Hessian 入门

    从网上看到Hessian,你可以不用考虑什么soap,也可以不用编写什么ejb,甚至比axis还要简单;关键是它支持java,flex,objectc,c++,ruby等几种常用的高级语言.
下载后做了个例子,现在分享给大家:

1.建立接口Ibase:

public interface Ibase {

	public String sayHello();
}

(Hessian也可以传送对象,对象必须序列化)

2.建立实现类BaseImpl:

public class BaseImpl implements Ibase {

	@Override
	public String sayHello() {
		// TODO Auto-generated method stub
		return "Hello World";
	}

}

3.配置xml文件:

<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>C.chapter.A.BaseImpl</param-value>
		</init-param>
		<init-param>
			<param-name>home-api</param-name>
			<param-value>C.chapter.A.Ibase</param-value>
		</init-param>
	</servlet>
	<servlet-mapping>
		<servlet-name>hello</servlet-name>
		<url-pattern>/hello</url-pattern>
	</servlet-mapping>

4.启动服务器,编写客户端:

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		String url="http://127.0.0.1:8080/dt/hello";
		HessianProxyFactory factory = new HessianProxyFactory ();
		try {
			Ibase base = (Ibase) factory.create(Ibase.class, url);
			System.out.println(base.sayHello());
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
		
	}

}

5.运行后得到结果:
"Hello World";



一切都是那么美好..
