Tips: This hex-based communication program, and other online, or what you know at the moment is not the same thing, puzzled to see the code;

Summary:Xxl-hex is a lightweight remoting onhttp tool that provides RPC functionality using a simple method. The use of the 16 encoding protocol, has the following features: 1, data encryption, 2, cross-language;

cross-language, data transfer Scenarios :

JSON: A lightweight data Interchange format that is completely independent of the language (Bean object) JSON string;

XML: Extensible Markup Language, designed to transmit data (Bean object) XML string;

Xxl-hex (This scenario): A Hex data transfer scheme (Bean object) that requires a predetermined rule (hex string);

Communication Solutions :HttpClient + Servlet

Before designing the Xxl-hex, the optional communication scheme was Netty, MINA, jetty and so on (refer to my other wheel: http://www.cnblogs.com/xuxueli/p/4845111.html), but for the sake of kiss, Use the Httpclient+servlet method that is most convenient for system integration;

implementation principle, part of the logic point introduction :

1, the total call logic is: client-side package Irequest encoded as Hex post to the server side, server-side decoding after matching handler execution handle logic after the Iresponse response to the client side, after the client received, One request to finish.

2, IREQUEST message structure: Irequest message header holds the classname of the message, the server can instantiate irequest based on classname reflection, and match handler to execute handle logic;

3, irequest matching handler: Server maintenance a message hash table, according to the request message classname can be located to the processing handler, for example: Handlermap.put (" Com.xxl.demo.msg.request.DemoRequest "," Com.xxl.service.impl.DemoHandler ");

4. Server-Side Registration handler: The business handler must be a subclass of Ihandler and needs to be initialized when it is started (can be done by declaring a service for spring), Super.registry is called in the parameterless construct ( Xrequest.class); Can complete the relationship with Xrequest;

Use the tutorial :

1, the introduction of dependency (self-hit jar package, if necessary to provide jar package, can give me mail):

<dependency> <groupId>com.xxl</groupId> <artifactId>xxl-hex-core</artifactId> < Version>0.0.1-snapshot</version></dependency>

2. API development: Request, Response

Package Com.xxl.demo.msg.request;import Com.xxl.hex.core.codec.impl.irequest;public Class Demorequest extends irequest {private String Param;public string GetParam () {return param;} public void SetParam (String param) {this.param = param;}}

　　

Package Com.xxl.demo.msg.response;import Com.xxl.hex.core.codec.impl.iresponse;public Class DemoResponse extends Iresponse {private String Result;public string GetResult () {return result;} public void Setresult (String result) {This.result = result;}}

3. Server-Side development:

Configuration Hexservlet:

<servlet><servlet-name>hexServlet</servlet-name><servlet-class> com.xxl.hex.http.servlet.hexservlet</servlet-class></servlet><servlet-mapping>< servlet-name>hexservlet</servlet-name><url-pattern>/hexservlet</url-pattern></ Servlet-mapping>

Development handle:

Package Com.xxl.service.impl;import Org.springframework.stereotype.service;import Com.xxl.demo.msg.request.demorequest;import Com.xxl.demo.msg.response.demoresponse;import Com.xxl.hex.core.codec.impl.irequest;import Com.xxl.hex.core.codec.impl.iresponse;import Com.xxl.hex.core.handler.IHandler, @Servicepublic class Demohandler extends Ihandler{public Demohandler () { Super.registry (Demorequest.class);} @Overridepublic Iresponse handle (irequest request) {demorequest msg = (demorequest) request;demoresponse res = new Demores Ponse (Res.setcode); Res.setmsg ("Success"); Res.setresult ("Hi, Jack. ("+ msg.getparam () +") "); return res;}}

4. Client side:

Demorequest request = new Demorequest (); Request.setparam ("Hi, Lucy."); String Request_hex = Bytehexconverter.byte2hex (Request.tohexbyte ()); System.out.println (Request_hex); String url = "Http://localhost:8080/xxl-hex-demo-server/hexServlet"; String Response_hex = Httputil.sendhex (URL, request_hex); System.out.println (Response_hex);D emoresponse msg = (demoresponse) DemoResponse.class.newInstance (). Fillhexbyte ( Bytehexconverter.hex2byte (Response_hex)); System.out.println (Beanutils.describe (msg));

　　

Run:

Server side: Registering handler

Client side: Request log, log request data string;
