本文介绍如何使用XFIRE结合Spring发布WebService，并通过JavaScript进行调用。文章详细解释了发布过程所需的步骤及配置文件设置。

1. xfire + spring 发布webservice
2. 利用 javascript 调用发布的webservice

使用xfire +spring 发布webservice其实很简单,遵循一下几个步骤即可

1. 想要发布成文webservice的类,必须实现接口
2. 3个配置文件(后面详细说)

下面针对以上步骤详细说明
关于1中的要求,给个例子就明白了

Itest.java 代码

package test;
import org.json.JSONException;
public interface IHello
{
public String hello();
public String helloTo(String name);
public String getJsonData(String pageIndex,String pageSize);
}

HelloImpl.java 代码

package test;
import java.util.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.codehaus.xfire .transport.http.XFire ServletController;
import org.json.JSONException;
import org.json.JSONStringer;
public class HelloImpl implements IHello
{
public String hello()
{
return "hello" ;
}
public String helloTo(String name)
{
return " hello " + name + "!" ;
}
private void example()
{
//使用session
HttpServletRequest request = XFire ServletController.getRequest();
HttpSession session = request.getSession();
}
public String getJsonData(String pageIndex,String pageSize)
{
String rtnValue = "" ;
rtnValue = "" ;
for ( int i= 0 ;i<Integer.parseInt(pageSize);i++)
{
rtnValue = rtnValue + "{'lastname': 'last" + pageIndex + "-" + i + "', 'firstname': 'first" + pageIndex + "-" + i + "' }," ;
}
rtnValue = rtnValue + "{'lastname': 'last', 'firstname': 'last' }" ;
rtnValue = "{'context':[" + rtnValue + "],'pager':[{'totalRecord':'100','totalpage':'10','pageIndex':'" + pageIndex + "','pageSize':'10'}]}" ;
return rtnValue;
}
}

就这样写就可以了

关于三个配置文件

web.xml修改如下

xml 代码

<? xml version = "1.0" encoding = "UTF-8" ?>
< web-app xmlns = "http://java.sun.com/xml/ns/j2ee" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" version = "2.4" 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 > log4jConfigLocation </ param-name >
< param-value > /WEB-INF/classes/log4j.properties </ param-value >
</ context-param >
< context-param >
< param-name > contextConfigLocation </ param-name >
< param-value >
/WEB-INF/classes/applicationContext*.xml
classpath:org/codehaus/xfire /spring /xfire .xml
</ param-value >
</ context-param >
< listener >
< listener-class >
org.spring framework.web.context.ContextLoaderListener
</ listener-class >
</ listener >
< listener >
< listener-class > org.spring framework.web.util.Log4jConfigListener </ listener-class >
</ listener >
< listener >
< listener-class >
org.spring framework.web.util.IntrospectorCleanupListener
</ listener-class >
</ listener >
< servlet >
< servlet-name > xfire </ servlet-name >
< servlet-class > org.spring framework.web.servlet.DispatcherServlet </ servlet-class >
</ servlet >
< servlet-mapping >
< servlet-name > xfire </ servlet-name >
< url-pattern > *.ws </ url-pattern >
</ servlet-mapping >
< welcome-file-list >
< welcome-file > index.html </ welcome-file >
</ welcome-file-list >
</ web-app >

这里注意 classpath:org/codehaus/xfire /spring /xfire .xml 必须要写进去

xfire -servlet.xml 新建这个文件,并且和web.xml放在同一个文件夹
注意: 名称和位置都不能变(也许可以改,我不知道)

xml 代码

<? xml version = "1.0" encoding = "UTF-8" ?>
<!DOCTYPE beans PUBLIC "-//SPRING //DTD BEAN//EN" "http://www.spring framework.org/dtd/spring -beans.dtd">
< beans >
< bean class = "org.spring framework.web.servlet.handler.SimpleUrlHandlerMapping" >
< property name = "urlMap" >
< map >
< entry key = "/testService.ws" >
< ref bean = "test" />
</ entry >
</ map >
</ property >
</ bean >
< bean id = "test" parent = "webService" class = "org.codehaus.xfire .spring .remoting.XFire Exporter" >
< property name = "serviceBean" >
< ref bean = "testBean" />
</ property >
< property name = "serviceClass" >
< value > test.IHello </ value >
</ property >
</ bean >
< bean id = "webService" class = "org.codehaus.xfire .spring .remoting.XFire Exporter" abstract = "true" >
< property name = "serviceFactory" >
< ref bean = "xfire .serviceFactory" />
</ property >
< property name = "xfire " >
< ref bean = "xfire " />
</ property >
</ bean >
</ beans >

spring 的配置文件 applicationContext-webService.xml

xml 代码

<? xml version = "1.0" encoding = "UTF-8" ?>
<!DOCTYPE beans PUBLIC "-//SPRING //DTD BEAN//EN" "http://www.spring framework.org/dtd/spring -beans.dtd">
< beans >
< bean id = "testBean" class = "test.HelloImpl" > </ bean >
</ beans >
