Axis2是Apache的一个开源组件,你可以从Apache Project的网站http://ws.apache.org/axis2/中下载它的zip包,解压后,你会见到一个lib文件夹,在下例中,你需要导入以下几个jar包
axiom-api.jar
axis2-kernel.jar
commons-logging.jar
axiom-impl.jar
wsdl4j.jar
XmlSchema.jar
backport-util-concurrent.jar
neethi.jar
commons-httpclient.jar
commons-codec.jar
下面这个是WebService的Impl文件,虽然写客户端不需要用到它,客户端只需知道WebService的地址,并且由此找到最终发布的wsdl文件,就可以调用这个WebService了。这个类采用了JSR-181(JAX-WS),只需在类中加入一些简单的anotation,最终的WSDL文件及其它相关XML文件由这个类自动生成
package com.mycompany;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
@WebService(name = "TestService", serviceName = "TestService", targetNamespace = "http://www.mycompany.com")
public class TestService
{
@WebMethod(action = "http://www.mycompany.com/test")
@WebResult(name = "greeting")
public String test(@WebParam(name = "name") String name)
{
return "hello " + name;
}
}
下面这个类,就是客户端调用WebService的代码
package javaapplication1;
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 TestClient
{
private static void invokeWebService()
{
try
{
String soapBindingAddress = "http://localhost:9080/WebService/TestService";
EndpointReference endpointReference = new EndpointReference(soapBindingAddress);
//创建一个OMFactory,下面的namespace、方法与参数均需由它创建
OMFactory factory = OMAbstractFactory.getOMFactory();
//下面创建命名空间,如果你的WebService指定了targetNamespace属性的话,就要用这个
//对应于@WebService(targetNamespace = "http://www.mycompany.com")
OMNamespace namespace = factory.createOMNamespace("http://www.mycompany.com", "xsd");
//下面创建的是参数对数,对应于@WebParam(name = "name")
//由于@WebParam没有指定targetNamespace,所以下面创建name参数时,用了null,否则你得赋一个namespace给它
OMElement nameElement = nameElement = factory.createOMElement("name", null);
nameElement.addChild(factory.createOMText(nameElement, "java"));
//下面创建一个method对象,"test"为方法名
OMElement method = factory.createOMElement("test", namespace);
method.addChild(nameElement);
Options options = new Options();
options.setAction("http://www.mycompany.com/test"); //此处对应于@WebMethod(action = "http://www.mycompany.com/test")
options.setTo(endpointReference);
ServiceClient sender = new ServiceClient();
sender.setOptions(options);
//下面的输出结果为<xsd:test xmlns:xsd="http://www.mycompany.com"><name>java</name></xsd:test>
System.out.println(method.toString());
//发送并得到结果,至此,调用成功,并得到了结果
OMElement result = sender.sendReceive(method);
//下面的输出结果为<ns2:testResponse xmlns:ns2="http://www.mycompany.com"><greeting>hello java</greeting></ns2:testResponse>
System.out.println(result.toString());
}
catch (AxisFault ex)
{
ex.printStackTrace();
}
}
public static void main(String[] args)
{
TestClient.invokeWebService();
}
}
