篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了简单Tomcat HTTP RPC框架相关的知识，希望对你有一定的参考价值。

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

技术分享

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

技术分享

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

技术分享

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

技术分享

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

this.data = data;
}
public RpcException(Object data) {
super();
this.data = data;
}
public Object getData() {
return data;
}
}

HttpInvoke.java

package com.ibigsea.rpc.invoke;

try {

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();

HttpHost localhost = new HttpHost("localhost", 8080);
cm.setMaxPerRoute(new HttpRoute(localhost), 50);
// 创建httpClient
return HttpClients.custom().setConnectionManager(cm).build();
}
}

接下来就是代理成了,因为我们使用了jetty容器,所以这里对服务提供者的代理我们通过jetty的AbstractHandler来实现请求的处理

ProviderProxyFactory.java

[java] view plain copy

package com.ibigsea.rpc.proxy;
import java.io.IOException;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.mortbay.jetty.handler.AbstractHandler;
import org.mortbay.log.Log;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.ibigsea.rpc.config.ProviderConfig;
import com.ibigsea.rpc.container.HttpContainer;
import com.ibigsea.rpc.exception.RpcException;
import com.ibigsea.rpc.invoke.HttpInvoke;
import com.ibigsea.rpc.serizlize.JsonFormatter;
import com.ibigsea.rpc.serizlize.JsonParser;
import com.ibigsea.rpc.serizlize.Request;
/**
* 服务提供者代理
*
* @author bigsea
*
*/
public class ProviderProxyFactory extends AbstractHandler {
private Logger LOG = LoggerFactory.getLogger(ProviderProxyFactory.class);
/**
* 提供服务需要注册,这里使用map类实现简单的注册约定俗成的,暴漏服务是需要注册的
*/
private Map<Class, Object> providers = new ConcurrentHashMap<Class, Object>();
/**
* 这里用来获取暴露的服务
*/
private static ProviderProxyFactory factory;
private static HttpInvoke invoke = HttpInvoke.getInstance();
/**
* 构造方法注册服务创建http容器,并启动
*
* @param providers
* @param config
*/
public ProviderProxyFactory(Map<Class, Object> providers, ProviderConfig config) {
this.providers = providers;
HttpContainer container = new HttpContainer(this, config);
container.start();
factory = this;
for (Map.Entry<Class, Object> entry : providers.entrySet()) {
Log.info(entry.getKey().getSimpleName() + " register");
}
}
/**
* 处理请求服务消费者发送请求报文过来,服务提供者解析请求报文,通过反射执行方法
*/
public void handle(String target, HttpServletRequest request, HttpServletResponse response, int dispatch)
throws IOException, ServletException {
// 获取请求报文
String data = request.getParameter("data");
try {
// 反序列化
Request req = JsonParser.reqParse(data);
// 获取到注册的服务,并通过反射执行方法
Object res = req.invoke(ProviderProxyFactory.getInstance().getBeanByClass(req.getClazz()));
// 返回结果
invoke.response(JsonFormatter.resbFormatter(res), response.getOutputStream());
} catch (Exception e) {
e.printStackTrace();
} catch (RpcException e) {
e.printStackTrace();
}
}
public Object getBeanByClass(Class clazz) throws RpcException {
Object bean = providers.get(clazz);
if (bean != null) {
return bean;
}
throw new RpcException("service no register", new NullPointerException(), clazz);
}
public static ProviderProxyFactory getInstance() {
return factory;
}
}

对于服务消费者,我们通过jdk的invocationHandler来生成代理对象,对于生成的代理对象都会去执行invoke方法

ConsumerProxyFatory.java

[java] view plain copy

package com.ibigsea.rpc.proxy;
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;
import com.ibigsea.rpc.config.ConsumerConfig;
import com.ibigsea.rpc.invoke.HttpInvoke;
import com.ibigsea.rpc.serizlize.JsonFormatter;
import com.ibigsea.rpc.serizlize.JsonParser;
/**
* 服务消费者代理
*
* @author bigsea
*
*/
public class ConsumerProxyFactory implements InvocationHandler {
/**
* 消费者配置
*/
private ConsumerConfig config;
/**
* 需要通过远程调用的服务
*/
private String clazz;
private static HttpInvoke invoke = HttpInvoke.getInstance();
/**
* 创建一个动态代理对象,创建出来的动态代理对象会执行invoke方法
*
* @return
* @throws ClassNotFoundException
*/
public Object create() throws ClassNotFoundException {
Class interfaceClass = Class.forName(clazz);
return Proxy.newProxyInstance(interfaceClass.getClassLoader(), new Class[] { interfaceClass }, this);
}
/**
* 动态代理对象执行该方法获取(类信息,方法,参数)通过序列化封装成请求报文,通过http请求发送报文到服务提供者
*/
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
String resb = invoke.request(req, config);
// 解析响应报文
return JsonParser.resbParse(resb);
}
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

[java] view plain copy

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

[java] view plain copy

package com.ibigsea.vo;
import java.io.Serializable;
/**

* @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

我们可以启动程序看看

先启动服务提供者,服务提供者控制台

然后执行服务消费者的测试方法,服务消费者控制台:

服务提供者这里输出了消费者请求的日志

14:44:33.117 [[email protected] - /invoke] DEBUG org.mortbay.log - REQUEST /invoke on [email protected]
14:44:33.213 [[email protected] - /invoke] DEBUG org.mortbay.log - RESPONSE /invoke 200

演示成功

注意

因为这里使用了fastjson, 而我们的Request里面有类信息,进行序列化和反序列的时候我们要在启动类增加参数

-Dfastjson.parser.autoTypeSupport=true
