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:
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}
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:
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
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
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}
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}
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。
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
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
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>
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:
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}
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}
