### 情景 ###

在整合nacos项目时，启动发现报错：

Bean of type 'com.netflix.client.config.IClientConfig' that could not be found

导致项目无法启动。

### 解决办法 ###

在网上看到一个解决办法，新建一个类实现IClientConfig，但是别急，经过我的测试，虽然能启动了，但是在负载时并没有用，例子如下：

import java.util.Map;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.stereotype.Component;
    
    import com.netflix.client.config.IClientConfig;
    import com.netflix.client.config.IClientConfigKey;
    import com.netflix.loadbalancer.IRule;
    import com.netflix.loadbalancer.RandomRule;
    
    @Component
    public class RibbonConfiguration implements IClientConfig {
    
    	@Bean
    	public IRule ribbonRule(IClientConfig config) {
    		// 随机算法
    		return new RandomRule();
    	}
    
    	@Override
    	public boolean containsProperty(IClientConfigKey arg0) {
    		// TODO Auto-generated method stub
    		return false;
    	}
    
    	@Override
    	public <T> T get(IClientConfigKey<T> arg0) {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public <T> T get(IClientConfigKey<T> arg0, T arg1) {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public String getClientName() {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public String getNameSpace() {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public Map<String, Object> getProperties() {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public Object getProperty(IClientConfigKey arg0) {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public Object getProperty(IClientConfigKey arg0, Object arg1) {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public boolean getPropertyAsBoolean(IClientConfigKey arg0, boolean arg1) {
    		// TODO Auto-generated method stub
    		return false;
    	}
    
    	@Override
    	public int getPropertyAsInteger(IClientConfigKey arg0, int arg1) {
    		// TODO Auto-generated method stub
    		return 0;
    	}
    
    	@Override
    	public String getPropertyAsString(IClientConfigKey arg0, String arg1) {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public void loadDefaultValues() {
    		// TODO Auto-generated method stub
    
    	}
    
    	@Override
    	public void loadProperties(String arg0) {
    		// TODO Auto-generated method stub
    	}
    
    	@Override
    	public String resolveDeploymentContextbasedVipAddresses() {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public <T> IClientConfig set(IClientConfigKey<T> arg0, T arg1) {
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    	@Override
    	public void setProperty(IClientConfigKey arg0, Object arg1) {
    		// TODO Auto-generated method stub
    
    	}
    }

后来我发现 其实是版本的问题，切换一下版本就可以了，这里贴我用的版本，大家可以参考一下：

后面整理了一个新版本的，或许对大家有点帮助。
