XFire WebService开发快速起步
?
环境:
XFire-1.2.6
JDK1.5
MyEclipse 6.5
Tomcat-5.5.27
Windows XP Professional简体中文版
?
软件下载地址:
[url]http://repository.codehaus.org/org/codehaus/xfire/xfire-distribution/1.2.6/xfire-distribution-1.2.6.zip[/url]
[url]http://apache.mirror.phpchina.com/tomcat/tomcat-5/v5.5.27/bin/apache-tomcat-5.5.27.zip[/url]
?
有关WebService的概念、原理、数据发现、描述、绑定等过程、方式也不说了。这里就只关注如何快速开发出来一个通用的、易懂的Hello World例子。
?
以下是开发步骤:
?
1、创建工程
?
打开MyEclipse 6.5,新建一个WebService工程。如下图

?

?
然后一路next,直到完成。
?
创建完成后,打开生成的web.xml文件,可以看到,XFire已经配置好了。
<? xml version ="1.0" encoding ="UTF-8" ?>
< web-app xmlns ="http://java.sun.com/xml/ns/javaee" xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance" version ="2.5" xsi:schemaLocation ="http://java.sun.com/xml/ns/javaee???? [url]http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd[/url]" >
???? < 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 >/services/* </ url-pattern >
???? </ servlet-mapping >
???? < welcome-file-list >
???????? < welcome-file >index.jsp </ welcome-file >
???? </ welcome-file-list >
</ web-app >
?
2、创建WebService服务
?
创建两个个包“wstest.server”和“wstest.client”,用来保存服务端和客户端程序。然后开始创建服务端程序,如下图

?

?

?
完成后,生成了一个Service的配置services.xml:
?
<? xml version ="1.0" encoding ="UTF-8" ?>
< beans xmlns ="http://xfire.codehaus.org/config/1.0" >

?? < service >
???? < name >MyService </ name >
???? < serviceClass >wstest.server.IMyService </ serviceClass >
???? < implementationClass >
??????wstest.server.MyServiceImpl
???? </ implementationClass >
???? < style >wrapped </ style >
???? < use >literal </ use >
???? < scope >application </ scope >
?? </ service >
</ beans >
?
也生成了接口和默认实现,改写后如下:
package wstest.server;
//Generated by MyEclipse

public interface IMyService {
????
?? public String sayHello(String user);
????
}
?
package wstest.server;
//Generated by MyEclipse

public class MyServiceImpl implements IMyService {
????
?? public String sayHello(String user) {
???? return "您好,"+user;
??}
????
}
?
至此,服务端代码已经完成。
?
3、测试服务端代码
?
测试依赖与Servlet容器Tomcat,需要将做好的服务端打包部署到tomcat上,然后启动。才可以进行测试。假设你已经配置了Tomcat服务器,并完成了WebService服务端的部署。那么,现在就启动Tomcat,然后:
?

?

?
输入访问地址: [url]http://localhost:8080/xfire126Demo/services/MyService?wsdl[/url]? ,然后go一把!
?

?

?
这样,出现上上面的结果,表明测试成功了。
?
4、生成客户端代码
?

?

?

?

?
很郁闷,这个生成的客户端代码一部分跑到服务端的包里面了。真是垃圾,rubbish!!!
?
但是,这就是MyEclipse的功能,我改变不了。
?
5、客户端测试
?
下面就耐心看怎么用这个客户端代码。
打开生成的代码如下:

package wstest.client;

import java.net.MalformedURLException;
import java.util.Collection;
import java.util.HashMap;
import javax.xml.namespace.QName;
import org.codehaus.xfire.XFireRuntimeException;
import org.codehaus.xfire.aegis.AegisBindingProvider;
import org.codehaus.xfire.annotations.AnnotationServiceFactory;
import org.codehaus.xfire.annotations.jsr181.Jsr181WebAnnotations;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.jaxb2.JaxbTypeRegistry;
import org.codehaus.xfire.service.Endpoint;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.soap.AbstractSoapBinding;
import org.codehaus.xfire.transport.TransportManager;

public class MyServiceClient {

???????? private static XFireProxyFactory proxyFactory = new XFireProxyFactory();
???????? private HashMap endpoints = new HashMap();
???????? private Service service0;

???????? public MyServiceClient() {
????????????????create0();
????????????????Endpoint MyServicePortTypeLocalEndpointEP = service0 .addEndpoint( new QName( "http://server.wstest","MyServicePortTypeLocalEndpoint"),new QName("http://server.wstest","MyServicePortTypeLocalBinding"),"xfire.local://MyService");
????????????????endpoints.put(new QName("http://server.wstest",MyServicePortTypeLocalEndpointEP);
????????????????Endpoint MyServiceHttpPortEP = service0 .addEndpoint(new QName("http://server.wstest","MyServiceHttpPort"),"MyServiceHttpBinding"),"http://localhost:8080/xfire126Demo/services/MyService");
????????????????endpoints.put(new QName("http://server.wstest",MyServiceHttpPortEP);
????????}

????????public Object getEndpoint(Endpoint endpoint) {
????????????????try {
????????????????????????return proxyFactory.create((endpoint).getBinding(),(endpoint).getUrl());
????????????????} catch (MalformedURLException e) {
????????????????????????throw new XFireRuntimeException("Invalid URL",e);
????????????????}
????????}

????????public Object getEndpoint(QName name) {
????????????????Endpoint endpoint = ((Endpoint) endpoints.get((name)));
????????????????if ((endpoint) == null) {
????????????????????????throw new IllegalStateException("No such endpoint!");
????????????????}
????????????????return getEndpoint((endpoint));
????????}

????????public Collection getEndpoints() {
????????????????return endpoints.values();
????????}

????????private void create0() {
????????????????TransportManager tm = (org.codehaus.xfire.XFireFactory.newInstance().getXFire().getTransportManager());
????????????????HashMap props = new HashMap();
????????????????props.put("annotations.allow.interface",true);
????????????????AnnotationServiceFactory asf = new AnnotationServiceFactory(new Jsr181WebAnnotations(),tm,new AegisBindingProvider(new JaxbTypeRegistry()));
????????????????asf.setBindingCreationEnabled(false);
????????????????service0 = asf.create((wstest.client.MyServicePortType.class),props);
????????????????{
????????????????????????AbstractSoapBinding soapBinding = asf.createSoap11Binding(service0,new QName("http://server.wstest","http://schemas.xmlsoap.org/soap/http");
????????????????}
????????????????{
????????????????????????AbstractSoapBinding soapBinding = asf.createSoap11Binding(service0,"urn:xfire:transport:local");

????????????????}
????????}

????????public MyServicePortType getMyServicePortTypeLocalEndpoint() {
????????????????return ((MyServicePortType)(this).getEndpoint(new QName("http://server.wstest","MyServicePortTypeLocalEndpoint")));
????????}

????????public MyServicePortType getMyServicePortTypeLocalEndpoint(String url) {
????????????????MyServicePortType var = getMyServicePortTypeLocalEndpoint();
????????????????org.codehaus.xfire.client.Client.getInstance(var).setUrl(url);
????????????????return var;
????????}

????????public MyServicePortType getMyServiceHttpPort() {
????????????????return ((MyServicePortType)(this).getEndpoint(new QName("http://server.wstest","MyServiceHttpPort")));
????????}

????????public MyServicePortType getMyServiceHttpPort(String url) {
????????????????MyServicePortType var = getMyServiceHttpPort();
????????????????org.codehaus.xfire.client.Client.getInstance(var).setUrl(url);
????????????????return var;
????????}

????????public static void main(String[] args) {
????????????????

????????????????MyServiceClient client = new MyServiceClient();
????????????????
????//create a default service endpoint
????????????????MyServicePortType service = client.getMyServiceHttpPort();
????????????????
????//TODO: Add custom client code here
????????????????????//
????????????????????//service.yourServiceOperationHere();
????????????????
????System.out.println("test client completed");
????????????????????System.exit(0);
????????}

}
?
看得很晕,不知道啥意思,但是从“TODO”标记处,我知道了:
???? //TODO: Add custom client code here
???????????????????? //
???????????????????? //service.yourServiceOperationHere();
?
现在就在这里添加测试代码吧:
???? //TODO: Add custom client code here
???????????????????? //
???????????????????? //service.yourServiceOperationHere();
????????????????String helloString = service.sayHello( "熔岩");
????????????????System.out.println(helloString);
?
添加了很傻蛋的两行代码后,就可以运行起来看看测试代码了。
