提供者接口：DomeService.java
package com.wengen.dubbo_provider_test.service;
public interface DomeService {

}
提供者接口实现：DomeServiceImpl.java
package com.wengen.dubbo_provider_test.service.impl;
import com.wengen.dubbo_provider_test.service.DomeService;
public class DomeServiceImpl implements DomeService {
@Override
public String sayHello(String name) {

}
提供者启动类：DomeServiceTest.java
package com.wengen.dubbo_provider_test;
import java.io.IOException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class DomeServiceTest {
public static void main(String[] args)throws IOException {

context.start();
//任意键退出
System.in.read();
}
}
消费者启动类：DomeServiceConsumerTest.java
package com.wengen.dubbo_provider_test;
import java.io.IOException;
