2.微服務訂單

? 2.1?建cloud-order80

? 2.2?改POM文件

<?xml version="1.0" encoding="UTF-8"?>

? 2.3?寫YML

server:port: 80

? 2.4?主啟動

package org.example.cloud;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class OrderMain {public static void main(String[] args) {SpringApplication.run(OrderMain.class, args);}
}

? 2.5?config配置類

package org.example.cloud.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;@Configuration
public class ApplicationContextConfig {@Beanpublic RestTemplate getRestTemplate(){return new RestTemplate();}
}

? 2.6?創建controller

@RestController
@RequestMapping("order")
@Slf4j
public class OrderController {public static final String PAYMENT_URL = "http://localhost:8001";@Resourceprivate RestTemplate restTemplate;@GetMapping("payment/create")public CommonResult<Payment>   create(Payment payment){CommonResult commonResult = restTemplate.postForObject(PAYMENT_URL + "/payment/create", payment, CommonResult.class);return  commonResult; //寫操作}@GetMapping("get/{id}")public CommonResult<Payment> getPayment(@PathVariable("id") Long id){return restTemplate.getForObject(PAYMENT_URL+"/payment/get/"+id,CommonResult.class);}}
