hessian+spring集成应用

注意事项

▲JAVA服务器端必须具备以下几点：
---->包含Hessian的jar包
---->设计一个接口，用来给客户端调用
---->实现该接口的功能
---->配置web.xml，配好相应的servlet
---->对象必须实现Serializable 接口
---->对于复杂对象可以使用Map的方法传递

▲客户端必须具备以下几点：
---->java客户端包含Hessian.jar的包。C#中引用hessianCSharp.dll
---->具有和服务器端结构一样的接口。包括命名空间都最好一样
---->利用HessianProxyFactory调用远程接口。
服务器端（向外暴漏接口的应用）

【2】客户端需要配置的spring-hessianclient.xml

 3         <!-- 客户端Hessian代理工厂Bean -->

【3】客户端业务类中的远程调用接口

 1 /**

 3      */
 4     public void testHessian() {
 5         // TODO Auto-generated method stub
 6         //从applicationContext容器中获取hessianfacttory
 7         OrderService orderService=(OrderService) context.getBean("hessianFactory");
 8         
 9         Date aDate=new Date();
10         //调用远程方法
11         orderService.sayHello("sxf", 25,aDate);
12         Order order=new Order();
13         order.setOrderNum(1234);
14         order.setCompanyName("易宝");
15         order.setPersonName("尚晓飞");
16         order.setOrderTime(aDate);
17         //调用远程方法
18         orderService.addOrder(order);
19         System.out.println("AuthorServiceImpl.testHessian()");
20         
21     }

【4】也可以通过另一种方式调用远程方法。

 1 public static void main(String[] args) throws MalformedURLException {
 2         //远程调用路径
 3         String url = "http://localhost:8081/paymoney-hessian/hessian/hessianOrder";
 4         //hessianproxyFactory的工厂对象。
 5         HessianProxyFactory factory = new HessianProxyFactory();
 6         //获取远程调用的接口代理对象
 7         OrderService orderService = (OrderService) factory.create(OrderService.class, url);
 8         
 9         Date gDate=new Date();
10         //调用远程方法
11         orderService.sayHello("123", 25,gDate);
12         
13         Order order=new Order();
14         order.setOrderNum(5201314);
15         order.setCompanyName("天天向上");
16         order.setOrderTime(gDate);
17         order.setPersonName("尚晓飞");
18         //调用远程方法
19         orderService.addOrder(order);
20        
21     }
