【RPC框架Burlap】Spring集成Burlap
编程技术 / houtizong 发布于 3年前 73
- 基于HTTP协议
- 简单易上手，不需要定义复杂的接口描述文件，如WSDL，IDL
- 在RPC框架中，性能优越
- Spring对它们一致的集成，使得在Burlap和Hessian之间切换很容易，只要修改Spring的暴露接口(Exporter)和远程服务代理工厂类，就可以实现切换
- Burlap基于XML，Hessian基于二进制，这使得Burlap传输数据的可读性优于Hessian
- Hessian的性能稍微优于Burlap
Burlap和Hessian同属于codehaus的RPC调用框架，但是Burlap已经几年不更新，所以Spring在4.0里已经将Burlap的支持置为Deprecated,所以在选择RPC框架时，不应该考虑Burlap了。
这篇文章还是记录下Burlap的用法吧，主要是复制粘贴了Hessian与Spring集成一文，【RPC框架Hessian四】Hessian与Spring集成
Burlap和Hessian的共同点：
Burlap和Hessian的不同点：
在【RPC框架Hessian二】Hessian 对象序列化和反序列化一文中介绍了基于Hessian的RPC服务的实现步骤，在那里使用Hessian提供的API完成基于Hessian的RPC服务开发和客户端调用，本文使用Spring对Hessian的集成来实现Hessian的RPC调用。
定义模型、接口和服务器端代码
|---Model
|--ComplexModel
|--Person
|--Point
|---Interface
|--IComplexModelService
|---Service Implementation
|--ComplexModelService
定义pom.xml
添加对Spring、Hessian和Spring Remoting的支持

定义web.xml

定义客户端测试代码
package com.tom.hessian.client;import com.tom.hessian.common.ComplexModel;import com.tom.hessian.common.IComplexModelService;import com.tom.hessian.common.Person;import com.tom.hessian.common.Point;import org.springframework.context.support.ClassPathXmlApplicationContext;import java.util.ArrayList;import java.util.Date;import java.util.List;public class ComplextModelServiceSpringTest { public static void main(String[] args) throws Exception { ComplexModel<Point> model = new ComplexModel<Point>(); model.setId(1); Person person = new Person(); person.setName("Tom"); person.setAge(86); person.setBirthDay(new Date()); person.setSensitiveInformation("This should be private over the wire"); model.setPerson(person); List<Point> points = new ArrayList<Point>(); Point point = new Point(); point.setX(3); point.setY(4); points.add(point); point = new Point(); point.setX(100); point.setY(100); points.add(point); model.setPoints(points); //远程方法调用 ClassPathXmlApplicationContext cxt = new ClassPathXmlApplicationContext("applicationContext-hessian-client.xml"); IComplexModelService service = cxt.getBean("complexModelService", IComplexModelService.class); service.save(model); model = service.read(model.getId()); List<Point> points1 = model.getPoints(); for(Point elem : points1) { System.out.println(elem.getX() + "\t" + elem.getY()); } }}
运行
启动Jetty Server，然后运行上面的客户端代码，可以正常执行
