整合nacos時報錯IClientConf that could not be found

情景

在整合nacos項目時，啓動發現報錯：

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

導致項目無法啓動。

解決辦法

在網上看到一個解決辦法，新建一個類實現IClientConfig，但是別急，經過我的測試，雖然能啓動了，但是在負載時並沒有用，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) {
		// 隨機算法
		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

	}
}

 

 

後來我發現 其實是版本的問題，切換一下版本就可以了，這裏貼我用的版本，大家可以參考一下：
