步履艰难的XFire配置过程

步履维艰的XFire配置过程
1、拷贝xfire相关的jar到classpath；
2、在web.xml配置xfire的servlet及其url映射
xml 代码?

1. <servlet>??
2. ????<servlet-name>xfire<!---->servlet-name>??
3. ????<servlet-class>org.springframework.web.servlet.DispatcherServlet<!---->servlet-class>??
4. ????<init-param>??
5. ????????<param-name>contextConfigLocation<!---->param-name>??
6. ????????<param-value>classpath:xfire-servelet.xml<!---->param-value>??
7. ????<!---->init-param>??
8. <!---->servlet>??

3、新建xfire-servelet.xml
xml 代码?

1. xml?version="1.0"?encoding="UTF-8"?>??
2. >??
3. <beans>??
4. ????<import?resource="classpath:org/codehaus/xfire/spring/xfire.xml"/>??
5. ????<bean?class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">??
6. ????????<property?name="urlMap">??
7. ????????????<map>??
8. ????????????????<entry?key="/SAService">??
9. ????????????????????<ref?bean="SAServiceWS"?/>??
10. ????????????????<!---->entry>??
11. ????????????????<entry?key="/BulletinService">??
12. ????????????????????<ref?bean="BulletinServiceWS"?/>??
13. ????????????????<!---->entry>??
14. ????????????<!---->map>??
15. ????????<!---->property>??
16. ????<!---->bean>??
17. ??
18. ????<bean?id="SAServiceWS"?class="org.codehaus.xfire.spring.remoting.XFireExporter">??
19. ????????<property?name="serviceFactory">??
20. ????????????<ref?bean="xfire.serviceFactory"?/>??
21. ????????<!---->property>??
22. ????????<property?name="xfire">??
23. ????????????<ref?bean="xfire"?/>??
24. ????????<!---->property>??
25. ????????<property?name="serviceBean">??
26. ????????????<ref?bean="SAService"?/>??
27. ????????<!---->property>??
28. ????????<property?name="serviceClass">??
29. ????????????<value>net.gbicc.sa.service.SAService<!---->value>??
30. ????????<!---->property>??
31. ????<!---->bean>??
32. ??????
33. ????<bean?id="BulletinServiceWS"?class="org.codehaus.xfire.spring.remoting.XFireExporter">??
34. ????????<property?name="serviceFactory">??
35. ????????????<ref?bean="xfire.serviceFactory"?/>??
36. ????????<!---->property>??
37. ????????<property?name="xfire">??
38. ????????????<ref?bean="xfire"?/>??
39. ????????<!---->property>??
40. ????????<property?name="serviceBean">??
41. ????????????<ref?bean="bulletinService"?/>??
42. ????????<!---->property>??
43. ????????<property?name="serviceClass">??
44. ????????????<value>net.gbicc.swm.service.BulletinService<!---->value>??
45. ????????<!---->property>??
46. ????<!---->bean>??
47. <!---->beans>??

4、至此，算是把spring组件发布成webservice了，运气好的话访问http://localhost:8880/swm/services/SAService?wsdl可以看到xfire为我们生成的漂亮而复杂的WSDL。
5、可是，一般情况下不会这么顺利的（参考http://wiki.springside.org.cn/display/springside/XFire的2.3），我们还需要为那些返回值为集合类型的方法以及包含集合属性的model做一些特殊配置：
在SAService.java同一目录新建SAService.aegis.xml
xml 代码?

1. xml?version="1.0"?encoding="utf-8"?>??
2. <mappings>??
3. ????<mapping>??
4. ????????<method?name="getPrivileges">??
5. ????????????<return-type?componentType="net.gbicc.sa.domain.Privilege"?/>??
6. ????????<!---->method>??
7. ??
8. ????????<method?name="getDepts">??
9. ????????????<return-type?componentType="net.gbicc.sa.domain.Department"?/>??
10. ????????<!---->method>??
11. ??
12. ????????<method?name="getRoles">??
13. ????????????<return-type?componentType="net.gbicc.sa.domain.Role"?/>??
14. ????????<!---->method>??
15. ??
16. ????????<method?name="getUsers">??
17. ????????????<return-type?componentType="net.gbicc.sa.domain.User"?/>??
18. ????????<!---->method>??
19. ??
20. ????????<method?name="getUsersByDept">??
21. ????????????<return-type?componentType="net.gbicc.sa.domain.User"?/>??
22. ????????<!---->method>??
23. ??
24. ????????<method?name="getUsersByRole">??
25. ????????????<return-type?componentType="net.gbicc.sa.domain.User"?/>??
26. ????????<!---->method>??
27. ????<!---->mapping>??
28. <!---->mappings>??

在User.java同一目录新建User.aegis.xml
xml 代码?

1. xml?version="1.0"?encoding="utf-8"?>??
2. <mappings>??
3. ????<mapping>??
4. ????????<property?name="roles"?ignore="true"?/>??
5. ????<!---->mapping>??
6. <!---->mappings>??

6、再次启动服务，如果运气不是特别差的话，访问http://localhost:8880/swm/services/SAService?wsdl可以看到xfire为我们生成的漂亮而复杂的WSDL了。
7、可是，能够生成WSDL并不意味着程序已经可以访问这个Webservice，还要用单元测试来验证一下：
java 代码?

1. public?class?WSTest?extends?AbstractXFireSpringTest?{??
2. ????private?Log?log?=?LogFactory.getLog(WSTest.class);??
3. ??
4. ????protected?ApplicationContext?createContext()?{??
5. ????????return?new?ClassPathXmlApplicationContext(new?String[]?{?"classpath*:applicationContext*.xml",?"classpath*:xfire-servelet.xml"?});??
6. ????}??
7. ??
8. ????public?void?testSAWS()?throws?Exception?{??
9. ????????Service?serviceModel?=?new?ObjectServiceFactory().create(SAService.class);??
10. ????????XFireProxyFactory?factory?=?new?XFireProxyFactory(getXFire());??
11. ????????SAService?service?=?(SAService)?factory.create(serviceModel,?"xfire.local://SAService");??
12. ????????List?list?=?service.getPrivileges();??
13. ????????assertNotNull(list);??
14. ????}??
15. }??

因为继承了xfire提供的测试基类AbstractXFireSpringTest，使得我们可以不起服务就能测这个webservice。
8、如果运气不太差，应该可以看见绿条庆祝胜利了，可是，我却遇到了一个奇怪错误：org.codehaus.xfire.fault.XFireFault: No write method for property {http://domain.swm.gbicc.net}especialPrompt in class net.gbicc.swm.domain.Bulletin
而事实上Bulletin里并没有especialPrompt属性。。。。这令我很困惑，一度怀疑是Model继承导致的
后来终于找到症结所在——Bulletin里面的一些boolean isxxx方法把xfire骗了，为他们新建一些对应的setxxx(boolean)就没问题了，绿条如约出现。

整个过程虽然有些艰难，但是其实配置量还是很少的，再看看xfire替我们生成的一大堆WSDL，也就释然了，谁教咱程序员以“懒惰”为美德呢？
