**XFire创建WebService实例应用**

XFire使得在JavaEE应用中发布Web服务变得轻而易举。和其他Web服务引擎相比，  
XFire的配置非常简单，可以非常容易地和Spring集成。  
下载地址：[http://xfire.codehaus.org/Download][http_xfire.codehaus.org_Download]。

**一． 使用XFire发布WebService**

**1. 创建service接口**

Java代码 ![收藏代码][icon_star.png]

1.  **package** com.test.service; 
2.  **import** com.test.service.bean.User; 
3.  
4.  **public** **interface** IHelloService \{ 
5.  **public** String sayHello(String name); 
6.  **public** User getUser(User user); 
7.   \} 
8.  \}

**2.创建Service接口的实现类**

Java代码 ![收藏代码][icon_star.png]

1.  **package** com.test.service; 
2.  **import** com.test.service.bean.User; 
3.  **public** **class** HelloService **implements** IHelloService\{ 
4.  **public** String sayHello(String name)\{ 
5.  **return** "Hello, "\+name; 
6.   \} 
7.  **public** User getUser(User user) \{ 
8.   User userNew = **new** User(); 
9.   userNew.setId("new:"\+user.getId()); 
10.  userNew.setName("new:"\+user.getName()); 
11. **return** userNew; 
12.  \} 
13. \}

1.  **package** com.test.service.bean; 
2.  **public** **class** User \{ 
3.  **private** String id; 
4.  **private** String name; 
5.  **public** String getId() \{ 
6.  **return** id; 
7.   \} 
8.  **public** **void** setId(String id) \{ 
9.  **this**.id = id; 
10.  \} 
11. **public** String getName() \{ 
12. **return** name; 
13.  \} 
14. **public** **void** setName(String name) \{ 
15. **this**.name = name; 
16.  \} 
17. \}

**3.在web.xml文件中进行XFire拦截配置，可参照官网提供的sample。**

Xml代码 ![收藏代码][icon_star.png]

1.  **<?****xml** version="1.0" encoding="UTF-8"**?>**
2.  **<****web-app** version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
3.  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4.  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
5.   http://java.sun.com/xml/ns/j2ee/web-app\_2\_4.xsd"**>**
6.  
7.  **<****servlet****>**
8.  **<****servlet-name****>**XFireServlet**</****servlet-name****>**
9.  **<****servlet-class****>**
10.  org.codehaus.xfire.transport.http.XFireConfigurableServlet 
11. **</****servlet-class****>**
12. **</****servlet****>**
13. **<****servlet-mapping****>**
14. **<****servlet-name****>**XFireServlet**</****servlet-name****>**
15. **<****url-pattern****>**/servlet/XFireServlet/\***</****url-pattern****>**
16. **</****servlet-mapping****>**
17. **<****servlet-mapping****>**
18. **<****servlet-name****>**XFireServlet**</****servlet-name****>**
19. **<****url-pattern****>**/services/\***</****url-pattern****>**
20. **</****servlet-mapping****>**
21. **</****web-app****>**

**4.在class目录下建立META-INF目录,如（META-INF>xifre->services.xml）,  
在services.xml文件中进行webservice服务的发布，可参照官网提供的sample。**

Xml代码 ![收藏代码][icon_star.png]

1.  **<?****xml** version="1.0" encoding="UTF-8"**?>**
2.  **<****beans** xmlns="http://xfire.codehaus.org/config/1.0"**>**
3.  **<****service****>**
4.  **<****name****>**HelloService**</****name****>**
5.  **<****serviceClass****>**com.test.service.IHelloService**</****serviceClass****>**
6.  **<****implementationClass****>**com.test.service.HelloService**</****implementationClass****>**
7.  **</****service****>**
8.  **</****beans****>**

**5.将xfire的Jar包和相关依赖包拷到系统应用中，在Tomcat下部署应用。**  
 启动tomcat后访问服务（需在应用后加上/services,webservice才会进行拦截）：  
例：[http://localhost:8080/ws2/services][http_localhost_8080_ws2_services]。(IE下有时无法显示列表，可用其它浏览器显示或指定接口名称）  
界面如下：

点击后查看详细的wsdl文档，不同的浏览器下访问会有区别，展示效果不一致。

**二．建立XFire客户端进行调用**

**1.本地客户端调用，与webservice服务在同一应用。**

Java代码 ![收藏代码][icon_star.png]

1.  **package** com.test.client; 
2.  
3.  **import** java.net.MalformedURLException; 
4.  **import** org.codehaus.xfire.XFireFactory; 
5.  **import** org.codehaus.xfire.client.XFireProxyFactory; 
6.  **import** org.codehaus.xfire.service.Service; 
7.  **import** org.codehaus.xfire.service.binding.ObjectServiceFactory; 
8.  **import** com.test.service.IHelloService; 
9.  **import** com.test.service.bean.User; 
10. 
11. **public** **class** ClientTest \{ 
12. **public** **static** **void** main(String args\[\]) **throws** MalformedURLException \{ 
13.  Service service = **new** ObjectServiceFactory().create(IHelloService.**class**); 
14.  XFireProxyFactory factory = **new** XFireProxyFactory(XFireFactory 
15.  .newInstance().getXFire()); 
16.  String url = "http://localhost:8080/ws2/services/HelloService"; 
17.  IHelloService helloService = (IHelloService) factory.create(service,url); 
18.  System.out.println(helloService.sayHello("张三")); 
19.  User user = **new** User(); 
20.  user.setName("张三"); 
21.  System.out.println(helloService.getUser(user).getName()); 
22.  \} 
23. \}

执行结果如下：

Java代码 ![收藏代码][icon_star.png]

1.  Hello, 张三 
2.  **new**:张三

**2. 利用XFire创建build.xml文件生成客户端代码调用webservice服务**

**2.1在src目录下创建build.properties文件，配置如下：**

Java代码 ![收藏代码][icon_star.png]

1.  src.dir=$\{basedir\} 
2.  lib.dir=D:/myspace/ws2/WebRoot/WEB-INF/lib 
3.  wsdl.dir=http\\://localhost\\:8080/ws2/services/HelloService?wsdl

**2.2在src目录下创建build.xml文件，配置如下：**

Xml代码 ![收藏代码][icon_star.png]

1.  **<?****xml** version="1.0" encoding="UTF-8"**?>**
2.  **<****project** name="WebService" basedir="." default="gen-webservice"**>**
3.  **<****property** file="build.properties"**>****</****property****>**
4.  **<****path** id="project-classpath"**>**
5.  **<****fileset** dir="$\{lib.dir\}"**>**
6.  **<****include** name="\*\*/\*.jar" **/>**
7.  **</****fileset****>**
8.  **</****path****>**
9.  
10. **<****target** name="gen-webservice"**>**
11. **<****taskdef** name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask"
12. classpathref="project-classpath" **/>**
13. **<****wsgen** outputDirectory="$\{src.dir\}" wsdl="$\{wsdl.dir\}"
14. package="stub.test.client" overwrite="true"**/>**
15. **</****target****>**
16. **</****project****>**

用ant构建生成代码，生成后的目录如下：

**2.3编写客户端代码进行调用**

Java代码 ![收藏代码][icon_star.png]

1.  **package** com.test.client; 
2.  **import** stub.test.client.HelloServiceClient; 
3.  **import** stub.test.client.HelloServicePortType; 
4.  **import** com.test.service.bean.ObjectFactory; 
5.  **import** com.test.service.bean.User; 
6.  
7.  **public** **class** HelloServiceTest \{ 
8.  
9.  **public** **static** **void** main(String args\[\])\{ 
10.  HelloServiceClient service = **new** HelloServiceClient(); 
11.  HelloServicePortType portType = service.getHelloServiceHttpPort(); 
12.  System.out.println(portType.sayHello("张三")); 
13. 
14.  ObjectFactory factory = **new** ObjectFactory(); 
15.  User user = factory.createUser(); 
16.  user.setName(factory.createUserName("张三")); 
17.  System.out.println(portType.getUser(user).getName().getValue()); 
18.  \} 
19. \}

执行结果如下：

1.  Hello, 张三 
2.  **new**:张三
