Hessian实例(转)
试着写了一个Hessian的例子，是参考caucho官网上的一个example，很简单，也没什么实际的意义，但足以领会Hessian的用法。?
1、建立一个Remote Interface?
package com.hessian.test;public interface MathService {public int add(int a, int b);}?2、Service Implementation?
package com.hessian.test;import com.caucho.hessian.server.HessianServlet;public class HessianMathService extends HessianServlet implements MathService {public int add(int a, int b) {return a + b;}}?3、在web.xml 配置文件里加入servlet处理类来处理远程调用
<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><servlet><servlet-name>math</servlet-name><servlet-class>com.hessian.test.HessianMathService</servlet-class></servlet><servlet-mapping><servlet-name>math</servlet-name><url-pattern>/hessian/math</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>
?4、Java client?
import java.net.MalformedURLException;import com.caucho.hessian.client.HessianProxyFactory;import com.hessian.test.MathService;public class HessianClientTest {public static void main(String[] args) {String url = "http://localhost:8080/HessianServer/hessian/math";HessianProxyFactory factory = new HessianProxyFactory();MathService math = null;try {math = (MathService) factory.create(MathService.class, url);} catch (MalformedURLException e) {System.out.println("occur exception: " + e);}System.out.println("3 + 2 = " + math.add(3, 2));}}?
5 将服务端的接口打成jar包给client端引用，然后就可以运行client程序，看出hissian远程调用的结果了。
