XFire与Spring结合的几种方式

1、使用org.codehaus.xfire.spring.XFireSpringServlet与ServiceBean
1.1 web.xml的配置

<web-app>
<display-name>Spring Image Database</display-name>
<description>Spring Image Database sample application</description>
<!--
  These values are used by ContextLoaderListener, defined immediately below.
        The files listed below are used to initialize the business logic portion of the application.
        Each dispatcher servlet (defined further down) has their own configuration file,
        which may or may not depend on items in these files.
    -->
    <context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>
     classpath:applicationContext-webservice.xml
    </param-value>
    </context-param>
<!-- Log4j configuration listener-->
<listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<!-- Spring framework -->
<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
        <servlet-name>XFireServlet</servlet-name>
        <display-name>XFire Servlet</display-name>
        <servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class>
    </servlet>
              
    <servlet-mapping>
        <servlet-name>XFireServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

<welcome-file-list>
  <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

</web-app>

1.2 applicationContext-webservice.xml的配置：

<beans>

    <import resource="classpath:org/codehaus/xfire/spring/xfire.xml"/>
   
    <bean name="echoService" class="org.codehaus.xfire.spring.ServiceBean">
        <property name="serviceBean" ref="echo"/>
        <property name="serviceClass" value="org.codehaus.xfire.test.Echo"/>
        <property name="inHandlers">
            <list>
                <ref bean="addressingHandler"/>
            </list>
        </property>
    </bean>

    <bean id="echo" class="org.codehaus.xfire.test.EchoImpl"/>

    <bean id="addressingHandler" class="org.codehaus.xfire.addressing.AddressingInHandler"/>

   <bean name="bookService" class="org.codehaus.xfire.spring.ServiceBean">
        <property name="serviceBean" ref="bookServiceBean"/>
        <property name="serviceClass" value="org.codehaus.xfire.demo.BookService"/>
    </bean>

    <bean id="bookServiceBean" class="org.codehaus.xfire.demo.BookServiceImpl"/>

</beans>

1.3 这样将会发布两个service，BookService和EchoService。随后就可以使用client端进行测试了。

     //测试BookService
    public static void main(String args[])
    {
        String serviceURL = "http://127.0.0.1:9001/xfire/services/BookService";
        Service serviceModel = new ObjectServiceFactory().create(BookService.class,null,"http://xfire.codehaus.org/BookService",null);
        XFireProxyFactory serviceFactory = new XFireProxyFactory();
        try
        {
            BookService service = (BookService) serviceFactory.create(serviceModel, serviceURL);
            Client client = Client.getInstance(service);
            client.addOutHandler(new OutHeaderHandler());
            Book[] books = service.getBooks();
            System.out.println("BOOKS:");
            for (int i = 0; i < books.length; i++)
            {
                System.out.println(books[i].getTitle());
            }
        }
        catch (MalformedURLException e)
        {
            e.printStackTrace();
        }
    }

1.4 忘了BookService及其实现了。

     public interface BookService
    {
              public Book[] getBooks();
   
              public Book findBook(String isbn);
   
             public Map getBooksMap();
   }



    public class BookServiceImpl implements BookService
    {
    private Book onlyBook;
   
    public BookServiceImpl()
    {
        onlyBook = new Book();
        onlyBook.setAuthor("Dan Diephouse");
        onlyBook.setTitle("Using XFire");
        onlyBook.setIsbn("0123456789");
     }

     public Book[] getBooks()
     {
        return new Book[] { onlyBook };
     }
   
     public Book findBook(String isbn)
     {
        if (isbn.equals(onlyBook.getIsbn()))
            return onlyBook;
       
        return null;
     }

     public Map getBooksMap() {
  Map result = new HashMap();
  result.put(onlyBook.getIsbn(), onlyBook);
  return result;
     }
    }

1.5 简单的测试就是通过IE，输入http://ip:port/context/services/BookService?wsdl或者http://ip:port/context/services/EchoService?wsdl，将会出现相应的wsdl文档。

     如果只是输入http://ip:port/context/services/BookService，会出现Invalid SOAP request.这也说明配置正确。

2、直接集成Spring（通过Spring的org.springframework.web.servlet.DispatcherServlet）

2.1 web.xml配置
<web-app>
<!-- START SNIPPET: xfire -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
        classpath:org/codehaus/xfire/spring/xfire.xml</param-value>
    </context-param>

    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>/WEB-INF/log4j.properties</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>xfire</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>xfire</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
<!-- END SNIPPET: xfire -->
</web-app>
2.2 xfire-servlet.xml配置
<beans>
    <!-- START SNIPPET: xfire -->
    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/EchoService">
                    <ref bean="echo"/>
                </entry>
            </map>
        </property>
    </bean>

    <bean id="echoBean" class="org.codehaus.xfire.spring.example.EchoImpl"/>

    <!-- Declare a parent bean with all properties common to both services -->
    <bean id="echo" class="org.codehaus.xfire.spring.remoting.XFireExporter">
        <property name="serviceFactory">
            <ref bean="xfire.serviceFactory"/>
        </property>
        <property name="xfire">
            <ref bean="xfire"/>
        </property>
        <property name="serviceBean">
            <ref bean="echoBean"/>
        </property>
        <property name="serviceClass">
            <value>org.codehaus.xfire.spring.example.Echo</value>
        </property>
    </bean>
    <!-- END SNIPPET: xfire -->
</beans>
2.3 余下的配置跟第一种方法一样。

3、另外xfire的官方文档上还有一种方法，是通过XBean与Spring结合来实现webservice的expose。还是觉得上面的两种方法比较好。既然已经与spring集成在一起了，何必再引入其他的呢？以后的维护是不是也要有问题呢？

在随后的文章里将会介绍xfire与Jibx结合的例子。
