這裡並未涉及JSR 181 Annotations 的相關應用，具體的三種方式如下
① 透過WSDL位址來建立動態客戶端
② 透過服務端提供的介面來建立客戶端
③ 使用Ant透過WSDL檔來產生客戶端
第一種方式：透過WSDL位址來建立動態客戶端
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]);
}
}
第二種方式：透過服務端提供的連接埠來用客戶端
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());
}
}
}/**
* 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--*/
}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);

下面的這個Ant檔案
<?xml version="1.0" encoding="UTF-8"?>

最後我再把MyFirstXFireServer.wsdl的內容，附加上

天在找XFire+Spring的資料的時候看到的，在這裡也是做個記錄。同樣的，這種方法和上面所提到的第二種方法在客戶端都需要與伺服器一樣的接口，包名也必須一樣。
（1）在src目錄下新建client.xml(名字並非特定)
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="baseService" class="org.codehaus.xfire.spring.remoting.XFireClientFactoryBean" lazy-init="false" abstract="true"/> <!-- id的名字作为标识，用于客户端程序中获取service，若有多个service咋在下面添加多个bean即可--> <bean id="MathService" parent="baseService"> <property name="serviceClass"> <value>service.MathService</value> </property> <property name="wsdlDocumentUrl"> <value>http://localhost:8080/myservice/mathWebService?wsdl</value> </property> </bean> </beans>
（2）在程式中呼叫服務程式碼非常簡單
ApplicationContext ctx = new ClassPathXmlApplicationContext("client.xml");
MathService mathService = (MathService)ctx.getBean("MathService");
int result = mathService.add(int one,int two);String wsdl = "mathWebService.wsdl " ; // 对应的WSDL文件 Resource resource = new ClassPathResource(wsdl); Client client = new Client(resource.getInputStream(), null ); // 根据WSDL创建客户实例 Object[] objArray = new Object[ 2 ]; objArray[ 0 ] = 2 ; obiArray[1] = 3; // 调用特定的Web Service方法 Object[] results = client.invoke( " add " , objArray); System.out.println( " result: " + results[ 0 ]);
