xfire + struts + spring 开发webservices例子

1.新建web project  工程名：WSST  （附件可下载）
2.导入struts  、spring  （过程略……），导好后结构如下：
（下图中少了xfire 1.2 core libraries ，这个MyEclipse自带的有该包，用add libraries可导入进来。）


3.编写服务器端代码：
   服务接口类：

package com.wsst.service;

public interface HelloWorld {
	public String execute(String message);
}

   服务具体实现类：

package com.wsst.service;

public class HelloWorldImpl implements HelloWorld {

	public String execute(String message) {
		// TODO Auto-generated method stub
		 return "您输入的内容是：" + message;
	}
}

业务服务bean

package com.wsst.service;

public class ServiceBean {

}

4.修改配置文件
   Spring配置文件（2.0版本生成的application.xml直接添加有点问题 ，把声明文件改成同struts-config.xml一致即可）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" 
	"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
	<!-- 服务实现类 -->
	<bean id="HelloServiceBean" class="com.wsst.service.HelloWorldImpl"/>
</beans>

   在WebRoot/WEB_INF/下增加 xfire-servlet.xml（注意同web中配置的xfire有关联）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
    "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

	<!-- 引入XFire预配置信息 -->
	<import resource="classpath:org/codehaus/xfire/spring/xfire.xml" />
	
	<!-- 定义访问的url-->
	<bean
		class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
		<property name="urlMap">
			<map>
				<entry key="/HelloService.ws">
					<ref bean="HelloService" />
				</entry>
			</map>
		</property>
	</bean>

	<!-- 使用XFire导出器 -->
	<bean id="baseWebService"
		class="org.codehaus.xfire.spring.remoting.XFireExporter"
		lazy-init="false" abstract="true">
		<!-- 引用xfire.xml中定义的工厂 -->
		<property name="serviceFactory" ref="xfire.serviceFactory" />
		<!-- 引用xfire.xml中的xfire实例 -->
		<property name="xfire" ref="xfire" />
	</bean>

	<bean id="HelloService" parent="baseWebService">
		<!-- 业务服务bean -->
		<property name="serviceBean" ref="HelloServiceBean" />
		<!-- 业务服务bean的窄接口类 -->
		<property name="serviceClass" value="com.wsst.service.HelloWorld" />
	</bean>

</beans>

   在web.xml中增加如下内容：

<servlet>  
        <!-- 此servlet名称对应xfire的spring配置文件为(servlet名称-servlet.xml),既为xfire-servlet.xml--> 
        <servlet-name>xfire</servlet-name>  
        <servlet-class>  
            org.springframework.web.servlet.DispatcherServlet   
        </servlet-class>  
        <load-on-startup>0</load-on-startup>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>xfire</servlet-name>  
        <url-pattern>*.ws</url-pattern>  
    </servlet-mapping>  
    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>/WEB-INF/applicationContext.xml</param-value>  
    </context-param>  
    <listener>  
        <listener-class>  
            org.springframework.web.context.ContextLoaderListener   
        </listener-class>  
    </listener>  

到此都已经配好了，发布项目，打开IE输入
http://localhost:8080/WSST/HelloService.ws?wsdl 即可访问。
