Client：配置調用服務ProductFeignClient?

import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.Map;
//調用的服務的名稱,以及熔斷后執行方法的類
//@FeignClient(name="service-vod",fallback = VodClientDefeat.class)

@FeignClient(name="service-business")
@Component
public interface ProductFeignClient {
    /**
     * 通過spuId需要搜索的商品
     * @param spuId spuid
     * @return es保存的商品信息
     */
    @GetMapping(value = "/brand/selectAll")
    public Map loadEsProductBO(@RequestParam("spuId") Long spuId);
    
}

調用示例：

 @Autowired
    private ProductFeignClient productFeignClient ;


@GetMapping(value = "test")
    @ApiOperation(value = "測試調用nacos服務")
    public void testnacos() throws Exception{
        Long spuId=123456L;
        Map sss=ProductFeignClient.loadEsProductBO(spuId);
        System.out.println(sss);
    }
