关于二进制Web服务框架Hessian最简单代码实例

在resin3.1 下测试通过

hessian版本： hessian-3.1.6.jar

官方地址：

http://hessian.caucho.com/#Java

http://hessian.caucho.com/

步骤如下：

1. 接口定义

package com.yanek.study.hessian;

public interface Hello {

public String hello(String name);

}

2.接口实现

package com.yanek.study.hessian;

public class HelloImpl implements Hello {

public String hello(String name)
{

return "hello " + name + " welcome study Hessian";

}

}

3. web.xml配置

配置HessianServlet ，配置提供服务的类

<servlet>

<servlet-name>hessianService</servlet-name>

<servlet-class>com.caucho.hessian.server.HessianServlet</servlet-class>

<load-on-startup>1</load-on-startup>

<init-param>

<param-name>service-class</param-name>

<param-value>com.yanek.study.hessian.HelloImpl</param-value>

</init-param>

</servlet>

<servlet-mapping>
<servlet-name>hessianService</servlet-name>
<url-pattern>/hessianService</url-pattern>

</servlet-mapping>

4. 客户端测试类：

package com.yanek.study.hessian;

import java.net.MalformedURLException;

import com.caucho.hessian.client.HessianProxyFactory;

public class HessianClient {

/**
* @param args
*/
public static void main(String[] args) {

// Hessian服务的url

String url = "http://study.myweb.com/hessianService";

// 创建HessianProxyFactory实例

HessianProxyFactory factory = new HessianProxyFactory();

// 获得Hessian服务的远程引用

Hello d;
try {
d = (Hello) factory.create(Hello.class, url);
// 调用远程服务。

System.out.println("下面调用Hessian服务: " + d.hello("yanek"));
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}
