weblogic rmi编程，提供一个案例

好的，关于weblogic rmi编程的案例，以下是一个简单的示例：

服务端代码：

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;

import weblogic.jndi.WLInitialContextFactory;

public class RmiServer {
    public static void main(String[] args) throws NamingException {
        String contextFactory = "weblogic.jndi.WLInitialContextFactory";
        String port = "7001";
        String serverUrl = "t3://localhost:" + port;
        String jndiName = "MyService";
        Context context = new InitialContext();

        context.addToEnvironment(Context.INITIAL_CONTEXT_FACTORY, contextFactory);
        context.addToEnvironment(Context.PROVIDER_URL, serverUrl);

        MyServiceImpl serviceImpl = new MyServiceImpl();

        context.rebind(jndiName, serviceImpl);

        System.out.println("Service started successfully...");
    }
}

客户端代码：

import java.rmi.RemoteException;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import weblogic.jndi.WLInitialContextFactory;

public class RmiClient {
    public static void main(String[] args) throws NamingException, RemoteException {
        String contextFactory = "weblogic.jndi.WLInitialContextFactory";
        String port = "7001";
        String serverUrl = "t3://localhost:" + port;
        String jndiName = "MyService";
        Context context = new InitialContext();

        context.addToEnvironment(Context.INITIAL_CONTEXT_FACTORY, contextFactory);
        context.addToEnvironment(Context.PROVIDER_URL, serverUrl);

        MyService myService = (MyService) PortableRemoteObject.narrow(
                context.lookup(jndiName),
                MyService.class
        );

        System.out.println(myService.sayHello("WebLogic RMI"));
    }
}

MyServiceImpl.java:

import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;

public class MyServiceImpl extends UnicastRemoteObject implements MyService {
    protected MyServiceImpl() throws RemoteException {
        super();
    }

    @Override
    public String sayHello(String name) throws RemoteException {
        return "Hello, " + name;
    }
}

MyService.java:

import java.rmi.Remote;
import java.rmi.RemoteException;

public interface MyService extends Remote {
    public String sayHello(String name) throws RemoteException;
}

这是一个基本的 WebLogic RMI 编程示例。 服务器将一个实现MyService接口的远程对象公开给客户端，然后客户端通过JNDI查找当前正在运行的服务器上的对象。客户端然后调用该对象的方法，并使用返回结果。
