REST风格 获取商品的GET请求方式 **/ @GetMapping(value="/goods/{id}") @ResponseBody public Goods getGoods...(@Pathvariable("id") Long id){ Goods goods = goodsService.getGoods(id); return goods;...REST风格 PUT请求修改商品信息 **/ @GetMapping(value="/goods/{id}") @ResponseBody public Goods getGoods...(@Pathvariable("id") Long id,@RequestBody Goods goods){ Goods goods = goodsService.getGoods(id...的DELETE请求删除商品信息 **/ @GetMapping(value="/goods/{id}") @ResponseBody public String getGoods
参数就是你的微服务名字 @FeignClient(name= "client-goods") public interface goodsFeignClient { @RequestMapping("/getGoods.do...") public Object getGoods(); } 在控制器当中进行调用 @Autowired goodsFeignClient goodsFeignClient;...@RequestMapping("/getGoods.do") public ResponseResult getGoods(){ return ResponseResult.success...("操作成功", goodsFeignClient.getGoods()); } 启动访问localhost:5000/getGoods.do
在调用时, 就可以使用服务名称来进行调用 , 和之前的使用Eureka方式 是一样的 默认使用是轮询策略 @RequestMapping("/getGoods") public ResponseResult...getGoods() { String url="http://goods-provide/getGoods"; return ResponseResult.success...") public Object getGoods(); } 在控制器中注入，并调用 @Autowired private FeiginClient feiginClient;...@RequestMapping("/getGoods") public ResponseResult getGoods() { return ResponseResult.success...("操作成功", feiginClient.getGoods()); } 启动测试 3.单个参数请求 1.在goods中 编写带参数的请求 @RequestMapping
