XFire构建服务端Service的两种方式（转）

XFire构建服务端service的两种方式，一是用xfire构建，二是和spring集成构建。 

一，xifre构建，确保把xfire的jar包导入到工程中或classpath。 

1，service的接口类 

package cn.cjw.services.exchange;

public interface ExchangeService {
    public double RMB2Dollar(double RMB);
}

2，service的实现类 

package cn.cjw.services.exchange.impl;

import cn.cjw.services.exchange.ExchangeService;

public class ExchangeServiceImpl implements ExchangeService {

    private double EXCHANGERATE = 6.9;

    /**
     * @return the eXCHANGERATE
     */
    public double getEXCHANGERATE() {
        return EXCHANGERATE;
    }

    /**
     * @param exchangerate the eXCHANGERATE to set
     */
    public void setEXCHANGERATE(double exchangerate) {
        EXCHANGERATE = exchangerate;
    }

    public double RMB2Dollar(double RMB) {
        // TODO Auto-generated method stub
        return RMB*(1/EXCHANGERATE);
    }

}

3，在你的src文件夹下新建一个META-INF/xfire文件夹，同时新建一个services.xml文件。  services.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
    <service>
        <name>ExchangeService</name>
        <namespace>http://www.chinajavaworld.com/ExchangeService</namespace>
        <serviceClass>cn.cjw.services.exchange.ExchangeService</serviceClass>
        <implementationClass>cn.cjw.services.exchange.impl.ExchangeServiceImpl</implementationClass>
    </service>
</beans>

4,配置你的项目中的web.xml。

<?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">
  <servlet>
    <servlet-name>XFireServlet</servlet-name>
    <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</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>

到这里，把以上的工程导入到tomcat的webapps下就可以使用了。这和axis比起来，省略了打包的过程。部署到tomcat后启动，在浏览器输入http://localhost:port/[yourProjectName]/services/ExchangeService?wsdl，注意：这里的yourProjectName就是你建立的工程名字。如果ok，那么说明你的service已经可以部署ok了。 
二，集成spring的部署，spring和xfire的jar包需要导入到工程中。  1，建立service的接口类和实现类，代码和以上相同。  2，spring的applicationContext.xml文件 

<?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">

    <import resource="classpath:org/codehaus/xfire/spring/xfire.xml"/>

    <bean id="ExchangeService" class="org.codehaus.xfire.spring.remoting.XFireExporter">
        <property name="serviceFactory" ref="xfire.serviceFactory"></property>
        <property name="xfire" ref="xfire"></property>

        <property name="serviceBean" ref="ExchangeServiceImpl"></property>
        <property name="serviceClass" value="cn.cjw.services.exchange.ExchangeService"></property>
        <property name="name" value="ExchangeService"></property>
    </bean>

    <bean id="ExchangeServiceImpl" class="cn.cjw.services.exchange.impl.ExchangeServiceImpl"></bean>
</beans>

3，工程中的web.xml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>/WEB-INF/applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

    <servlet>
        <servlet-name>xfireSpringServlet</servlet-name>
        <servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>xfireSpringServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

</web-app>

把该工程部署到tomcat下，启动tomcat，在浏览器中输入：http://localhost:port/[yourProjectName]/services/ExchangeService?wsdl，如果ok，说明这个service已经部署ok了。相比前一个，这第二种方式可以说简便，而且能够使用spring的所有特性，如IOC和AOP。
