SpringCloud Day01---微服务架构编码构建（三）

@RestController
@Slf4j
public class OrderController {
    public static final String PAYMENT_URL = "http://localhost:8001";
    @Resource
    private RestTemplate restTemplate;
    @GetMapping("/consumer/payment/create")客户端用浏览器是get请求，但是底层实质发送post调用服务端8001
    public CommonResult<Payment> create(Payment payment){
        return restTemplate.postForObject(PAYMENT_URL+"/payment/create",payment,CommonResult.class);
    }
    @GetMapping("/consumer/payment/get/{id}")
    public CommonResult<Payment> getPayment(@PathVariable("id") Long id){
        return restTemplate.getForObject(PAYMENT_URL+"/payment/get/"+id,CommonResult.class);
    }
}
