Spring+XFire开发[web service]
经过4天的努力,终于把XFire和Spring结合起来做了一个web service发布成功了!
首先建立一个工程,创建一个接口(XFiceFace):
package com.fire.face;
public interface XFireFace { public int doAdd(int i,int k);}
接着创建有一个实现类(XFireFace):
package com.fire.imservlet;
import com.fire.face.XFireFace;
public class XFireFaceIm implements XFireFace{ public int doAdd(int i,int k){ return i+k; }}
看过我前面文章的朋友很容易想到会去建立一个META-INF/xfire/service.xml文件.
因为集成了Spring,再次可以不必了.
因为web服务的定义在xfire-servlet.xml中可以找到。
接下来就该写配置文件了.
在WEB-INF文件夹下创建applicationContext.xml文件，这是Spring的配置文件.
需要说明的是,这个文件很重要.
里面的BEAN ,必须设置正确,然后在 XXX-SERVLET.XML 中把接口类和实现类都指定好才行.
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//Spring//DTD Bean//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><!-- Application Context --><beans>
<bean id="xfim" class="com.fire.imservlet.XFireFaceIm"/> <bean id="domInHandler" class="org.codehaus.xfire.util.dom.DOMInHandler" />
<bean id="wss4jTokenHandler" class="org.codehaus.xfire.security.wss4j.WSS4JInHandler" /></beans>
其中xfim这个bean,就是本工程发布的实现类
你可以只写一个...
当然你也可以在这个文件中定义其他的需要Spring管理的bean。
接下来配置xfire-servlet.xml
在WEB-INF文件夹下创建
根据Spring规范，我把这个文件名起做xfire-servlet.xml.
需要注意的是此处的xfire是在web.xml当中配置的DispatcherServlet的名称.
其中xfim是我在applicationContext.xml中配置的那个Bean.
map就是java.util.map
因为是个集合类.
此处实现了Spring的注入!
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//Spring//DTD Bean//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><!-- Application Context --><beans> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="urlMap"> <map> <entry key="/XFireFace"> <ref bean="XFireService"/> </entry> </map> </property> </bean> <bean id="XFireService" 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="xfim"/> </property> <property name="serviceClass"> <value>com.fire.face.XFireFace</value> </property> </bean></beans>
最后就是修改web.xml文件了
<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_ID" 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>/WEB-INF/applicationContext.xml 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>
</web-app>
OK此时启动服务器,我用的是tomcat5.0.28
控制台会输入如下信息，log4j有一个警告，不需管它!
log4j:WARN No appenders could be found for logger (org.apache.catalina.startup.Embedded).log4j:WARN Please initialize the log4j system properly.
log4j:WARN No appenders could be found for logger (org.apache.commons.beanutils.ConvertUtils).log4j:WARN Please initialize the log4j system properly.
然后可以在浏览器访问:http://localhost:8080/xfire/XFireFace?wsdl
浏览器输出以下服务信息，代表发布成功!
你将可以通过http://localhost:8080/xfire/XFireFace来调用此服务了!
