介紹:面向服務架構(SOA，Services-oriented architecture)和Web Services已經變成了當前行業的熱點話題。XFire正是在這種情況下產生的。它能夠使POJO發布為最少的Web Services，而只需要付出最小化的努力。從而，它使希望使用這項技術的初級開發者的學習曲線變得平緩。同時，由于它兼容最新標準和提供了豐富的API，XFire為高級用戶提供了更多的大好機會。步驟清單: 1、 檢查Java類的方法和默認構造函數確保為public

　 2、 增加XFire servlet相關條目到web.xml中

　 3、 創建services.xml，把它放到WEB-INF/classes/META-INF/xfire目錄下

　 4、 增加XFire和第三方包到你的Web應用的WEB-INF/lib文件夾中

實際例子: 0. 定義 web.xml<servlet><servlet-name>XFireServlet</servlet-name><display-name>XFire Servlet</display-name><servlet-class>org.codehaus.xfire.transport.http.XfireConfigurableServlet</servlet-class></servlet><servlet-mapping><servlet-name>XFireServlet</servlet-name><url-pattern>/servlet/XFireServlet/*</url-pattern></servlet-mapping> <servlet-mapping><servlet-name>XFireServlet</servlet-name><url-pattern>/services/*</url-pattern></servlet-mapping>

定義接口

public interface IBankingService { public String transferFunds(String fromAccount, String toAccount, double amount, String currency);}

2.定義實現

import java.text.NumberFormat; import java.text.DecimalFormat;/** XFire WebServices sample implementation class. */ public class BankingService implements IBankingService {//Default constructor.public BankingService(){ }/** Transfers fund from one account to another.*/public String transferFunds(String fromAccount, String toAccount, double amount, String currency){String statusMessage = "";//Call business objects and other components to get the job done.//Then create a status message and return.try {NumberFormat formatter = new DecimalFormat("###,###,###,###.00"); statusMessage = "COMPLETED: " + currency + " " + formatter.format(amount)+ " was successfully transferred from A/C# " + fromAccount + " to A/C# " + toAccount;} catch (Exception e){statusMessage = "BankingService.transferFunds(): EXCEPTION: " + e.toString();}return statusMessage;}}

3 定義 web 描述

<beans xmlns="http://xfire.codehaus.org/config/1.0"><service><name>Banking</name><namespace>mybank</namespace><serviceClass>com.mybank.xfire.example.IBankingService</serviceClass><implementationClass>com.mybank.xfire.example.BankingService</implementationClass></service> </beans>

4.部署獲得WSDL

WSDL的URL應該是:http://localhost:8080/websvc/services/Banking?wsdl。

5, 開發客戶端

//Create a metadata of the service Service serviceModel = new ObjectServiceFactory().create(IBankingService.class); log.debug("callSoapServiceLocal(): got service model." );//Create a proxy for the deployed serviceXFire xfire = XFireFactory.newInstance().getXFire();XFireProxyFactory factory = new XFireProxyFactory(xfire); String serviceUrl = "http://localhost:8080/websvc/services/Banking";IBankingService client = null;try {client = (IBankingService) factory.create(serviceModel, serviceUrl);} catch (MalformedURLException e) {log.error("WsClient.callWebService(): EXCEPTION: " + e.toString());} //Invoke the serviceString serviceResponse = "";try { serviceResponse = client.transferFunds(fromAccount, toAccount, amount, currency);} catch (Exception e){log.error("WsClient.callWebService(): EXCEPTION: " + e.toString()); serviceResponse = e.toString();}
