Spring + axis2 开发 webservice

来源：互联网发布：mac系统word怎么求和编辑：程序博客网时间：2024/05/17 12:20

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>
<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;}

</head>
<body>

<%
    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>
<%@
page contentType="text/html;charset=UTF-8" language="java"
%><%@

            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>

</head>
<body>

<%
    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;
    }
}
//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();
}
//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;
    }
}
//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>
<?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>
<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>
<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());
        }
    }
}
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
