System.in.read (); / / Press any key to exit

}

Public class Consumer

{

Public static void main (String [] args) throws Exception

{

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext ("dubbo-dubbo-consumer.xml")

Context.start ()

DemoService demoService = (DemoService) context.getBean ("demoService"); / / get remote service agent

String hello = demoService.sayHello ("world"); / / execute remote methods

System.err.println (hello); / / display the result of the call

}

}

Directly connected mode

Service provider, does not need to register the service with the registry, and adds registry= "NumberA" to the dubbo:service configuration

At the same time, service consumers do not need to discover services through the registry and add url= "dubbo://localhost:20880" directly connected addresses to the dubbo:reference configuration.

Instead, the connection address is obtained through the registry.
