用xfire开发webservice实例(原稿)

                     用xfire开发webservice总结
本实例是以简单的加减法（a+b和a-b）运算实现用xfire开发webservice服务端和客户端。
一、开发环境
运行环境： Tomcat 6.0.14,jdk 1.5
开发工具：Eclipse3.2 + MyEclipse 5.5
二、开发service(服务端)
开发之前请先到官方(http://xfire.codehaus.org/Download)下载xfire-distribution-1.2.6.zip并解压缩.
1.在MyEclipse 建立一个web工程，命名为：XFireWebService,在src目录下新建一个META-INF文件夹里包含xfire/service.xml，把xfire-1.2.6里lib所有jar和xfire-all-1.2.6.jar拷贝到工程lib里，工程具体信息如附件图

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.写MathService接口类和MathServicImpl实现类
MathService接口类
package com.test.ws;

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

MathServiceImpl实现类
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会自动编译src文件，请到MyEclipse的workspace里找到刚才建的XFireWebService工程，打开工程并copy WebRoot文件夹到%TOMCAT_HOME%/webapps里并把WebRoot改名为xfire，参照图如附件：

三、开发client(客户端)
开发client有几种模式
1． 纯POJO模式
需要service端提供MathService接口类
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端开发组需要向Client提供MathService的实现类MathServiceImpl，而不止于接口，有点危险,不提倡用这个模式。暂不研究。

3． SpringSide
暂空着，下轮用到再详解。
4． 动态模式
动态模式不需要服务端的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． 根据WSDL生成Client Stub
创建client文件夹里含build.xml文件，内容如下
<?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打开至client文件夹，执行ant.
在所生成的client工程里写一个含math方法的ClientTest类
四、启动Tomcat, 测试
运行客户端程序即可看到结果。
Good luck to you!

例子怎么没有用两个工程做示例啊。。。。
