依赖：

        
        
            org.springframework.cloud
            spring-cloud-starter-openfeign

Client：配置调用服务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;
//调用的服务的名称,以及熔断后执行方法的类
//@FeignClient(name="service-vod",fallback = VodClientDefeat.class)

@FeignClient(name="service-business")
@Component
public interface ProductFeignClient {
    /**
     * 通过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);
    
}

调用示例：

 @Autowired
    private ProductFeignClient productFeignClient ;


@GetMapping(value = "test")
    @ApiOperation(value = "测试调用nacos服务")
    public void testnacos() throws Exception{
        Long spuId=123456L;
        Map sss=ProductFeignClient.loadEsProductBO(spuId);
        System.out.println(sss);
    }
