Hessian入门

     官方http://hessian.caucho.com/对hessian的描述很精辟:

     The Hessian binary web service protocol makes web services usable without requiring a large framework, and without learning yet another alphabet soup of protocols. Because it is a binary protocol, it is well-suited to sending binary data without any need to extend the protocol with attachments.

    只是怎么官方最近的jar to java貌似都不能用，鄙视下...

   

    Creating a Hessian service using Java has four steps:

1. Create an Java interface as the public API
2. Create a client using HessianProxyFactory
3. Create the Service implementation class
4. Configure the service in your servlet engine.

   public interface Hello {public String hello(String name);public Car getCar();}

   public class HelloImpl implements Hello {public String hello(String name) {return "hello " + name + ", you are very handsome!"; }public Car getCar() {Car car = new Car();car.setName("丰田卡罗拉");car.setColor("黑色");car.setLength("三米六");return car;}}

   public class Car implements Serializable {/** * */private static final long serialVersionUID = 1L;public String name;public String length;public String color; //getter setter省略}

   <servlet> <servlet-name>hessianService</servlet-name> <servlet-class>com.caucho.hessian.server.HessianServlet</servlet-class> <init-param> <param-name>home-class</param-name> <param-value>包名.HelloImpl</param-value> </init-param> <init-param> <param-name>home-api</param-name> <param-value>包名.Hello</param-value> </init-param></servlet> <servlet-mapping> <servlet-name>hessianService</servlet-name> <url-pattern>/hs</url-pattern> </servlet-mapping>

   public static void main(String[] args) throws Exception {String url = "http://localhost:8081/hessian/hs";HessianProxyFactory factory = new HessianProxyFactory();Hello d = (Hello) factory.create(Hello.class, url);System.out.println(d.hello("Allen"));System.out.println("his car:"+ d.getCar().getName());System.out.println("car color:"+ d.getCar().getColor());System.out.println("car length:"+ d.getCar().getLength());}
