使用XFire开发WebServices服务端
本文所用到的WebServices服务端,取自我的上一篇文章中的例子——使用XFire开发WebServices服务端
这里并未涉及到JSR 181 Annotations 的相关应用,具体的三种方式如下
① 通过WSDL地址来创建动态客户端
② 通过服务端提供的接口来创建客户端
③ 使用Ant通过WSDL文件来生成客户端
第一种方式:通过WSDL地址来创建动态客户端

package com.jadyer.client;
import java.net.MalformedURLException;
import java.net.URL;
import org.codehaus.xfire.client.Client;
/**
* 通过WSDL来创建动态客户端
* @see 此时需要在项目中引入XFire 1.2 Core Libraries和XFire 1.2 HTTP Client Libraries
*/
public class ClientFromWSDL {
public static void main(String[] args) throws MalformedURLException, Exception {
Client client = new Client(new URL("http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl"));
Object[] results11 = client.invoke("sayHello", new Object[]{"Jadyer22"});
System.out.println(results11[0]);
}
}
package com.jadyer.client;
import java.net.MalformedURLException;
import java.net.URL;
import org.codehaus.xfire.client.Client;
/**
* 通过WSDL来创建动态客户端
* @see 此时需要在项目中引入XFire 1.2 Core Libraries和XFire 1.2 HTTP Client Libraries
*/
public class ClientFromWSDL {
public static void main(String[] args) throws MalformedURLException, Exception {
Client client = new Client(new URL("http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl"));
Object[] results11 = client.invoke("sayHello", new Object[]{"Jadyer22"});
System.out.println(results11[0]);
}
}
第二种方式:通过服务端提供的端口来创建客户端
view plaincopy to clipboardprint?
package com.jadyer.client;
import java.net.MalformedURLException;
import java.util.List;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import com.jadyer.model.Person;
import com.jadyer.model.User;
import com.jadyer.server.HelloService;
/**
* 通过Web服务端提供的接口来创建客户端
* @see 客户端必须提供一个与服务端完全一致的接口,包名也要一致
* @see 在本例中,需要在客户端(即该项目)中提供HelloService.java接口,以及Person和User两个POJO类
* @see 并且此时需要在项目中引入XFire 1.2 Core Libraries和XFire 1.2 HTTP Client Libraries
*/
public class ClientFromInterface {
public static void main(String[] args)throws MalformedURLException{
//首先使用XFire的ObjectServiceFactory从HelloService接口创建一个服务模型serviceModel
//serviceModel包含服务的说明,换句话说,就是服务的元数据
//Create a metadata of the service
Service serviceModel = new ObjectServiceFactory().create(HelloService.class);
//访问的地址
String serviceURL = "http://127.0.0.1:8080/XFire_demo/services/XFireServer";
//通过查看org.codehaus.xfire.client.XFireProxyFactory源码发现
//下面两行代码与这里直接new XFireProxyFactory()的作用是等效的
//XFire xfire = XFireFactory.newInstance().getXFire();
//XFireProxyFactory factory = new XFireProxyFactory(xfire);
//为XFire获得一个代理工厂对象
//Create a proxy for the deployed service
XFireProxyFactory factory = new XFireProxyFactory();
//通过proxyFactory,使用服务模型serviceModel和服务端点URL(用来获得WSDL)
//得到一个服务的本地代理,这个代理就是实际的客户端
HelloService client = (HelloService)factory.create(serviceModel, serviceURL);
/**
* Invoke the service
* @see 调用服务的本地代理(即实际的客户端)中的方法,便得到我们需要的WebServcie
*/
/*--处理简单对象--*/
String serviceResponse = client.sayHello("Jadyer11");
System.out.println(serviceResponse);
/*--处理对象--*/
User u = new User();
u.setName("Jadyer99");
Person pp = client.getPerson(u);
System.out.println(pp.getName());
/*--处理List--*/
List<Person> personList = client.getPersonList(24, "Jadyer88");
for(Person p : personList){
System.out.println(p.getName());
}
}
}
package com.jadyer.client;
import java.net.MalformedURLException;
import java.util.List;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import com.jadyer.model.Person;
import com.jadyer.model.User;
import com.jadyer.server.HelloService;
/**

* @see 并且此时需要在项目中引入XFire 1.2 Core Libraries和XFire 1.2 HTTP Client Libraries
*/
public class ClientFromInterface {
public static void main(String[] args)throws MalformedURLException{
//首先使用XFire的ObjectServiceFactory从HelloService接口创建一个服务模型serviceModel
//serviceModel包含服务的说明,换句话说,就是服务的元数据
//Create a metadata of the service

HelloService client = (HelloService)factory.create(serviceModel, serviceURL);
/**

* @see 调用服务的本地代理(即实际的客户端)中的方法,便得到我们需要的WebServcie
*/
/*--处理简单对象--*/
String serviceResponse = client.sayHello("Jadyer11");
System.out.println(serviceResponse);
/*--处理对象--*/
User u = new User();
u.setName("Jadyer99");
Person pp = client.getPerson(u);
System.out.println(pp.getName());
/*--处理List--*/
List<Person> personList = client.getPersonList(24, "Jadyer88");
for(Person p : personList){
System.out.println(p.getName());
}
}
}
这是它要用到的接口和两个POJO类
view plaincopy to clipboardprint?
/**
* Web服务提供给客户端的接口
* @see 这是第二种方式创建的客户端,要用到的接口
*/
package com.jadyer.server;
import java.util.List;
import com.jadyer.model.Person;
import com.jadyer.model.User;
public interface HelloService {
public String sayHello(String name);
public Person getPerson(User u);
public List<Person> getPersonList(Integer age, String name);
}
/**
* 第二种方式创建的客户端,要用到的两个POJO类
*/
package com.jadyer.model;
public class User {
private String name;
/*--getter和setter略--*/
}
package com.jadyer.model;
public class Person {
private Integer age;
private String name;
/*--getter和setter略--*/
}
/**
* Web服务提供给客户端的接口
* @see 这是第二种方式创建的客户端,要用到的接口
*/
package com.jadyer.server;
import java.util.List;
import com.jadyer.model.Person;
import com.jadyer.model.User;
public interface HelloService {
public String sayHello(String name);
public Person getPerson(User u);
public List<Person> getPersonList(Integer age, String name);
}
/**
* 第二种方式创建的客户端,要用到的两个POJO类
*/
package com.jadyer.model;
public class User {
private String name;
/*--getter和setter略--*/
}
package com.jadyer.model;
public class Person {
private Integer age;
private String name;
/*--getter和setter略--*/
}
第三种方式:使用Ant通过WSDL文件来生成客户端
view plaincopy to clipboardprint?
package com.jadyer.client;
/**
* 使用Ant通过WSDL生成客户端
* @see 这里的ClientFromAnt.java是我自己创建的,并非Ant生成
* @see 这里要用到的JAR有:xfire-all-1.2.6.jar以及\\xfire-distribution-1.2.6\\lib\\目录中的所有JAR包
* @see 我们需要把这些JAR包都拷贝到Web Project\\WebRoot\\WEB-INF\\lib\\目录中
* @see 然后把build.xml和MyFirstXFireServer.wsdl都拷贝到下Web Project的根目录下即可
* @see 关于MyFirstXFireServer.wsdl文件,是我在WebServices服务启动后
* @see 访问http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl然后将其另存得到的
*/
public class ClientFromAnt {
public static void main(String[] args) {
XFireServerClient client = new XFireServerClient();
//String url = "http://127.0.0.1:8080/XFire_demo/services/XFireServer";
//String result = client.getXFireServerHttpPort(url).sayHello("Jadyer33");
//上面的两行代码,与下面的这一行代码,同效~~
String result = client.getXFireServerHttpPort().sayHello("Jadyer33");
System.out.println(result);
}
}
package com.jadyer.client;
/**
* 使用Ant通过WSDL生成客户端
* @see 这里的ClientFromAnt.java是我自己创建的,并非Ant生成
* @see 这里要用到的JAR有:xfire-all-1.2.6.jar以及\\xfire-distribution-1.2.6\\lib\\目录中的所有JAR包

*/
public class ClientFromAnt {
public static void main(String[] args) {
XFireServerClient client = new XFireServerClient();
//String url = "http://127.0.0.1:8080/XFire_demo/services/XFireServer";
//String result = client.getXFireServerHttpPort(url).sayHello("Jadyer33");
//上面的两行代码,与下面的这一行代码,同效~~
String result = client.getXFireServerHttpPort().sayHello("Jadyer33");
System.out.println(result);
}
}
用到的Ant文件,如下
view plaincopy to clipboardprint?
<?xml version="1.0" encoding="UTF-8"?>
<project name="wsgen" default="wsgen" basedir=".">
<path id="classpathId">
<fileset dir="./WebRoot/WEB-INF/lib">
<include name="*.jar" />
</fileset>
</path>
<taskdef classpathref="classpathId" name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask"/>
<target name="wsgen" description="generate client">
<wsgen outputDirectory="./src/" wsdl="MyFirstXFireServer.wsdl" binding="xmlbeans" package="com.jadyer.client" overwrite="true"/>
</target>
</project>
<?xml version="1.0" encoding="UTF-8"?>
<project name="wsgen" default="wsgen" basedir=".">
<path id="classpathId">
<fileset dir="./WebRoot/WEB-INF/lib">
<include name="*.jar" />
</fileset>
</path>
<taskdef classpathref="classpathId" name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask"/>
<target name="wsgen" description="generate client">
<wsgen outputDirectory="./src/" wsdl="MyFirstXFireServer.wsdl" binding="xmlbeans" package="com.jadyer.client" overwrite="true"/>
</target>
</project>
也可以使用下面的这个Ant文件
view plaincopy to clipboardprint?
<?xml version="1.0" encoding="UTF-8"?>
<project name="xfireAnt" basedir="." default="createClientCode">
<property name="xfirelib" value="${basedir}/WebRoot/WEB-INF/lib"/>
<property name="sources" value="${basedir}/src"/>
<path id="classpath">
<fileset dir="${xfirelib}">
<include name="*.jar"/>
</fileset>
</path>
<target name="createClientCode">
<taskdef name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask" classpathref="classpath"/>
<wsgen outputDirectory="${sources}" wsdl="http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl" package="com.jadyer.client" overwrite="true"/>
</target>
</project>
<?xml version="1.0" encoding="UTF-8"?>
<project name="xfireAnt" basedir="." default="createClientCode">
<property name="xfirelib" value="${basedir}/WebRoot/WEB-INF/lib"/>
<property name="sources" value="${basedir}/src"/>
<path id="classpath">
<fileset dir="${xfirelib}">
<include name="*.jar"/>
</fileset>
</path>
<target name="createClientCode">
<taskdef name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask" classpathref="classpath"/>
<wsgen outputDirectory="${sources}" wsdl="http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl" package="com.jadyer.client" overwrite="true"/>
</target>
</project>
最后我再把MyFirstXFireServer.wsdl的内容,附加上
