dubbo-dubbo-test-api模块：

 IShowName接口：

package com.huidong.provider;

public interface IShowName {
    String showName();

    String showCal() throws InterruptedException;
}

dubbo-test-provider1模块：

# Dubbo Application
## The default value of dubbo.application.name is ${spring.application.name}
dubbo.application.name=${spring.application.name}

# Dubbo Protocol
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880

## Dubbo Registry
dubbo.registry.address=zookeeper://127.0.0.1:2181

server.port=7010


ShowNameImpl为IShowName接口的实现,实现类需要加 @DubboService注解
