【IT168 技术文档】
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
3import java.util.List;
4
5public 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。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
}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：
1package test;
2
3import java.util.ArrayList;
4import java.util.List;
5
6public 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：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
} 1package test;
2
3public 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
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
1package test;
2
3public 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}
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
}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>
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。<?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>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>
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。<?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>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>
<?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.XFireConfigurableServlet11
</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：
1package test;
2
3import java.net.MalformedURLException;
4import java.util.ArrayList;
5import java.util.List;
6
7import org.codehaus.xfire.XFireFactory;
8import org.codehaus.xfire.client.XFireProxyFactory;
9import org.codehaus.xfire.service.Service;
10import org.codehaus.xfire.service.binding.ObjectServiceFactory;
11
12public 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
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(XFireFactory19
.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
