axis2操作webservice

最近要与别的公司做接口，用到了axis2，所以就在网上找些资料了解下，自己做了个小例子，发布与调用webservice

1.下载axis2
地址：http://axis.apache.org/axis2/java/core/download.cgi
下载Binary Distribution,axis2-1.6.2-bin.zip中包含了axis2所有jar，把jar包加入项目中

2.创建需要发布的服务

package com.dm.service;

public class HelloWorld {
	
	public String sayHello(String name) {
		return "Hello, " + name + ".";
	}

	public String saySorry(String name) {
		return "sorry, " + name + ".";
	}

	public String getWorld() {
		return "Hello, world!";
	}
}

3.编写web.xml及services.xml
将下载的axis2-1.6.2-bin.zip中webapp/web-inf/web.xml复制到项目中,去掉不需要的配置

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

      <welcome-file>/axis2-web/index.jsp</welcome-file>
    </welcome-file-list>

</web-app>

services.xml
如果只发布单个服务，则用<service></service>
如果发布多个服务，则用<serviceGroup><service></service></serviceGroup>

<serviceGroup>
	<service name="HelloWorld">
		<description>
			HelloWorld Service Example
		</description>
		<parameter name="ServiceClass">
			com.dm.service.HelloWorld
		</parameter>
		<!-- 当不指定operation时必须加上这个
		<messageReceivers>
			<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
			<messageReceiver  mep="http://www.w3.org/2004/08/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
		</messageReceivers> -->
		<operation name="sayHello">
			<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
		</operation>
		<operation name="saySorry">
			<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
			<!-- 有返回值 -->
		</operation>
		<operation name="getWorld">
			<messageReceiver
				class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
				<!-- 无返回值 -->
		</operation>
	</service>
	
	<!-- <service name="weather">
		<description>
			getWeather
		</description>
		<parameter name="ServiceClass">
			com.dm.service.impl.WeatherImpl
		</parameter>
		<messageReceivers>
			<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
			<messageReceiver  mep="http://www.w3.org/2004/08/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
		</messageReceivers>
		<operation name="getWeather">
			<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
		</operation>
	</service> -->
</serviceGroup>

这里要注意下services.xml的放置位置



4.运行发布服务
测试地址：http://127.0.0.1:8080/axisforWebService/services/HelloWorld?wsdl
打开如下图则说明发布成功了

好了，服务现在已经发布了，下面我们来调用这个服务

5.调用服务
方式一：

package common;

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.Constants;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;

public class TestWebservice {
	private static EndpointReference targetEPR = new EndpointReference(
			"http://localhost:8080/axisforWebService/services/HelloWorld");

	public static OMElement sayHello(String symbol) {
		OMFactory fac = OMAbstractFactory.getOMFactory();
		OMNamespace omNs = fac
				.createOMNamespace("http://service.dm.com", "tns");
		OMElement method = fac.createOMElement("saySorry", omNs);
		OMElement value = fac.createOMElement("name", omNs);
		value.addChild(fac.createOMText(value, symbol));
		method.addChild(value);
		return method;
	}

	public static void main(String[] args) {
		try {
			OMElement getPassenger = sayHello("heiwado");
			Options options = new Options();
			options.setTo(targetEPR);
			options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
			ServiceClient sender = new ServiceClient();
			sender.setOptions(options);
			OMElement result = sender.sendReceive(getPassenger);
			String response = result.getFirstElement().getText();
			System.err.println("Current passengers: " + result);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

运行结果：Current passengers: <ns:saySorryResponse xmlns:ns="http://service.dm.com"><ns:return>sorry, heiwado.</ns:return></ns:saySorryResponse>

方式二：

package common;

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.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;

public class WebserviceUtils {
	public static void main(String[] args) {
		try {
			ServiceClient sc = new ServiceClient();
			Options opts = new Options();
			opts.setTo(new EndpointReference(
					"http://localhost:8080/axisforWebService/services/HelloWorld"));
			opts.setAction("urn:echo");
			opts.setTimeOutInMilliSeconds(10000);
			sc.setOptions(opts);
			OMElement res = sc.sendReceive(createPayLoad());
			System.out.println(res);
		} catch (AxisFault e) {
			e.printStackTrace();
		}
	}

	public static OMElement createPayLoad() {
		OMFactory fac = OMAbstractFactory.getOMFactory();
		OMNamespace omNs = fac.createOMNamespace(
				"http://service.dm.com", "HelloWorld");
		OMElement method = fac.createOMElement("sayHello", omNs);
		OMElement value = fac.createOMElement("name", omNs);
		value.setText("hehaisu");
		method.addChild(value);
		return method;
	}
}

方式三:

package common;

import javax.xml.namespace.QName;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;

public class WebserviceUtils4 {
	public static void main(String[] args) {
		String url = "http://localhost:8080/axisforWebService/services/HelloWorld";
		String result = null;
		try {
			// 使用RPC方式调用WebService
			RPCServiceClient serviceClient = new RPCServiceClient();
			Options options = serviceClient.getOptions();
			// 指定调用WebService的URL
			EndpointReference targetEPR = new EndpointReference(url);
			options.setTo(targetEPR);
			// 在创建QName对象时，QName类的构造方法的第一个参数表示WSDL文件的命名空间名，也就是<wsdl:definitions>元素的targetNamespace属性值
			// // 指定要调用的getWorld方法及WSDL文件的命名空间.....
			QName opAddEntry = new QName("http://service.dm.com", "saySorry");
			//
			// 指定getGreeting方法的参数值，如果有多个，继续往后面增加即可，不用指定参数的名称
			Object[] opAddEntryArgs = new Object[] { "上海" };
			// 返回参数类型，这个和axis1有点区别
			// invokeBlocking方法有三个参数，其中第一个参数的类型是QName对象，表示要调用的方法名；
			// 第二个参数表示要调用的WebService方法的参数值，参数类型为Object[]；
			// 第三个参数表示WebService方法的返回值类型的Class对象，参数类型为Class[]。
			// 当方法没有参数时，invokeBlocking方法的第二个参数值不能是null，而要使用new Object[]{}
			// 如果被调用的WebService方法没有返回值，应使用RPCServiceClient类的invokeRobust方法，
			// 该方法只有两个参数，它们的含义与invokeBlocking方法的前两个参数的含义相同
			// 指定getGreeting方法返回值的数据类型的Class对象.....
			Class[] classes = new Class[] { String.class };
			// 调用getGreeting方法并输出该方法的返回值.......
			result = (String)serviceClient.invokeBlocking(opAddEntry,
					opAddEntryArgs, classes)[0];
			//调用无返回值的方法则用serviceClient.invokeRobust方法		
			//serviceClient.invokeRobust(opAddEntry, opAddEntryArgs);
			System.out.println(result);
			
			
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

好了，服务调用就先说到这了，下次再去弄下cxf
