webservice-之使用axis+spring开发（转自勇哥的BLOG）

一、环境配置?：在?eclipse?中配置引入相应的?Spring?框架（?core/Remoting/Web?）、?axis?包。

?

二、代码开发

1、??在?MyEclipse?中建立一个新的?J2EE?的?Web Project,?新建?java?包?test?。

2、??接口文件?HelloWorldRemote.java

package test;

//Spring?工程中要使用的接口文件

public interface HelloWorldRemote

{

???????public String?getMessage(String name);

}

3、??接口实现文件?HelloWorldBean.java

package test;

//Spring?工程中要使用的接口实现文件

public class HelloWorldBean implements HelloWorldRemote

{????

???????private String helloStr; // Spring?中需要注入的字符串???????

???????public String getHelloStr()

???????{

??????????????return helloStr;

???????}

???????public void setHelloStr(String helloStr)

???????{

??????????????this.helloStr = helloStr;

???????}

???????//?实现接口中的方法

???????public String?getMessage(String name)

???????{

??????????????return helloStr + ":" + name;

???????}????

}

4、??在?Spring?中对?Web Service?进行封装很简单，仅仅需要继承

org.springframework.remoting.jaxrpc.ServletEndpointSupport?类，实现里面的一些方法，包装一次，将其发布出来就可以。?HelloWorldWebService.java

package test;

import javax.xml.rpc.ServiceException;

import org.springframework.remoting.jaxrpc.ServletEndpointSupport;

public class HelloWorldWebService

??????????????extends ServletEndpointSupport

??????????????implements HelloWorldRemote

{

???????private HelloWorldRemote helloWorld;

???????protected void?onInit() throws ServiceException

???????{

??????????????//?在?Spring?容器中获取?Bean?的实例

??????????????helloWorld = (HelloWorldRemote) getApplicationContext()

????????????????????????????.getBean("myHelloWorldBean");

???????}

???????public String getMessage(String name)?

???????{

??????????????//?执行?Bean?中的相同的方法

??????????????return helloWorld.getMessage(name);

???????}

}

?

三、配置文件?（全部放在?/WEB-INF/?目录下?）

1、??web.xml?为?web?加载?spring?和?axis?配置

<!--Spring?框架需要引入的配置文件及相关类?-->

???????<context-param>

??????????????<param-name>contextConfigLocation</param-name>

??????????????<param-value>/WEB-INF/applicationContext.xml</param-value>

???????</context-param>

???????<servlet>

??????????????<servlet-name>context</servlet-name>

??????????????<servlet-class>

?????????????????????org.springframework.web.context.ContextLoaderServlet

??????????????</servlet-class>

??????????????<load-on-startup>1</load-on-startup>

???????</servlet>

???????<!--axis?需要引入的?Servlet -->

???????<servlet>

??????????????<servlet-name>axis</servlet-name>

??????????????<servlet-class>

?????????????????????org.apache.axis.transport.http.AxisServlet

??????????????</servlet-class>

??????????????<load-on-startup>2</load-on-startup>

???????</servlet>

???????<servlet-mapping>

??????????????<servlet-name>axis</servlet-name>

??????????????<url-pattern>/services/*</url-pattern>

???????</servlet-mapping>

???????<!--axis?的?Web Service?的?Web?发布路径?-->

2、??applicationContext.xml?为?spring?的配置

<?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="myHelloWorldBean" class="test.HelloWorldBean">

??????????????<property name="helloStr">

?????????????????????<value>Say Hello to :</value>

??????????????</property>

???????</bean>

</beans>

3、??server-config.wsdd?为?axis?服务配置

<deployment xmlns="http://xml.apache.org/axis/wsdd/"

???????xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

???????<handler name="URLMapper"

??????????????type="java:org.apache.axis.handlers.http.URLMapper" />???

???????<!--?系统服务?-->

???????<service name="AdminService" provider="java:MSG">

??????????????<parameter name="allowedMethods" value="AdminService" />

??????????????<parameter name="enableRemoteAdmin" value="false" />

??????????????<parameter name="className" value="org.apache.axis.utils.Admin" />

??????????????<namespace>http://xml.apache.org/axis/wsdd/</namespace>

???????</service>

???????<service name="Version" provider="java:RPC">

??????????????<parameter name="allowedMethods" value="getVersion" />

??????????????<parameter name="className" value="org.apache.axis.Version" />

???????</service>?????

???????<!--?自定义服务?-->

???????<service name="myWebService" provider="java:RPC">

??????????????<parameter name="className"

?????????????????????value="test.HelloWorldWebService" />

??????????????<parameter name="allowedMethods" value="*" />

???????</service>

???????<transport name="http">

??????????????<requestFlow>

?????????????????????<handler type="URLMapper" />

??????????????</requestFlow>

???????</transport>

</deployment>

?

四、测试?客户端?TestWebServiceClient.java

package test;

import javax.xml.namespace.QName;

import org.apache.axis.client.Call;

import org.apache.axis.client.Service;

public class TestWebServiceClient

{????

???????public static void main(String[] args)

???????{????

??????????????try

??????????????{

?????????????????????String wsdlUrl

= "http://localhost:8080/spring-axis/services/myWebService?wsdl";

?????????????????????String nameSpaceUri

= "http://localhost:8080/spring-axis/services/myWebService";

?????????????????????//?创建调用对象

?????????????????????Service service = new Service();

?????????????????????Call call = null;

?????????????????????call = (Call) service.createCall();

?????????????????????//?调用?getMessage

?????????????????????System.out.println(">>>getMessage");

?????????????????????call.setOperationName(new QName(nameSpaceUri,"getMessage"));

?????????????????????call.setTargetEndpointAddress(new java.net.URL(wsdlUrl));

?????????????????????String ret = (String) call.invoke(new Object[] { "ABC" });

?????????????????????System.out.println("return value is " + ret);

??????????????}

??????????????catch (Exception e)

??????????????{

?????????????????????e.printStackTrace();

??????????????}

???????}

}
