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
}
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
}
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
}
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
} 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
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
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
}
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>
<?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。
最近有些朋友因使用Spring2.0以上版本时,会发生如下异常:
ERROR - Error initializing XFireServlet.
org.springframework.beans.factory.BeanDefinitionStoreException: Unrecognized xbean element mapping: beans in namespace http://xfire.codehaus.org/config/1.0
当出现如下异常时,请将此文件用如下内容替换:
1
<?xml version="1.0" encoding="UTF-8"?>
2
<beans>
3
<service xmlns="http://xfire.codehaus.org/config/1.0"
4
xmlns:s="http://www.springframework.org/schema/beans"
5
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
6
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
7
<name>HelloService</name>
8
<namespace>http://test/HelloService</namespace>
9
<serviceClass>test.IHelloService</serviceClass>
10
<implementationClass>test.HelloServiceImpl</implementationClass>
11
</service>
12
</beans>
13
<?xml version="1.0" encoding="UTF-8"?>2
<beans>3
<service xmlns="http://xfire.codehaus.org/config/1.0"4
xmlns:s="http://www.springframework.org/schema/beans"5
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"6
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">7
<name>HelloService</name>8
<namespace>http://test/HelloService</namespace>9
<serviceClass>test.IHelloService</serviceClass>10
<implementationClass>test.HelloServiceImpl</implementationClass>11
</service>12
</beans>13
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>
<?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。
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:
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
}
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
}
