Spring是目前最流行的JavaEE Framework,但是使用Spring的Spring-WS开发WebService却十分繁琐。XFire是一个简化WebService开发的开源项目,通过Spring和XFire的结合可以大大简化基于Spring Framework的应用中的WebService开发。
Spring和XFire可以通过多种方式结合,下文介绍的是笔者常用的一种简单而实用的方法。所用的Spring版本为2.0,XFire版本为1.2.6.
1、配置XFire Servlet
在web.xml中加入如下配置:
<servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class> org.codehaus.xfire.spring.XFireSpringServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/servlet/XFireServlet/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> |
2 配置Spring的监听器,同基于spring的Web项目一样Spring的监听器是必不可少的。
<context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:org/codehaus/xfire/spring/xfire.xml, /WEB-INF/applicationContext.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> |
以下是完整的web.xml配置文件
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:org/codehaus/xfire/spring/xfire.xml, /WEB-INF/applicationContext.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class> org.codehaus.xfire.spring.XFireSpringServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/servlet/XFireServlet/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> </web-app> |
3 定义接口及实现服务
定义接口,这个接口中定义要通过WebService暴露的方法
package org.ccsoft;
publicinterface HelloWS { public String sayHello(String sb); } |
实现服务
package org.ccsoft;
publicclass HelloWSImp implements HelloWS { public String sayHello(String sb) { // TODO Auto-generated method stub return"Hello "+sb; } } |
4 配置服务
将上文中实现的服务,加入到spring的配置文件中。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="helloWS" class="org.ccsoft.HelloWSImp"/> <bean name="helloService" class="org.codehaus.xfire.spring.ServiceBean"> <property name="serviceBean" ref="helloWS"/> <property name="serviceClass" value="org.ccsoft.HelloWS"/> <property name="inHandlers"> <list> <ref bean="addressingHandler"/> </list> </property> </bean>
<bean id="addressingHandler" class="org.codehaus.xfire.addressing. AddressingInHandler"/> </beans> |
