启动报Consider defining a bean of type ‘com.netflix.client.config.IClientConfig‘ in your configuration

使用springboot+springcloudnacos

启动项目，报错为：

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of method ribbonServerList in com.alibaba.cloud.nacos.ribbon.NacosRibbonClientConfiguration required a bean of type 'com.netflix.client.config.IClientConfig' that could not be found.


Action:

Consider defining a bean of type 'com.netflix.client.config.IClientConfig' in your configuration.

核心依赖包为：

	<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>

            <version>2.1.0.RELEASE</version>
        </dependency>

我并没有加ribbon和feign的配置呀，但是既然提示建议加上IClientConfig，那我就造一个：

import com.netflix.client.config.DefaultClientConfigImpl;
import com.netflix.client.config.IClientConfig;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
class IClientConfigComponent {
    @Bean
    public IClientConfig iClientConfig() {
        return new DefaultClientConfigImpl();
    }
}

这样就有IClientConfig这个bean了，再次启动不再报错。
