简单Hessian实例

1.下载最新的Hessian的jar文件(我们用的是for java),地址为:http://hessian.caucho.com/

2.用eclipse新建一个web工程,命名为:WebTest;把第一步下载的jar文件放入该工程

3.新建一个接口和三个类,运行BasicClient类即可在控制台看到效果

 接口 IBasic :

 public interface IBasic {public String hello();public Car getCar();} 

 

   类 Car:

 import java.io.Serializable;public class Car implements Serializable{/** TODO */private static final long serialVersionUID = 1L;private String name;private String length;private String color;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getLength() {return length;}public void setLength(String length) {this.length = length;}public String getColor() {return color;}public void setColor(String color) {this.color = color;}} 

    类 BasicService :

 public class BasicService implements IBasic {public Car getCar() {Car c = new Car();c.setColor("红色");c.setLength("2m");c.setName("火车");return c;}private String hello = "Hello World";public String hello() {return hello;}} 

  类 BasicClient :

import java.net.MalformedURLException;import com.caucho.hessian.client.HessianProxyFactory;public class BasicClient {public static void main(String[] args){String url = "http://127.0.0.1:8081//WebTest/hello"; HessianProxyFactory factory = new HessianProxyFactory(); IBasic basic;try { basic = (IBasic) factory.create(IBasic.class, url); Car car = basic.getCar(); System.out.println("Hello: " + basic.hello()); System.out.println("color: " + car.getColor()); System.out.println("length: " + car.getLength()); System.out.println("name: " + car.getName());} catch (MalformedURLException e) {e.printStackTrace();} }} 

  web.xml文件改成如下:

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>WebTest</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <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>BasicService</param-value> </init-param> <init-param> <param-name>home-api</param-name> <param-value>IBasic</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>hello</servlet-name> <url-pattern>/hello</url-pattern> </servlet-mapping> </web-app>
