一、在eclipse下新建一个web工程,名为:xfireDemo:
二、导入XFire用户库。该库中应包含xfire-1.26目录下的xfire-all-1.2.6.jar文件,以及xfire-1.2.6\lib目录下的所有文件。
三、修改项目下的web.xml文件为:
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>xfireDemo</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>xfireServlet</servlet-name> <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>xfireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> </web-app>
web.xml中添加的servlet映射表明,所有匹配“/services/*”的url请求全部交给org.codehaus.xfire.transport.http.XFireConfigurableServlet来处理。
四、编写需要发布为WebService的Java接口:
package com.yao.xfire.service; public interface MathService { public int add(int a,int b); }五、编写实现其接口的类:
package com.yao.xfire.service; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MathServiceImpl implements MathService { private final Log log = LogFactory.getLog(MathServiceImpl.class); public int add(int a, int b) { log.info("invoke method add."); return a + b; } }六、在WebContent\META-INF目录下新建xfire文件夹,然后在xfire目录下添加一个XFire使用的配置文件services.xml,该配置文件中的内容反映了要将哪些java类发布为web服务。本例中的services.xml内容如下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://xfire.codehaus.org/config/1.0"> <service> <name>MathService</name> <namespace>http://com.yao.xfire.service/MathService</namespace> <serviceClass>com.yao.xfire.service.MathService</serviceClass> <implementationClass>com.yao.xfire.service.MathServiceImpl</implementationClass> </service> </beans>
XFire会借助Spring来解析services.xml,从中提取需要发布为WebService的配置信息。
很多文章介绍到这里就完了,然而当我按照他们所说的启动WebService ,然后通过http://localhost:8080/XFireZhuweiTest/services/MathService?wsdl 来访问服务描述时,却抛出了异常,说services.xml文件不存在--
“org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [META-INF/xfire/services.xml]; nested exception is java.io.FileNotFoundException: class path resource [META-INF/xfire/services.xml] cannot be opened because it does not exist”。
七、非常关键的一点,在WebContent\WEB-INF目录下新建classes文件夹,然后需要将WebContent下的整个META-INF文件夹剪切到新建的classes文件夹下。
到这里,项目的完整目录结构如下:
八、右键->Run As ->Run On Server,关联到你机器上的Tomcat,然后会启动Tomcat,以启动web服务。
九、在IE中输入 http://localhost:8080/xfireDemo/services/MathService?wsdl 会得到正确的web服务描述文档。
十、新建一个客户端访问类MathServiceClient:
package com.yao.xfire.client; import java.net.MalformedURLException; import org.codehaus.xfire.XFireFactory; import org.codehaus.xfire.client.Client; import org.codehaus.xfire.client.XFireProxyFactory; import org.codehaus.xfire.service.Service; import org.codehaus.xfire.service.binding.ObjectServiceFactory; import org.codehaus.xfire.transport.http.CommonsHttpMessageSender; import com.yao.xfire.service.MathService; public class MathServiceClient { private static MathService mathService; private MathServiceClient(){} public static MathService getMathService(String serviceUrl) throws MalformedURLException{ if(mathService == null){ //创建服务 Service srvcModel = new ObjectServiceFactory().create(MathService.class); //创建XFire对象 XFireProxyFactory factory = new XFireProxyFactory(XFireFactory.newInstance().getXFire()); //调用Web服务 mathService = (MathService) factory.create(srvcModel, serviceUrl); //设置客户端调用的属性 Client client = Client.getInstance(mathService); client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "300"); client.setProperty(CommonsHttpMessageSender.DISABLE_KEEP_ALIVE, "true"); client.setProperty(CommonsHttpMessageSender.DISABLE_EXPECT_CONTINUE, "true"); //如果需要设置代理 //client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_HOST, "10.3.1.6" ); //client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_PORT, "8080"); } return mathService; } public static void main(String[] args) throws MalformedURLException{ MathService service = MathServiceClient.getMathService("http://localhost:8080/xfireDemo/services/MathService"); int result = service.add(1, 14); System.out.println("get the result: " + result); } }将得到结果:get the result: 15。
