient.getInstances(serviceId);
        instances.forEach(instance->{
            log.info("instance host:[{}],instance port:[{}]",instance.getHost(),instance.getPort());
        });
        return instances;
    }
}
