WebService的实现——Hessian

一、所需的jar包（http://download.csdn.net/detail/huangzebiao007/6379995）

二、Hessian实现步骤

1、创建一个普通的web项目，并导入jar包

2、创建服务器端接口和实现类

package com.hzb;
public interface Hello {
	public String sayHello(String name);
}

package com.hzb;

public class HelloImp implements Hello {

	public String sayHello(String name) {
		return name+":"+"hello world!";
	}

}

3、在web.xml文件中配置hessian，并将该项目部署到tomcat上

 	<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>com.hzb.HelloImp</param-value>    
            </init-param>    
            <init-param>    
                <param-name>home-api</param-name>    
                <param-value>com.hzb.Hello</param-value>    
            </init-param>    
        </servlet>         
   <!--下面是配置该接口对外提供的地址-->
        <servlet-mapping>    
            <servlet-name>hello</servlet-name>    
            <url-pattern>/hello</url-pattern>    
        </servlet-mapping> 

4、创建客户端项目（引入服务器项目或服务器端jar包）

package com.hzb.client;

import com.caucho.hessian.client.HessianProxyFactory;
import com.hzb.Hello;

public class HelloServiceTest {  
    
    public static void main(String[] args) throws Exception {  
        
       String url = "http://localhost:8080/Hessian/hello";  
     
       HessianProxyFactory factory = new HessianProxyFactory();  
       Hello hello = (Hello) factory.create(Hello.class,url);  
     
       System.out.println("远程调用结果: "+ hello.sayHello("hzb"));  
     
    }  
  }  

远程调用结果: hzb:hello world!
