收集整理的這篇文章主要介紹了
获取商品列表(Feign)
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
localhost:8010/productListlocalhost:7900/product/listlocalhost:7901/product/list商品服務和數據庫打交道,你看這邊SQL語句已經打印出來了,而訂單服務是要去調用它的,我們這里專門打印一個日志出來
package com.learn.cloud.controller;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;import com.learn.cloud.bean.ProductInfo;
import com.learn.cloud.client.ProductFeignClient;@RestController
public class FeignClientController {@Autowiredprivate ProductFeignClient productFeignClient;@GetMapping("/getProductMsg")public String findById() {String productMsg = this.productFeignClient.productMsg();System.out.println(productMsg);return productMsg;}@GetMapping("/productList")public List<ProductInfo> productList() {List<ProductInfo> productInfoList = this.productFeignClient.productList();System.out.println(productInfoList);return productInfoList;}
}
package com.learn.cloud.client;import java.util.List;import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;import com.learn.cloud.bean.ProductInfo;@FeignClient(name = "product")
public interface ProductFeignClient {@RequestMapping(value = "/msg", method = RequestMethod.GET)public String productMsg();@RequestMapping(value = "/product/list", method = RequestMethod.GET)public List<ProductInfo> productList();
}
package com.learn.cloud.controller;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import com.learn.cloud.entity.ProductInfo;
import com.learn.cloud.service.ProductService;@RestController
@RequestMapping("/product")
public class ProductController {@Autowiredprivate ProductService productService;/*** 1. 查詢所有在架的商品*/@GetMapping("/list")public List<ProductInfo> list() {//1. 查詢所有在架的商品List<ProductInfo> productInfoList = productService.findUpAll();return productInfoList;}}
