?????? 用xfire開發webservice總結
本實例是以簡單的加減法（a+b和a-b）運算實現用xfire開發webservice服務端和客戶端。
一、開發環境
運行環境： Tomcat 6.0.14,jdk 1.5
開發工具：Eclipse3.2 + MyEclipse 5.5
二、開發service(服務端)
開發之前請先到官方(http://xfire.codehaus.org/Download)下載xfire-distribution-1.2.6.zip并解壓縮.
1.在MyEclipse 建立一個web工程，命名為：XFireWebService,在src目錄下新建一個META-INF文件夾里包含xfire/service.xml，把xfire-1.2.6里lib所有jar和xfire-all-1.2.6.jar拷貝到工程lib里，工程具體信息如附件圖

2.修改WebRoot/Web-INF/web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app>
<welcome-file-list>
? <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

? <context-param>
???? <param-name>log4jConfigLocation</param-name>
???? <param-value>/WEB-INF/log4j.properties</param-value>
? </context-param>

<servlet>
? <servlet-name>XFireServlet</servlet-name>
? <servlet-class>
?? org.codehaus.xfire.transport.http.XFireConfigurableServlet
? </servlet-class>
? <load-on-startup>0</load-on-startup>
</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>
</web-app>

3.修改src/META-INF/xfire/services.xml文件
<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
? <name>MathService</name>
? <namespace>
?? http://localhost:8080/XFireWebService/MathService
? </namespace>
? <serviceClass>com.test.ws.MathServiceImpl</serviceClass>
</service>
</beans>

4.寫MathService接口類和MathServicImpl實現類
MathService接口類
package com.test.ws;

public interface? MathService {
public long add(int p1, int p2);
public long minus(int p3, int p4);
}

MathServiceImpl實現類
package com.test.ws;

public class MathServiceImpl implements? MathService{

public long add(int p1, int p2) {
System.out.println(p1 + p2);
???? return p1 + p2;
}

public long minus(int p3, int p4) {
System.out.println(p3 - p4);
return p3 - p4;
}
}

5.MyEclipse會自動編譯src文件，請到MyEclipse的workspace里找到剛才建的XFireWebService工程，打開工程并copy WebRoot文件夾到%TOMCAT_HOME%/webapps里并把WebRoot改名為xfire，參照圖如附件：

三、開發client(客戶端)
開發client有幾種模式
1． 純POJO模式
需要service端提供MathService接口類
package com.test.client;

import java.net.MalformedURLException;

import org.codehaus.xfire.XFire;
import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;

import com.test.ws.MathService;

public class CallXfireWebService_POJO {

/**
* @param args
*/
public static void main(String[] args) {
Service serviceModel = new ObjectServiceFactory().create(MathService.class);

XFire xfire = XFireFactory.newInstance().getXFire();?
XFireProxyFactory factory = new XFireProxyFactory(xfire);
String serviceUrl = "http://localhost:8080/xfire/services/MathService";

int p1 = 115;
int p2 = 4;

int p3 = 9;
int p4 = 240;

MathService client = null;
try {
client = (MathService) factory.create(serviceModel, serviceUrl);
} catch (MalformedURLException e) {
System.out.println( "Client call webservice has exception: " + e.toString());
}

int result1 = (int) client.add(p1, p2);
int result2 = (int) client.minus(p3, p4);
System.out.println(result1);
System.out.println(result2);

}
}

2． JSR181模式
Server端開發組需要向Client提供MathService的實現類MathServiceImpl，而不止于接口，有點危險,不提倡用這個模式。暫不研究。

3． SpringSide
暫空著，下輪用到再詳解。
4． 動態模式
動態模式不需要服務端的class,但在性能上有所欠佳。
package com.test.client;

import java.net.MalformedURLException;
import java.net.URL;

import org.codehaus.xfire.client.Client;

public class DynamicXfireWebService {

/**
* @param args
*/
public static void main(String[] args) {
Client client = null;
try {
client = new Client(new URL("http://localhost:8080/xfire/services/MathService?wsdl"));
Object[] result1 = client.invoke("add", new Object[] {1, 2});
Object[] result2 = client.invoke("minus", new Object[] {1, 2});

System.out.println(result1[0]);
System.out.println(result2[1]);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}

}

}

5． 根據WSDL生成Client Stub
創建client文件夾里含build.xml文件，內容如下
<?xml version="1.0"?>
<project default="genfiles" basedir=".">
??? <property name="lib" value="WebRoot/WEB-INF/lib" />
??? <path id="myclasspath">
??????? <fileset dir="${lib}">
??????????? <include name="*.jar" />
??????? </fileset>
??????? <pathelement location="${genfiles}" />
??? </path>
??? <property name="code_path" value="src" />
??? <property name="wsdl_path" value="http://localhost:8080/xfire/MathService?wsdl" />
??? <property name="code_package" value="com.playphone.ws.client" />
??? <target name="genfiles" description="Generate the files">
??????? <taskdef name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask" classpathref="myclasspath" />
??????? <wsgen outputDirectory="${code_path}" wsdl="${wsdl_path}" package="${code_package}" binding="xmlbeans" overwrite="true" />
??? </target>
</project>
用ms dos打開至client文件夾，執行ant.
在所生成的client工程里寫一個含math方法的ClientTest類
四、啟動Tomcat, 測試
運行客戶端程序即可看到結果。
Good luck to you!
