出现了创建bean的错误

图片描述
serviceAPI的路径问题已经排查了，没有问题，下面是具体错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘quickstartConsumer’ defined in file [/Users/GreenArrow/Desktop/springbootdubbo/consumer/target/classes/com/greenarrow/springboot/dubbo/consumer/quickstart/QuickstartConsumer.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: quickstartConsumer; nested exception is com.alibaba.dubbo.rpc.RpcException: Fail to create remoting client for service(dubbo://localhost:20880/com.greenarrow.springboot.dubbo.ServiceAPI?application=dubbo-spring-boot-starter&codec=dubbo&dubbo=2.6.0&heartbeat=60000&interface=com.greenarrow.springboot.dubbo.ServiceAPI&methods=sendMessage&pid=22339&register.ip=125.211.213.133&side=consumer&timestamp=1578404241358): client(url: dubbo://localhost:20880/com.greenarrow.springboot.dubbo.ServiceAPI?application=dubbo-spring-boot-starter&codec=dubbo&dubbo=2.6.0&heartbeat=60000&interface=com.greenarrow.springboot.dubbo.ServiceAPI&methods=sendMessage&pid=22339&register.ip=125.211.213.133&side=consumer&timestamp=1578404241358) failed to connect to server localhost/127.0.0.1:20880, error message is:connection timed out

他这里是说超时了，我之前出过一次错误，是因为serviceAPI路径不一样，改回来后成功过一次，然后没有动过，吃完饭回来就出现了这个问题，啥都没有动过。。。。。
QuickstartConsumer:

package com.greenarrow.springboot.dubbo.consumer.quickstart;

import com.alibaba.dubbo.config.annotation.Reference;
import com.greenarrow.springboot.dubbo.ServiceAPI;
import org.springframework.stereotype.Component;

/**
 * @author greenArrow
 * @version 1.0
 * @date 2020/1/7 7:27 PM
 */
@Component
public class QuickstartConsumer  {
    @Reference(url = "dubbo://localhost:20880")
    private ServiceAPI serviceAPI;

    public void sendMessage(String message){
        System.out.println(serviceAPI.sendMessage(message));
    }
}

QuickstartServiceImpl:

package com.greenarrow.springboot.dubbo.provider.quickstart;

import com.alibaba.dubbo.config.annotation.Service;
import com.greenarrow.springboot.dubbo.ServiceAPI;
import org.springframework.stereotype.Component;

/**
 * @author greenArrow

 */
@Component
@Service(interfaceClass = ServiceAPI.class)
public class QuickStartServiceImpl implements ServiceAPI {
    @Override
    public String sendMessage(String message) {
        return "quickstart-provider-message=" + message;
    }
}

问题其实和我上一次提的问题一样，是也是连接time out的问题，但是我发现一个奇怪的现象，这种time out问题出现不定时的，我把电脑重启了然后解决了。。。。。我怀疑是电脑配置的问题，然后还有dubbo.consumer.timout这个设置问题，他默认是1000，我调成了30000
