[GitHub] [dubbo] zuonidelaowang opened a new issue #9293: 配置禁用元数据中心后，comsumer启动报错，我该怎么配置？
zuonidelaowang opened a new issue #9293:
URL: https://github.com/apache/dubbo/issues/9293
dubbo 3.0.4
nacos 2.0+
```
dubbo:
application:
name: ${server.name}
metadata-type: local
protocol:
port: -1
name: dubbo
registry:
address: nacos://${nacos.server}?registry-type=service
parameters:
namespace: ${nacos.namespace}
use-as-metadata-center: false
use-as-config-center: false
```
provider配置了以下参数，不想在nacos配置中心显示dubbo的配置文件
```
metadata-type: local
use-as-metadata-center: false
use-as-config-center: false
```
comsumer启动的时候报以下错误
```

@zuonidelaowang
服务自省架构中consumer需要知道接口到应用名的映射，这个映射信息默认由provider在发布服务时添加到配置中心，如果用nacos的话，可以看到一条类型为mapping的配置项。
如果你觉得配置中心压力太大了，可以在provider端设置` use-as-metadata-center: false`，并在consumer的接口处声明该接口对应的应用名，由consumer自己维护这个映射关系，如
` @DubboReference(providedBy = "spring-boot-demo-provider",version = "1.0.0",group = "group1") `
希望可以解决你的问题。

之前碰到同样的问题，无法解决，只能不使用`metadata-type: local`的方式，用nacos当作元数据中心。 目前nacos负载过大，经常出现超时。

但是业务调用出现问题了，comsumer 调用 provider 有问题， 你用应用级别的注册方式，不要用接口的方式注册
```
