2.3 写YML
server:
port: 80
2.4 主启动
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配置类
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 {
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
}
2.6 创建controller
@RestController
@RequestMapping("order")
@Slf4j
public class OrderController {
public static final String PAYMENT_URL = "http://localhost:8001";
@Resource
private RestTemplate restTemplate;
@GetMapping("payment/create")
public CommonResult<Payment> create(Payment payment){
CommonResult commonResult = restTemplate.postForObject(PAYMENT_URL + "/payment/create", payment, CommonResult.class);
return commonResult; //写操作
}
@GetMapping("get/{id}")
public CommonResult<Payment> getPayment(@PathVariable("id") Long id){
return restTemplate.getForObject(PAYMENT_URL+"/payment/get/"+id,CommonResult.class);
}
}
