相关介绍:  RMI全称是Remote Method Invocation,即远程方法调用.它是一种计算机之间利用远程对象互相调用,从而实现双方通讯的一种通讯机制.使用这种机制,某一台计算机(虚拟机)上的对象可以调用另外一台计算机(虚拟机)上的对象来获取远程数据.RMI是Enterprise JavaBeans的支柱,是建立分布式Java应用程序的方便途径.在过去,TCP/IP套接字通讯是远程通讯的主要手段,但此开发方式没有使用面向对象的方式实现开发,在开发一个如此的通讯机制时往往令程序员感觉到…

RMI 相关知识RMI全称是Remote Method Invocation-远程方法调用,Java RMI在JDK1.1中实现的,其威力就体现在它强大的开发分布式网络应用的能力上,是纯Java的网络分布式应用系统的核心解决方案之一.其实它可以被看作是RPC的Java版本.但是传统RPC并不能很好地应用于分布式对象系统.而Java RMI 则支持存储于不同地址空间的程序级对象之间彼此进行通信,实现远程对象之间的无缝远程调用.RMI目前使用Java远程消息交换协议JRMP(Java Remote…

RMI 指的是远程方法调用 (Remote Method Invocation) 1. RMI的原理: RMI系统结构,在客户端和服务器端都有几层结构. 方法调用从客户对象经占位程序(Stub).远程引用层(Remote Reference Layer)和传输层(Transport Layer)向下,传递给主机,然后再次经传 输层,向上穿过远程调用层和骨干网(Skeleton),到达服务器对象. 占位程序扮演着远程服务器对象的代理的角色,使该对象可被客户激活. 远程引用层处理语义.管理单一或多重…

Java RMI简介: 它是Java的一个核心API和类库,允许一个Java虚拟机上运行的Java程序调用不同虚拟机上运行的对象中的方法,即使这两个虚拟机运行于物理隔离的不同主机上. Java RMI在JDK1.1版本已经存在,是非常重要的底层技术. 下面通过一个简单的例子来测试: package com.tc.remote; import java.rmi.Remote; import java.rmi.RemoteException; /** * 一个远程调用接口RMIQueryStatus…

相信大家看到这个标题也是一头雾水了. 这个问题主要是我在项目中遇到了一个问题, 然后我通过搜索引擎搜索的关键词进而找到了answer, 我先描述一下我遇到的问题: 做项目的时候我发现log时常没有输出, 就是有log文件生成但是里面并没有任何内容. 我好奇这个问题并开始寻找问题原因. 项目中用的log类是.net提供的System.Diagnostics.TraceSource, 并不是像我之前做项目时候都是引用的自己写的log类, 这个类我之前也没有用过, 从网上查了一些资料发现还是很灵活的,…

1.RMI是远程方法调用的简称,像其名称暗示的那样,它能够帮助我们查找并执行远程对象,通俗的说,远程调用就像一个class放在A机器上,然后在B机器中调用这个class的方法. 2.EMI术语 在研究代码之前,我们来看看必须编写哪些代码: 远程对象:这个接口只定义了一个方法,我们应当明白的是,这个接口可以既包含方法的代码也包含方法的定义.远程对象包含要导出的每个方法的定义,并且实现Java.RMI中的远程接口. 远程对象实现:这是一个实现远程对象的类.如果实现了远程对象,就能够覆盖该对象中的所有…

前言 今天在开会时提到的一个概念,入职3个多月多注重在项目中使用C#的编程知识,一直没有很认真地过一遍C#的全部语法,当我们新人被问及是否了解Extension Method时,一时之间竟不能很通俗准确地描述.所以下面做个笔记吧.在空闲的时候还是要多看看MSDN的文档以及C#高级编程,熟悉相关语法知识,做到知其然也知其所以然! 本篇可参考:https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-st…
