yml 指定端口：

server:
  port: 9060

订单信息 OrderInfo.java:

@Data
@NoArgsConstructor
@AllArgsConstructor
public class OrderInfo {

    private Long productId;

}

价格信息 PriceInfo ：

@Data
public class PriceInfo {

    private Long id;

    private BigDecimal price;
}

OrderControl：

package com.nb.security.order;

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.client.RestTemplate;

@Slf4j
@RestController
@RequestMapping("/orders")
public class OrderController {

    private RestTemplate restTemplate = new RestTemplate();

    @PostMapping
    public OrderInfo create(@RequestBody OrderInfo info){
        //查询价格
        PriceInfo price = restTemplate.getForObject("http://localhost:9080/prices/"+info.getProductId(),PriceInfo.class);
        log.info("price is "+price.getPrice());
        return info;
    }

    @GetMapping
    public OrderInfo getInfo(@PathVariable Long id){
        log.info("getInfo: id is "+id);
        return new OrderInfo(id);
    }

yml指定端口

server:
  port: 9080

价格信息实体info类：

@Data
public class PriceInfo {

    private Long productId;

    private BigDecimal price;
}

价格微服务Controller：

/**
 * 价格服务
 */
@Slf4j
@RestController
@RequestMapping("/prices")
public class PriceController {

    @GetMapping("/{productId}")
    public PriceInfo getPrice(@PathVariable Long productId){
        log.info("product id is "+productId);
        PriceInfo info = new PriceInfo();
        info.setProductId(productId);
        info.setPrice(new BigDecimal(100));
        return info;
    }
}

启动两个服务，用postman请求下订单服务：

查看控制台日志，可以看到两个服务都已调通。
