WebService开发实例 (Xfire+Spring+Hibernate)

利用xfire编写webservice的例子,内容如下

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

packagetest;

importorg.json.JSONException;

publicinterfaceIHello
{
publicStringhello();
publicStringhelloTo(Stringname);
publicStringgetJsonData(StringpageIndex,StringpageSize);
}

HelloImpl.java 代码

packagetest;

importjava.util.*;

importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpSession;

importorg.codehaus.xfire.transport.http.XFireServletController;
importorg.json.JSONException;
importorg.json.JSONStringer;

publicclassHelloImplimplementsIHello
{

publicStringhello()
{
return"hello";
}

publicStringhelloTo(Stringname)
{
return"hello"+name+"!";
}

privatevoidexample()
{
//使用session
HttpServletRequestrequest=XFireServletController.getRequest();
HttpSessionsession=request.getSession();
}

publicStringgetJsonData(StringpageIndex,StringpageSize)
{
StringrtnValue="";

rtnValue="";
for(inti=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'}]}";

returnrtnValue;
}
}

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

<?xmlversion="1.0"encoding="UTF-8"?>
<web-appxmlns="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/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<!--配置文件路径开始-->
<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>

<!--启动时加载SpringContextServlet-->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

<listener>
<listener-class>
org.springframework.web.util.IntrospectorCleanupListener
</listener-class>
</listener>

<!--XFire配置-->
<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>*.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

<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEbeansPUBLIC"-//SPRING//DTDBEAN//EN""http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<beanclass="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<propertyname="urlMap">
<map>
<entrykey="/testService.ws">
<refbean="test"/>
</entry>
</map>
</property>
</bean>

<beanid="test"parent="webService"class="org.codehaus.xfire.spring.remoting.XFireExporter">
<propertyname="serviceBean">
<refbean="testBean"/>
</property>
<propertyname="serviceClass">
<value>test.IHello</value>
</property>
</bean>

<!--webServicebase-->
<beanid="webService"class="org.codehaus.xfire.spring.remoting.XFireExporter"abstract="true">
<propertyname="serviceFactory">
<refbean="xfire.serviceFactory"/>
</property>
<propertyname="xfire">
<refbean="xfire"/>
</property>
</bean>
</beans>

spring 的配置文件 applicationContext-webService.xml

xml 代码

<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEbeansPUBLIC"-//SPRING//DTDBEAN//EN""http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<beanid="testBean"class="test.HelloImpl"></bean>
</beans>

查看wsdl http://localhost:8080/mootools/testService.ws?wsdl

运行 进入 index.html 页面,点击 即可执行调用,正常显示表示发布成功,调用失败会返回error(运行前请修改index.html文件的源码,将url修改成真正的url)

例子很简单,不过多解释,源码查看附件
