spring+xfire实现webservice简单例子

本文主要是介绍spring+xfire实现webservice简单例子，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

spring xfire是一种比较简单的webservcie方式，下面的步骤描述一个例子。
基本流程是：
1.加载spring，xfire jar文件
2.web.xml加载applicationContext.xml，xfire
3.创建java服务工程，创建远程对外服务接口，实现类，model对象
4.在applicationContext.xml中部署服务
5.测试webservice

1.创建一个web工程，加入Maven,pom.xml代码见：

<dependencies><dependency><groupId>org.codehaus.xfire</groupId><artifactId>xfire-aegis</artifactId><version>1.2.4</version></dependency><dependency><groupId>org.codehaus.xfire</groupId><artifactId>xfire-spring</artifactId><version>1.2.4</version></dependency><dependency><groupId>xalan</groupId><artifactId>xalan</artifactId><version>2.7.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>2.0</version></dependency></dependencies>

如果没有使用Maven，将如下jar文件加载到classpath下面：
activation-1.1.jar
aopalliance-1.0.jar
avalon-framework-4.1.3.jar
commons-attributes-api-2.1.jar
commons-beanutils-1.7.0.jar
commons-codec-1.3.jar
commons-httpclient-3.0.jar
commons-logging-1.1.jar
jaxen-1.1-beta-9.jar
jdom-1.0.jar
junit-3.8.1.jar
log4j-1.2.12.jar
logkit-1.0.1.jar
mail-1.4.jar
qdox-1.5.jar
servlet-api-2.3.jar
spring-1.2.6.jar
spring-aop-2.0.jar
spring-beans-2.0.jar
spring-context-2.0.jar
spring-core-2.0.jar
spring-web-2.0.jar
stax-api-1.0.1.jar
stax-utils-snapshot-20040917.jar
wsdl4j-1.6.1.jar
wstx-asl-3.2.0.jar
xalan-2.7.0.jar
xbean-2.2.0.jar
xbean-spring-2.7.jar
xercesImpl-2.6.2.jar
xfire-aegis-1.2.4.jar
xfire-annotations-1.2.4.jar
xfire-core-1.2.4.jar
xfire-spring-1.2.4.jar
xfire-xmlbeans-1.2.4.jar
xml-apis-1.0.b2.jar
xmlParserAPIs-2.6.2.jar
XmlSchema-1.1.jar

2.编辑web.xml

<context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet><servlet-name>xfire</servlet-name><servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class></servlet><servlet-mapping><servlet-name>xfire</servlet-name><url-pattern>/service/*</url-pattern></servlet-mapping>

3.创建java服务工程,在web工程中关联该java工程或将java服务工程打包jar放到web工程classpath下面。
服务对外接口:org.simpledev.spring.xfire.service

HelloServiceString sayHello(String username) throws RemoteException;User listUserById(int id) throws RemoteException;

接口实现类:org.simpledev.spring.xfire.service.impl

HelloServiceImpl implements HelloServicepublic User listUserById(int id) throws RemoteException {System.out.println("server listUserById invoke");User user = new User(id,"纪纱","女",12,"日本都立海原高校");return user;}public String sayHello(String username) throws RemoteException {System.out.println("server sayHello invoke");return "你好 " + username;}

model对象
  属性:id,username,sex,age,address
  提供构造函数
  每个属性提供getXXX(),setXXX()方法

4.编辑applicationContext.xml

<import resource="classpath:org/codehaus/xfire/spring/xfire.xml" /> <bean id="baseWebService" class="org.codehaus.xfire.spring.remoting.XFireExporter" lazy-init="false" abstract="true">  <property name="serviceFactory" ref="xfire.serviceFactory" />  <property name="xfire" ref="xfire" /> </bean> <bean id="userWS" class="org.simpledev.spring.xfire.service.impl.HelloServiceImpl"></bean> <bean id="userService" parent="baseWebService">  <property name="serviceBean" ref="userWS" />  <property name="serviceClass" value="org.simpledev.spring.xfire.service.HelloService" /> </bean>

测试部署是否成功,发布web工程,在IE地址栏中输入: http://127.0.0.1:8080/springxfire/service/,出现链接后: http://127.0.0.1:8080/springxfire/service/HelloService?wsdl
表示部署成功

5.测试工程

public static void main(String[] args) {try {Service serviceModel = new ObjectServiceFactory().create(HelloService.class);HelloService service = (HelloService) new XFireProxyFactory().create(serviceModel,"http://127.0.0.1:8080/springxfire/service/HelloService");//方法一 测试String str = service.sayHello("世界");System.out.println(str);//方法二 测试User user = service.listUserById(1);System.out.println("id:"+user.getId());System.out.println("username:"+user.getUsername());System.out.println("sex:"+user.getSex());System.out.println("age:"+user.getAge());System.out.println("address:"+user.getAddress());} catch (MalformedURLException e) {e.printStackTrace();} catch (RemoteException e) {e.printStackTrace();}}

发现的问题：在实际项目中，
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>2.0</version>
    </dependency>一些jar包与原来项目中的spring jar可能会产生冲突，可以将spring-web jar去掉或覆盖，如下：
(
aopalliance-1.0.jar
avalon-framework-4.1.3.jar
commons-logging-1.1.jar
log4j-1.2.12.jar
logkit-1.0.1.jar
servlet-api-2.3.jar
spring-aop-2.0.jar
spring-beans-2.0.jar
spring-context-2.0.jar
spring-core-2.0.jar
spring-web-2.0.jar
)
其次web.xml中注意加载：xfire，否则测试是否部署成功时，http://.../service/，其实请求的就是在web.xml中配置的servlet
