Java编程>Webservice

Spring WebService Bean Web Apache

1.下载 spring-framework-2.0.8.zip 和 axis2-1.5-war.zip 备用：
http://nchc.dl.sourceforge.net/project/springframework/springframework-2/2.0.8/spring-framework-2.0.8.zip
http://apache.etoak.com/ws/axis2/1_5/axis2-1.5-war.zip

2.新建一个web工程：ws-sample

解压pring-framework-2.0.8.zip 和 axis2-1.5-war.zip
将 spring.jar 和 axis2/WEB-INF/lib 里的jar包拷贝到 ws-sample/WebRoot/WEB-INF/lib/

打开ws-sample/WebRoot/WEB-INF/web.xml，增加配置：

Xml代码

< servlet >
< servlet-name > AxisServlet </ servlet-name >
< servlet-class > org.apache.axis2.transport.http.AxisServlet </ servlet-class >
< load-on-startup > 1 </ load-on-startup >
</ servlet >
< servlet-mapping >
< servlet-name > AxisServlet </ servlet-name >
< url-pattern > /services/* </ url-pattern >
</ servlet-mapping >

新建一个JSP：/ws-sample/WebRoot/axis2-web/listServices.jsp

Jsp代码

<%@
page contentType="text/html;charset=UTF-8" language= "java"
%><%@
page import="org.apache.axis2.Constants,
org.apache.axis2.description.AxisOperation,
org.apache.axis2.description.AxisService,
java.util.Collection,
java.util.HashMap,
java.util.Iterator"
%><html>
<head><title>List Services</title>
<style>
h2{margin:20 0 5 0 ;}
ul{margin-top:5 ;}
</style>
</head>
<body>
<h1>Available services</h1>
<%
HashMap serviceMap = (HashMap) request.getSession().getAttribute(Constants.SERVICE_MAP);
Collection servicecol = serviceMap.values();
if(servicecol.size()==0 ){%>Available services is Empty.<%}
for (Iterator iterator = servicecol.iterator(); iterator.hasNext();) {
AxisService axisService = (AxisService) iterator.next();
Iterator opItr = axisService.getOperations();
String serviceName = axisService.getName();
%>
<h2><font color="blue" ><a href= "<%=serviceName %>?wsdl" target= "_blank" ><%=serviceName%></a></font></h2>
<i>Available Operations</i>
<ul>
<%
while (opItr.hasNext()) {
AxisOperation axisOperation = (AxisOperation) opItr.next();
%><li><%=axisOperation.getName().getLocalPart()%></li><%
}
%>
</ul>
<%
}
%>
</body>
</html>

部署至tomcat，然后访问：
http://localhost:8080/ws-sample/services/listServices
如果不出差错的话，可以看到 Available services is Empty

3.部署pojo服务
新建目录：ws-sample/WebRoot/WEB-INF/services/

将 axis2/WEB-INF/services/version.aar 拷贝至 ws-sample/WebRoot/WEB-INF/services/

刷新 http://localhost:8080/ws-sample/services/listServices
见到一个叫Version的服务，说明 version.aar 已成功部署

4.开发并部署基于 Spring ApplicationContex 的服务
创建接口：sample.weatherservice.service.IWeatherService
和类：
sample.weatherservice.bean.Weather
sample.weatherservice.service.impl.WeatherService
代码如下：

Java代码

//Weather.java
package sample.weatherservice.bean;
public class Weather {
float temperature;
String forecast;
boolean rain;
float howMuchRain;
public void setTemperature( float temp) {
temperature = temp;
}
public float getTemperature() {
return temperature;
}
public void setForecast(String fore) {
forecast = fore;
}
public String getForecast() {
return forecast;
}
public void setRain( boolean r) {
rain = r;
}
public boolean getRain() {
return rain;
}
public void setHowMuchRain( float howMuch) {
howMuchRain = howMuch;
}
public float getHowMuchRain() {
return howMuchRain;
}
}

Java代码

//IWeatherService.java
package sample.weatherservice.service;
import sample.weatherservice.bean.Weather;
public interface IWeatherService {
void setWeather(Weather w);
Weather getWeather();
}

Java代码

//WeatherService.java
package sample.weatherservice.service.impl;
import sample.weatherservice.bean.Weather;
import sample.weatherservice.service.IWeatherService;
public class WeatherService implements IWeatherService {
Weather weather;
public void setWeather(Weather w) {
weather = w;
}
public Weather getWeather() {
return weather;
}
}

新建spring配置文件：
ws-sample/WebRoot/WEB-INF/applicationContext.xml

Xml代码

<? xml version = "1.0" encoding = "UTF-8" ?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
< beans >
< bean id = "weatherService" class = "sample.weatherservice.service.impl.WeatherService" >
< property name = "weather" >
< bean class = "sample.weatherservice.bean.Weather" >
< property name = "temperature" value = "89.9" />
< property name = "forecast" value = "Sunny" />
< property name = "rain" value = "false" />
< property name = "howMuchRain" value = "0.2" />
</ bean >
</ property >
</ bean >
</ beans >

修改 ws-sample/WebRoot/WEB-INF/web.xml 增加：

Xml代码

< 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 >

在 ws-sample/WebRoot/WEB-INF/services/ 目录下，新建文件夹和文件 weatherservice/META-INF/services.xml
services.xml的内容如下：

Xml代码

< serviceGroup >
< service name = "WeatherService" >
< description > WeatherService:Spring POJO Axis2 Service Sample </ description >
< parameter name = "ServiceClass" > sample.weatherservice.service.IWeatherService </ parameter >
< parameter name = "ServiceObjectSupplier" >
org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier
</ parameter >
< parameter name = "SpringBeanName" > weatherService </ parameter >
< messageReceivers >
< messageReceiver mep = "http://www.w3.org/2004/08/wsdl/in-out"
class = "org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</ messageReceivers >
</ service >
</ serviceGroup >

刷新 http://localhost:8080/ws-sample/services/listServices
见到新增了一个叫WeatherService的服务，说明 WeatherService 已成功部署

5.开发客户端调用

创建类：client.WeatherRPCClient

Java代码

package client;
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
import sample.weatherservice.bean.Weather;
public class WeatherRPCClient {
public static void main(String[] args1) throws AxisFault {
EndpointReference targetEPR = new EndpointReference( "http://localhost:8080/ws-sample/services/WeatherService" );
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
options.setTo(targetEPR);
QName opGetWeather = new QName( "http://service.weatherservice.sample" , "getWeather" );
Object[] opGetWeatherArgs = new Object[] { };
Class[] returnTypes = new Class[] { Weather. class };
Object[] response = serviceClient.invokeBlocking(opGetWeather,opGetWeatherArgs, returnTypes);
Weather result = (Weather) response[0 ];
if (result == null ) {
System.out.println("Weather didn't initialize!" );
}else {
System.out.println();
System.out.println("Temperature : " + result.getTemperature());
System.out.println("Forecast : " + result.getForecast());
System.out.println("Rain : " + result.getRain());
System.out.println("How much rain (in inches) : " + result.getHowMuchRain());
}
}
}

运行 WeatherRPCClient，输出如下，说明调用成功：
Temperature               : 89.9
Forecast                  : Sunny
Rain                      : false
How much rain (in inches) : 0.2
