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();
  }

 }

}
