Hessian<初学例子>

    昨天发现有这样的好东西！研究了一下，发现很不错！介绍个大家学习学习，而且这个资料比较少，希望能让大家入门了！

定义一个接口

package study.hessian;

public interface IBasic {    
  
    public String hello();    
 
    public Person getPerson();    
   
}  

 一个接口的实现类

package study.hessian;
 
public class BasicService implements IBasic {    
  private String hello= "Hello, Vincent";    
   
  public String hello()    
  {    
    return hello;    
  }    
   
    public Person getPerson() {    
        Person person = new Person();    
        person.setColor("Yello");    
        person.setLength("176cm");    
        person.setName("vincent");    
        return person;    
    }    
}  

 定义一个实体，必须实现序列化接口，因为要通过网络传输

package study.hessian;

import java.io.Serializable;

public class Person implements Serializable{

	private static final long serialVersionUID = 3276641446246664L;
	private String name;
	private String length;
	private String color;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getLength() {
		return length;
	}

	public void setLength(String length) {
		this.length = length;
	}

	public String getColor() {
		return color;
	}

	public void setColor(String color) {
		this.color = color;
	}

}

 

web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	<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>study.hessian.BasicService</param-value>
		</init-param>
		<init-param>
			<param-name>home-api</param-name>
			<param-value>study.hessian.IBasic</param-value>
		</init-param>
	</servlet>

	<servlet-mapping>
		<servlet-name>hello</servlet-name>
		<url-pattern>/hello</url-pattern>
	</servlet-mapping>
</web-app>

 

客户端的类

package study.hessian;

import com.caucho.hessian.client.HessianProxyFactory;

public class BasicClient {    
    public static void main(String []args)    
        throws Exception    
      {    
        String url = "http://127.0.0.1:8080/WorkTest/hello";    
        HessianProxyFactory factory = new HessianProxyFactory();    
        IBasic basic = (IBasic) factory.create(IBasic.class, url);
        System.out.println(basic);
          Person person   = basic.getPerson();    
          System.out.println("Hello: " + basic.hello());    
        System.out.println("Hello: " + person.toString());    
      }    
} 

 String url = http://127.0.0.1:8080/WorkTest/hello;

WorkTest 工程名字

在http://hessian.caucho.com 下载一个 hessian.jar文件倒到工程就可以了！
