hadoop--RPC应用实例

一.服务器端程序：

package rpc;

public interface LoginService {
	
	public static final long versionID= 1L;
	public String login(String username,String password);
	
	

}

确定业务接口

package rpc;

public class LoginServiceImpl implements LoginService {

	@Override
	public String login(String username, String password) {
		
		return username+" successful login";
		
	}

}

确定业务实现

package rpc;
import java.io.IOException;

import org.apache.hadoop.HadoopIllegalArgumentException;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.ipc.RPC;
import org.apache.hadoop.ipc.RPC.Builder;
import org.apache.hadoop.ipc.RPC.Server;

public class ServiceStrart {
	
	public static void main(String[] args) throws HadoopIllegalArgumentException, IOException {
		Builder builder = new RPC.Builder(new Configuration());
		builder.setBindAddress("192.168.245.129").setPort(10000).setProtocol(LoginService.class).setInstance(new LoginServiceImpl());
		Server server = builder.build();
		
		server.start();
		
	}
	

}

服务器端开始运行程序

二.客户端程序

package rpc;

public interface LoginService {
	
	public static final long versionID= 1L;
	public String login(String username,String password);
	
	
	
}

业务接口类需要和服务器端一致

package rpc;

import java.net.InetSocketAddress;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.ipc.RPC;

public class LoginController {
	
	
	//客户端
	public static void main(String[] args) throws Exception {
		LoginService proxy = RPC.getProxy(LoginService.class, 1L, new InetSocketAddress("192.168.245.129",10000), new Configuration());
		
		String result = proxy.login("bluefat", "123");
		
		
		System.out.println(result);
	}
	

}

客户端发起请求
