eclipse下用xfire開發web service

1、在eclipse下新建一個web工程,名爲:xfireDemo: html

2、導入XFire用戶庫。該庫中應包含xfire-1.26目錄下的xfire-all-1.2.6.jar文件,以及xfire-1.2.6\lib目錄下的全部文件。 java

3、修改項目下的web.xml文件爲: web

<?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映射代表,全部匹配「/services/*」的url請求所有交給org.codehaus.xfire.transport.http.XFireConfigurableServlet來處理。 spring

4、編寫須要發佈爲WebService的Java接口: apache

package com.yao.xfire.service;


public interface MathService {


public int add(int a,int b);
}
5、編寫實現其接口的類:
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;
	}

}
6、在WebContent\META-INF目錄下新建xfire文件夾,而後在xfire目錄下添加一個XFire使用的配置文件services.xml,該配置文件中的內容反映了要將哪些java類發佈爲web服務。本例中的services.xml內容以下:
<?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會藉助Spring來解析services.xml,從中提取須要發佈爲WebService的配置信息。
不少文章介紹到這裏就完了,然而當我按照他們所說的啓動WebService ,而後經過http://localhost:8080/XFireZhuweiTest/services/MathService?wsdl 來訪問服務描述時,卻拋出了異常,說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」。  app

7、很是關鍵的一點,在WebContent\WEB-INF目錄下新建classes文件夾,而後須要將WebContent下的整個META-INF文件夾剪切到新建的classes文件夾下。
到這裏,項目的完整目錄結構以下: eclipse

8、右鍵->Run As ->Run On Server,關聯到你機器上的Tomcat,而後會啓動Tomcat,以啓動web服務。 jsp

9、在IE中輸入 http://localhost:8080/xfireDemo/services/MathService?wsdl 會獲得正確的web服務描述文檔。 url

10、新建一個客戶端訪問類MathServiceClient: spa

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){
			//建立服務
			Service srvcModel = new ObjectServiceFactory().create(MathService.class);
			//建立XFire對象
			XFireProxyFactory factory = new XFireProxyFactory(XFireFactory.newInstance().getXFire());
			//調用Web服務
			mathService = (MathService) factory.create(srvcModel, serviceUrl);
			
			//設置客戶端調用的屬性
			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");
			//若是須要設置代理
			//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);
	}
}
將獲得結果:get the result: 15。
