webservice-之使用axis+spring开发

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();

}

}

}
