在工程bin目录下使用 rmic 命令
反编译以后
package rmi;
import java.lang.reflect.Method;
import java.rmi.Remote;
import java.rmi.RemoteException;
import java.rmi.UnexpectedException;
import java.rmi.server.RemoteObject;
import java.rmi.server.RemoteRef;
import java.rmi.server.RemoteStub;
//实现和真实对象相同的接口
// RemoteStub 类是客户机 stub 的公共超类，提供支持大量远程引用语义的框架
public final class HelloImpl_Stub extends RemoteStub
implements IHello, Remote

catch (NoSuchMethodException localNoSuchMethodException)

显然 HelloImpl_Stub 是 HelloImpl 的一个代理。
动态生成HelloImpl_Stub 的过程， 就是动态创建代理的过程。
