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{ private static final long serialVersionUID = 2L; private static Method $method_helloWorld_0; private static Method $method_sayHelloToSomeBody_1; static { try { $method_helloWorld_0 = Remote.class.getMethod("helloWorld", new Class[0]); $method_sayHelloToSomeBody_1 = tmp50_47.getMethod("sayHelloToSomeBody", new Class[] { String.class }); } catch (NoSuchMethodException localNoSuchMethodException) { throw new NoSuchMethodError("stub class initialization failed"); } } public HelloImpl_Stub(RemoteRef paramRemoteRef) { super(paramRemoteRef); } public String helloWorld() throws RemoteException { Object localObject; try {
//调用真实对象的helloword方法 localObject = this.ref.invoke(this, $method_helloWorld_0, null, 32013462L); return ((String)localObject); } catch (RuntimeException localRuntimeException) { throw localRuntimeException; } catch (RemoteException localRemoteException) { throw localRemoteException; } catch (Exception localException) { throw new UnexpectedException("undeclared checked exception", localException); } } public String sayHelloToSomeBody(String paramString) throws RemoteException { try { Object localObject = this.ref.invoke(this, $method_sayHelloToSomeBody_1, new Object[] { paramString }, -1641805534L); return ((String)localObject); } catch (RuntimeException localRuntimeException) { throw localRuntimeException; } catch (RemoteException localRemoteException) { throw localRemoteException; } catch (Exception localException) { throw new UnexpectedException("undeclared checked exception", localException); } }}
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。
