RPC基础知识
什么是RPC?
RPC（Remote Procedure Call Protocol）——远程过程调用协议，它是一种通过网络从远程计算机程序上请求服务，而不需要了解底层网络技术的协议。
RPC协议假定某些传输协议的存在，如TCP或UDP，为通信程序之间携带信息数据。在OSI网络通信模型中，RPC跨越了传输层和应用层。
RPC使得开发包括网络分布式多程序在内的应用程序更加容易。
RPC的模型
C/S模式
基于传输层协议(例如TCP/IP) 远程调用不是新的一种数据传输协议
事件响应基本模型(请求、计算、响应)
RPC设计的目的
通过固定的协议调用非本机的方法
提供不同语言程序之间通信
可以在不了解底层通信,像本地方法一样调用
RPC框架完全封装了网络传输以及其他细节,比如Spring 的RPC框架在调用远程对象的方法时就像调用Spring Bean 对象一样使用.
RPC的应用 大量的分布式应用都使用了RPC协议,比如分布式操作系统、分布式计算、分布式软件设计
RPC过程详解
RPC框架封装网络传输和其他细节,消费者和生产者不用去关心底层原理
消费者的代理层控制了整个RPC调用的流程,生成代理对象,封装请求报文,发送请求之类的
服务提供者会有一个监听模块,用来监听请求,并且按照约定,应该是注册了的服务才会被消费者调用到,注册的服务需要被反射调用到,用来计算结果
RPC框架的特点和设计模型
封装网络交互
尽量不要让RPC框架的使用者涉及到过多的网络层的开发
远程调用对象的代理
将接口代理的对象放入到Spring 容器之中,方便服务端开发
支持容器(Spring、Jetty等)
支持Spring容器,还有Jetty这样的web容器
可配置,可扩展
尽量做到可配置,可扩展
设计模型
Proxy代理层
用于对象的代理,对象的反射调用,RPC流程的控制
Serialize序列化层
将请求和结果做序列化和反序列化
Invoke网络模块
网络通信相关的处理
Container容器组件
支持代理层监听网络请求
代码实现

*/
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
// 获取类信息
Class interfaceClass = proxy.getClass().getInterfaces()[0];
// 封装成请求报文
String req = JsonFormatter.reqFormatter(interfaceClass, method.getName(), args[0]);
// 发送请求报文

// 解析响应报文

}
public ConsumerConfig getConfig() {
return config;
}
public void setConfig(ConsumerConfig config) {
this.config = config;
}
public String getClazz() {
return clazz;
}
public void setClazz(String clazz) {
this.clazz = clazz;
}
}
简单的RPC框架已经写好
然后我们准备一个公共的接口jar
pom里面什么依赖都没有
HelloInterface.java
package com.ibigsea.facade;
import com.ibigsea.vo.People;
/**
* 定义一个接口,如此而已
* @author bigsea
*
*/
public interface HelloInterface {
public String speak(People people);
}
People.java
package com.ibigsea.vo;
import java.io.Serializable;
/**
* 实体
* @author bigsea
*
*/
public class People implements Serializable {
private static final long serialVersionUID = 1L;
private String name;
public People() {
}
public People(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
接口定义好了 ,我们可以开始弄服务提供者和服务消费者了
服务提供者

服务提供者这里输出了消费者请求的日志
14:44:33.117 [348984985@qtp-592983282-1 - /invoke] DEBUG org.mortbay.log - REQUEST /invoke on org.mortbay.jetty.HttpConnection@6e01b90

好了,这里的代码我会上传到我的github上面
