Axis2发布及调用WebService简单案例

布满荆棘的人生 2022-03-29 16:44 693阅读 0赞

### 1.下载axis2所需的jar包[http://mirrors.shu.edu.cn/apache/axis/axis2/java/core/1.7.9/axis2-1.7.9-bin.zip][http_mirrors.shu.edu.cn_apache_axis_axis2_java_core_1.7.9_axis2-1.7.9-bin.zip] ###

### 2.创建maven项目axis2-service，解压axis2-1.7.9-bin.zip文件，打开解压后的文件axis2-1.7.9，复制lib文件夹及其目录下的所有jar包到项目/axis2-service/src/main/webapp/WEB-INF目录下 ###

### 3.将lib下的jar包引入到项目中 ###

###  4.编写服务类SampleService.java ###

package com.szcatic.service;
    
    import javax.xml.stream.XMLStreamException;
    import org.apache.axiom.om.OMAbstractFactory;
    import org.apache.axiom.om.OMElement;
    import org.apache.axiom.om.OMFactory;
    import org.apache.axiom.om.OMNamespace;
    
    /**
     * http://localhost:8088/axis2-service/services/UserGuideSampleService?wsdl
     * @author zsx
     *
     */
    public class SampleService {
    
    	public OMElement sayHello(OMElement element) throws XMLStreamException {
    		element.build();
    		element.detach();
    
    		String rootName = element.getLocalName();
    		System.out.println("Reading " + rootName + " element");
    
    		OMElement childElement = element.getFirstElement();
    		String personToGreet = childElement.getText();
    
    		OMFactory fac = OMAbstractFactory.getOMFactory();
    		OMNamespace omNs = fac.createOMNamespace("http://example1.org/example1", "example1");
    		OMElement method = fac.createOMElement("sayHelloResponse", omNs);
    		OMElement value = fac.createOMElement("greeting", omNs);
    		value.addChild(fac.createOMText(value, "Hello, " + personToGreet));
    		method.addChild(value);
    
    		return method;
    	}
    
    	public void ping() {
    		System.out.println("ping");
    	}
    
    }

### 5.在/axis2-service/src/main/webapp/WEB-INF/services/hellworld/META-INF目录下创建services.xml文件 ###

<?xml version="1.0" encoding="UTF-8"?>
    
    <service name="UserGuideSampleService">
    	<description>
    		This is a sample service created in the Axis2 User's Guide
    	</description>
    
    	<parameter name="ServiceClass">com.szcatic.service.SampleService</parameter>
    
    	<operation name="sayHello">
    		<messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver" />
    	</operation>
    	<operation name="ping">
    		<messageReceiver class="org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver" />
    	</operation>
    </service>

### 6.在web.xml中配置servlet ###

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://java.sun.com/xml/ns/javaee"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    	version="2.5">
    	<display-name>axis2-service</display-name>
    	<servlet>
    		<display-name>Apache-Axis Servlet</display-name>
    		<servlet-name>AxisServlet</servlet-name>
    		<servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>AxisServlet</servlet-name>
    		<url-pattern>/services/*</url-pattern>
    	</servlet-mapping>
    </web-app>

### 7.将项目部署到tomcat，并启动tomcat服务 ###

8.打开浏览器，输入链接[http://localhost:8088/axis2-service/services/UserGuideSampleService?wsdl][http_localhost_8088_axis2-service_services_UserGuideSampleService_wsdl]

**从上面结果可以看出，服务发布成功**

### 9.编写客户端SampleClient.java ###

package com.szcatic.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.Constants;
    import org.apache.axis2.client.ServiceClient;
    
    public class SampleClient {
    
    	private static EndpointReference targetEPR = new EndpointReference(
    			"http://localhost:8088/axis2-service/services/UserGuideSampleService");
    
    	public static OMElement greetUserPayload(String personToGreet) {
    		OMFactory fac = OMAbstractFactory.getOMFactory();
    		OMNamespace omNs = fac.createOMNamespace("http://example1.org/example1", "example1");
    		OMElement method = fac.createOMElement("sayHello", omNs);
    		OMElement value = fac.createOMElement("personToGreet", omNs);
    		value.addChild(fac.createOMText(value, personToGreet));
    		method.addChild(value);
    		return method;
    	}
    
    	public static void main(String[] args) {
    		try {
    			OMElement payload = SampleClient.greetUserPayload("John");
    			Options options = new Options();
    			options.setTo(targetEPR);
    
    			options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
    
    			ServiceClient sender = new ServiceClient();
    			sender.setOptions(options);
    			OMElement result = sender.sendReceive(payload);
    
    			String response = result.getFirstElement().getText();
    			System.out.println(response);
    
    		} catch (Exception e) { 
    			System.out.println(e.toString());
    		}
    	}
    
    }

### 10.运行客户端代码 ###

log4j:WARN No appenders could be found for logger (org.apache.axiom.locator.DefaultOMMetaFactoryLocator).
    log4j:WARN Please initialize the log4j system properly.
    Hello, John

**从输出结果看出客户端调用服务端成功**

### 11.目录整体结构 ###
