Spring-+-axis2-开发-webserv

初次接触 axis2，发现用起来极端繁琐。网上搜了 N 多的资料，终于找到一种轻松实现的方法。

第一步：准备

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-fra

mework-2.0.8.zip

http://apache.etoak.com/ws/axis2/1_5/axis2-1.5-war.zip

第二步：新建 web service 项目：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：

<servlet> 
<servlet-name>AxisServlet</servlet-name> 
<servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-c
lass> 
<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

<%@
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

第三步：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

第四步：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：

package sample.weatherservice.service;
import sample.weatherservice.bean.Weather;
public interface IWeatherService {
void setWeather(Weather w);
Weather getWeather();
}
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;
} 
}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; 
} 
}
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 {
// 使用 RPC 方式调用 WebService
// 指定调用 WebService 的 URL
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());
} 
} 
}

新建 spring 配置文件：

ws-sample/WebRoot/WEB-INF/applicationContext.xml
<?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：
<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：weatherservice

在目录 weatherservice 下，新建文件夹：META-INF

在目录 META-INF 下新建文件 services.xml

services.xml 的内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<serviceGroup> 
<service name="WeatherService"> 
<description>WeatherService:Spring POJO Axis2 Service
Sample</description> 
<parameter
name="ServiceClass">sample.weatherservice.service.IWeatherService</pa
rameter>
<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>
