Burlap开发学习
Burlap 简介
Burlap也是有caucho提供，它和hessian的不同在于，它是基于XML-RPC协议的。
1、是基于什么协议实现的？
基于XML-RPC协议实现。
2、怎么发起请求？
根据Burlap提供的API。
3、怎么将请求转化为符合协议的格式的？
将请求信息转化为符合协议的XML格式，转化为流进行传输。
4、使用什么传输协议传输？
Http协议。
5、响应端基于什么机制来接收请求？
监听Http请求。
6、怎么将流还原为传输格式的？
根据XML-RPC协议进行还原。
7、处理完毕后怎么回应？
返回结果写入XML中，由Burlap返回至调用端。
声明服务端接口：
package com.easyway.caucho.burlap.ws;
import java.util.List;
/**
* 声明服务端相关的服务
*
* @author longgangbai
*
*/
public interface BurlapService {
public String getUserName();
public List<String> getList();
public void setGreeting(String greeting);
public String hello();
}
实现服务端的服务代码示例如下：
package com.easyway.caucho.burlap.ws;
import java.util.ArrayList;
import java.util.List;
import com.caucho.burlap.server.BurlapServlet;
/**
*
* 在Burlap中服务端的必须继承BurlapServlet 类同时实现相关的服务的接口
*
* @author longgangbai
*
*/
public class BurlapWS extends BurlapServlet implements BurlapService {
private String _greeting = "Hello, world";
/**
*
*/
public void setGreeting(String greeting) {
_greeting = greeting;
}
/**
*
*/
public String hello() {
return _greeting;
}
/**
*
*/
public List<String> getList() {
List<String> strList = new ArrayList<String>();
strList.add("a");
strList.add("c");
strList.add("b");
strList.add("d");
strList.add("e");
strList.add("g");
strList.add("h");
strList.add("j");
strList.add("k");
strList.add("l");
strList.add("q");
return strList;
}
/**
*
*/
public String getUserName() {
return _greeting;
}
}
客户端访问代码如下：
package com.easyway.caucho.burlap.ws;
import java.net.MalformedURLException;
import com.caucho.burlap.client.BurlapProxyFactory;
/**
* Burlap客户端测试代码
*
* @author longgangbai
*
*/
public class BurlapServiceWSClient {
public static void main(String[] args) {
String url = "http://localhost:8080/BurlapWS/remoting/burlapWs";
BurlapProxyFactory factory = new BurlapProxyFactory();
BurlapService basic;
try {
basic = (BurlapService) factory.create(BurlapService.class, url);
System.out.println("hello(): " + basic.getUserName());
System.out.println("getList(): " + basic.getUserName());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
web.xml配置如下：
