Hessian Introductory case

1.1. Hessian Introduction

Hessian:hessian is a lightweight remoting onhttp tool that provides RMI functionality in a simple way, simpler and faster than Webservice,hessian. The use of the binary RPC protocol, because the use of binary protocol, it is very suitable for sending binary data, Hessian mainly for object-oriented message communication.

1.2. Development step 1.2.1. Importing JAR Packages

Go to the official website to download http://hessian.caucho.com/

1.2.2. Writing a remote interface

Ihello.java

Package Cn.tempus.hessian; Public interface Ihello { Public String SayHello (string name); }

1.2.3. Writing a remote interface implementation class

Helloimpl.java need to inherit Hessianservlet

Package Cn.tempus.hessian; import Com.caucho.hessian.server.HessianServlet; Public class Helloimpl extends hessianservlet implements Ihello { private static final long serialversionuid =- 6448991611447150108L; Public String SayHello (string name) { return "Hello:"+name; } }

1.2.4 Configuring a servlet in a. web. xml file

Xml

<? XML version="1.0" encoding="UTF-8"?> < web-app  < Span style= "Color:rgb (127,0,127)" >xmlns:xsi = "http://www.w3.org/ 2001/xmlschema-instance " xmlns = " Http://java.sun.com/xml/ns/javaee " xsi: schemalocation = "Http://java.sun.com/xml/ns/javaee/http Java.sun.com/xml/ns/javaee/web-app_3_0.xsd "  id = "webapp_id"  version = "3.0" > < Display-name > Hessiandemo</display-name> < servlet > < Servlet-name > Hello</servlet-name> < Servlet-class >com.caucho.hessian.server.HessianServlet</servlet-class> < Init-param > < Param-name >home-class</param-name> < Param-value >cn.tempus.hessian.HelloImpl</param-value> </ Init-param > < Init-param > < Param-name >home-API</param-name> < Param-value >cn.tempus.hessian.IHello</param-value> </ Init-param > < Load-on-startup >1</load-on-startup> </ servlet > < servlet-mapping > < Servlet-name > Hello</servlet-name> < Url-pattern >/hello</url-pattern> </ servlet-mapping > </ Web-app >

1.2.5. Writing a client

Client.java

Package Cn.tempus.hessian; import java.net.MalformedURLException; import com.caucho.hessian.client.HessianProxyFactory; Public class Client { Public static String URL = "Http://127.0.0.1:8080/HessianDemo/Hello"; Public static void main (string[] args) { Hessianproxyfactory Factory = new hessianproxyfactory (); Try { Ihello Ihello = (Ihello) factory. Create (Ihello. Class, URL); System. out. println (Ihello. SayHello ("Morris")); } Catch (malformedurlexception e) { e. Printstacktrace (); } } }

1.2.6. Publish Project to Jetty

Jetty Background Printing

1.2.7. Running the client

The results are as follows:

Hello:morris
