网上关于XFire入门的教程不少，要么是讲得很简单，就像Hello World一样的程序，要么就是通过IDE集成的工具来开发的，这对于不同的人群有诸多不便，关于XFire的一些详细的信息就不再多讲，可以参考官方网站和相关的文档，这里讲一个完整的入门实例。
实例中包括三个情况，我想基本上可以概括所有的需求，或者自己稍加扩展即可。先来看看我们的Interface。
1
package
test;
2
3 import java.util.List;
4
5 public interface IHelloService {
6 public String sayHello(String ttt);
7
8 public Course choose(User u);
9
10 public List test(List t);
11 }
2
3 import java.util.List;
4
5 public interface IHelloService {
6 public String sayHello(String ttt);
7
8 public Course choose(User u);
9
10 public List test(List t);
11 }
这其中包含了简单对象的传递，对象的传递，List的传递。
具体的开发步骤如下：
1、定义Web Service的接口，代码见上面的接口定义。
2、实现接口和业务逻辑，代码如下：
1
package
test;
2
3 import java.util.ArrayList;
4 import java.util.List;
5
6 public class HelloServiceImpl implements IHelloService {
7
8 public String sayHello(String ttt) {
9 return " Hello, " + ttt;
10 }
11
12 public Course choose(User u) {
13 System.out.println(u.getName());
14 Course c = new Course();
15 c.setName( " Eee " );
16 return c;
17
18 }
19
20 public List test(List t) {
21 for ( int i = 0 ; i < t.size(); i ++ ) {
22 System.out.println((String) t.get(i));
23 }
24 List al = new ArrayList();
25 Course c = new Course();
26 c.setName( " EeeDDDDDD " );
27 al.add(c);
28 return al;
29
30 }
31 }
2
3 import java.util.ArrayList;
4 import java.util.List;
5
6 public class HelloServiceImpl implements IHelloService {
7
8 public String sayHello(String ttt) {
9 return " Hello, " + ttt;
10 }
11
12 public Course choose(User u) {
13 System.out.println(u.getName());
14 Course c = new Course();
15 c.setName( " Eee " );
16 return c;
17
18 }
19
20 public List test(List t) {
21 for ( int i = 0 ; i < t.size(); i ++ ) {
22 System.out.println((String) t.get(i));
23 }
24 List al = new ArrayList();
25 Course c = new Course();
26 c.setName( " EeeDDDDDD " );
27 al.add(c);
28 return al;
29
30 }
31 }
用到的User和Course两个类的代码如下：
1
package
test;
2
3 public class User {
4 private String name;
5
6 public String getName() {
7 return name;
8 }
9
10 public void setName(String name) {
11 this .name = name;
12 }
13 }
14
2
3 public class User {
4 private String name;
5
6 public String getName() {
7 return name;
8 }
9
10 public void setName(String name) {
11 this .name = name;
12 }
13 }
14
1
package
test;
2
3 public class Course {
4 private String name;
5
6 public String getName() {
7 return name;
8 }
9
10 public void setName(String name) {
11 this .name = name;
12 }
13
14 }
2
3 public class Course {
4 private String name;
5
6 public String getName() {
7 return name;
8 }
9
10 public void setName(String name) {
11 this .name = name;
12 }
13
14 }
3、编写XFire要求的WebSevice定义描述文件，如下：
1
<?
xml version="1.0" encoding="UTF-8"
?>
2 < beans xmlns ="http://xfire.codehaus.org/config/1.0" >
3
4 < service >
5 < name > HelloService </ name >
6 < namespace > http://test/ HelloService </ namespace >
7 < serviceClass > test.IHelloService </ serviceClass >
8 < implementationClass > test.HelloServiceImpl </ implementationClass >
9 </ service >
10
11 </ beans >
2 < beans xmlns ="http://xfire.codehaus.org/config/1.0" >
3
4 < service >
5 < name > HelloService </ name >
6 < namespace > http://test/ HelloService </ namespace >
7 < serviceClass > test.IHelloService </ serviceClass >
8 < implementationClass > test.HelloServiceImpl </ implementationClass >
9 </ service >
10
11 </ beans >
此文件放在src/META-INF/xfire/services.xml，编译时会自动编译到classes的相应目录下面。
4、因为我们用到了List等集合类型，所以需要定义Mapping关系，文件名为：src/test/IHelloService.aegis.xml，代码如下：
1
<?
xml version="1.0" encoding="UTF-8"
?>
2 < mappings >
3 < mapping >
4 < method name ="test" >
5 < parameter index ="0" componentType ="java.lang.String" />
6 < return-type componentType ="test.Course" />
7 </ method >
8 </ mapping >
9 </ mappings >
2 < mappings >
3 < mapping >
4 < method name ="test" >
5 < parameter index ="0" componentType ="java.lang.String" />
6 < return-type componentType ="test.Course" />
7 </ method >
8 </ mapping >
9 </ mappings >
请注意，此文件一定要放到与IHelloService.java相同的目录下面，否则会出错。
5、在Web.xml中配置XFire需要用到的Servlet，代码如下：
1
<?
xml version="1.0" encoding="UTF-8"
?>
2 < web-app version ="2.4" xmlns ="http://java.sun.com/xml/ns/j2ee"
3 xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"
4 xsi:schemaLocation ="http://java.sun.com/xml/ns/j2ee
5 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >
6
7 < servlet >
8 < servlet-name > XFireServlet </ servlet-name >
9 < servlet-class >
10 org.codehaus.xfire.transport.http.XFireConfigurableServlet
11 </ servlet-class >
12 </ servlet >
13
14 < servlet-mapping >
15 < servlet-name > XFireServlet </ servlet-name >
16 < url-pattern > /servlet/XFireServlet/* </ url-pattern >
17 </ servlet-mapping >
18
19 < servlet-mapping >
20 < servlet-name > XFireServlet </ servlet-name >
21 < url-pattern > /services/* </ url-pattern >
22 </ servlet-mapping >
23
24
25 < welcome-file-list >
26 < welcome-file > index.jsp </ welcome-file >
27 </ welcome-file-list >
28 </ web-app >
2 < web-app version ="2.4" xmlns ="http://java.sun.com/xml/ns/j2ee"
3 xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"
4 xsi:schemaLocation ="http://java.sun.com/xml/ns/j2ee
5 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >
6
7 < servlet >
8 < servlet-name > XFireServlet </ servlet-name >
9 < servlet-class >
10 org.codehaus.xfire.transport.http.XFireConfigurableServlet
11 </ servlet-class >
12 </ servlet >
13
14 < servlet-mapping >
15 < servlet-name > XFireServlet </ servlet-name >
16 < url-pattern > /servlet/XFireServlet/* </ url-pattern >
17 </ servlet-mapping >
18
19 < servlet-mapping >
20 < servlet-name > XFireServlet </ servlet-name >
21 < url-pattern > /services/* </ url-pattern >
22 </ servlet-mapping >
23
24
25 < welcome-file-list >
26 < welcome-file > index.jsp </ welcome-file >
27 </ welcome-file-list >
28 </ web-app >
此时Web Service的服务端就开发完成了。
我们来看看客户端的代码吧，也很简单，如下：
1
package
test;
2
3 import java.net.MalformedURLException;
4 import java.util.ArrayList;
5 import java.util.List;
6
7 import org.codehaus.xfire.XFireFactory;
8 import org.codehaus.xfire.client.XFireProxyFactory;
9 import org.codehaus.xfire.service.Service;
10 import org.codehaus.xfire.service.binding.ObjectServiceFactory;
11
12 public class Client {
13
14 public static void main(String[] args) {
15
16 Service srvcModel = new ObjectServiceFactory()
17 .create(IHelloService. class );
18 XFireProxyFactory factory = new XFireProxyFactory(XFireFactory
19 .newInstance().getXFire());
20
21 String helloWorldURL = " http://localhost:8080/xfiretest/services/ HelloService " ;
22 try {
23 IHelloService srvc = (IHelloService) factory.create(srvcModel,
24 helloWorldURL);
25 System.out.println(srvc.sayHello( " Robin " ));
26
27 User u = new User();
28 u.setName( " RRRRR " );
29 Course c = srvc.choose(u);
30 System.out.println(c.getName());
31
32 List al = new ArrayList();
33 al.add( " 1212 " );
34 al.add( " 2222 " );
35 List t = srvc.test(al);
36 for ( int i = 0 ; i < t.size(); i ++ ) {
37 Course co = (Course)t.get(i);
38 System.out.println(co.getName());
39 }
40
41
42 } catch (MalformedURLException e) {
43 e.printStackTrace();
44 }
45
46 }
47
48 }
49
2
3 import java.net.MalformedURLException;
4 import java.util.ArrayList;
5 import java.util.List;
6
7 import org.codehaus.xfire.XFireFactory;
8 import org.codehaus.xfire.client.XFireProxyFactory;
9 import org.codehaus.xfire.service.Service;
10 import org.codehaus.xfire.service.binding.ObjectServiceFactory;
11
12 public class Client {
13
14 public static void main(String[] args) {
15
16 Service srvcModel = new ObjectServiceFactory()
17 .create(IHelloService. class );
18 XFireProxyFactory factory = new XFireProxyFactory(XFireFactory
19 .newInstance().getXFire());
20
21 String helloWorldURL = " http://localhost:8080/xfiretest/services/ HelloService " ;
22 try {
23 IHelloService srvc = (IHelloService) factory.create(srvcModel,
24 helloWorldURL);
25 System.out.println(srvc.sayHello( " Robin " ));
26
27 User u = new User();
28 u.setName( " RRRRR " );
29 Course c = srvc.choose(u);
30 System.out.println(c.getName());
31
32 List al = new ArrayList();
33 al.add( " 1212 " );
34 al.add( " 2222 " );
35 List t = srvc.test(al);
36 for ( int i = 0 ; i < t.size(); i ++ ) {
37 Course co = (Course)t.get(i);
38 System.out.println(co.getName());
39 }
40
41
42 } catch (MalformedURLException e) {
43 e.printStackTrace();
44 }
45
46 }
47
48 }
49
以上代码均无注释，因为都非常简单，呵呵。如有不清楚的地方，请留言！
