1.HelloWorld做了些什么?
HelloWorld功能非常简单,在客户端输入你的姓名,本例中为ZJ。参数传递到服务器端后,经过处理将返回name+"HelloWorld!",本例中为ZJ HelloWorld!
2.服务器端文件HelloWorld.java
HelloWorld.java
- package sample;??
- ???
- import org.apache.axiom.om.OMAbstractFactory;??
- import org.apache.axiom.om.OMElement;??
- import org.apache.axiom.om.OMFactory;??
- import org.apache.axiom.om.OMNamespace;??
- ???
- public class HelloWorld {??
- ??????
- ???????public OMElement sayHello(OMElement in){??
- ??????????
- ?????????????? String name=in.getText();??
- ?????????????? String info=name+"HelloWorld!";??
- ??????????
- ?????????????? OMFactory fac=OMAbstractFactory.getOMFactory();??
- ??????????
- ?????????????? OMNamespace omNs=fac.createOMNamespace("http://helloworld.com/","hw");??
- ??????????
- ?????????????? OMElement resp=fac.createOMElement("sayHelloResponse",omNs);??
- ??????????
- ?????????????? resp.setText(info);??
- ??????????????return resp;??
- ??????? }??
- }???
3.services.xml部署文件
services.xml
- <?xml version="1.0" encoding="UTF-8"?>??
- ??
- <service name="HelloWorld">??
- <description>??
- ?? This is a sample Web Service.??
- </description>??
- ??
- <parameter name="ServiceClass" locked="false">sample.HelloWorld</parameter>??
- ??
- <operation name="sayHello">??
- ??
- ?? <messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>??
- </operation>??
- </service>???
注解:消息交换模式。
目前Axis2支持三种模式:In-Only、Robust-In和In-Out。In-Only消息交换模式只有SOAP请求,而不需要应答; Robust-In消息交换模式发送SOAP请求,只有在出错的情况下才返回应答;In-Out消息交换模式总是存在SOAP请求和应答。本例使用In- Out模式。
4.客户端文件TestClient.java
- TestClient.java??
- package example.client;??
- ???
- import org.apache.axiom.om.OMAbstractFactory;??
- import org.apache.axiom.om.OMElement;??
- import org.apache.axiom.om.OMFactory;??
- import org.apache.axiom.om.OMNamespace;??
- import org.apache.axis2.addressing.EndpointReference;??
- import org.apache.axis2.client.Options;??
- import org.apache.axis2.client.ServiceClient;??
- ???
- public class TestClient {??
- ??????
- ???????private static EndpointReference targetEPR=new EndpointReference??
- ????????? ("http://localhost:8080/axis2/services/HelloWorld");??
- ???????public static OMElement getSayHelloOMElement(){??
- ??????????
- ?????????????? OMFactory fac=OMAbstractFactory.getOMFactory();??
- ??????????
- ?????????????? OMNamespace omNs=fac.createOMNamespace("http://helloworld.com/","hw");??
- ??????????
- ?????????????? OMElement method=fac.createOMElement("sayHello",omNs);??
- ??????????
- ?????????????? method.setText("ZJ");??
- ??????????????return method;??
- ??????? }??
- ???????public static void main(String[] args){??
- ??????????????try{??
- ????????????????????? Options options=new Options();??
- ????????????????????? options.setTo(targetEPR);??
- ????????????????????? ServiceClient sender=new ServiceClient();??
- ????????????????????? sender.setOptions(options);??
- ????????????????????? OMElement sayHello=TestClient.getSayHelloOMElement();??
- ??????????????
- ??
- ??
- ????????????????????? OMElement result=sender.sendReceive(sayHello);??
- ?????????????? }??
- ??????????????catch(Exception axisFault){??
- ????????????????????? axisFault.printStackTrace();??
- ?????????????? }??
- ??????? }??
- }???
5.Axis2简介 Apache Axis2 是Axis的后续版本,是新一代的SOAP引擎。Axis2的主要特点有: 1)采用名为 AXIOM(AXIs Object Model)的新核心 XML 处理模型,利用新的XML解析器提供的灵活性按需构造对象模型。 2)支持不同的消息交换模式。目前Axis2支持三种模式:In-Only、Robust-In和In-Out。In-Only消息交换模式只有 SOAP请求,而不需要应答;Robust-In消息交换模式发送SOAP请求,只有在出错的情况下才返回应答;In-Out消息交换模式总是存在 SOAP请求和应答。 3)提供阻塞和非阻塞客户端 API。 4)支持内置的 Web服务寻址 (WS-Addressing) 。 5)灵活的数据绑定,可以选择直接使用 AXIOM,使用与原来的 Axis 相似的简单数据绑定方法,或使用 XMLBeans、JiBX 或 JAXB 2.0 等专用数据绑定框架。 6)新的部署模型,支持热部署。 7)支持HTTP,SMTP,JMS,TCP传输协议。 8)支持REST (Representational State Transfer)。 6.Axis2 支持的规范包括: -SOAP 1.1 and 1.2 -Message Transmission Optimization Mechanism (MTOM),XML Optimized Packaging (XOP) and SOAP with Attachments -WSDL 1.1,including both SOAP and HTTP bindings -WS-Addressing (submission and final) -WS-Policy -SAAJ 1.1 有关Axis2更加详细的介绍,可以访问Axis2网站http://ws.apache.org/axis2/。
