Hessian入门

一：服务端(HessianServlet暴露服务)

web.xml
	<servlet>
		<servlet-name>helloworld</servlet-name>
		<servlet-class>com.caucho.hessian.server.HessianServlet</servlet-class>
		<!-- 一个服务对应一个HessianServlet ？  -->
		<init-param>
			<param-name>home-class</param-name>
			<param-value>com.xx.service.impl.DefaultSayHelloServiceImpl</param-value>
		</init-param>
		
		<init-param>
			<param-name>home-api</param-name>
			<param-value>com.xx.service.ISayHelloService</param-value>
		</init-param>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>helloworld</servlet-name>
		<url-pattern>/helloworld.h</url-pattern>
	</servlet-mapping>

package com.xx.service;

public interface ISayHelloService {

	/**
	 * @param name
	 * @return
	 */
	 String doSayHello(String name);
}

package com.xx.service.impl;

import com.xx.service.ISayHelloService;

public class DefaultSayHelloServiceImpl implements ISayHelloService {

	public String doSayHello(String name) {
		return "hello, " + name;
	}
}

二：客户端

		String urlName = "http://localhost:8080/hessian_01/helloworld.h";
		HessianProxyFactory hessianProxyFactory = new HessianProxyFactory();
		ISayHelloService isHelloService = (ISayHelloService) hessianProxyFactory.create(ISayHelloService.class, urlName);
		System.out.println(isHelloService.doSayHello("李四 "));
