如何在Axis2中添加SOAP头

还是使用之前的工程

WSDL文件生成方式参照：

http://www.voidcn.com/article/p-tgvubtje-tu.html

客户端代码生成方式参照：

http://www.voidcn.com/article/p-qwqfppbn-tu.html

最后生成的客户端代码格式如下：

MathStub.java类中的add方法有下面这一段代码：

......
//其它构造函数最终都是调用这个函数创建MathStub对象
public MathStub(org.apache.axis2.context.ConfigurationContext configurationContext,java.lang.String targetEndpoint,boolean useSeparateListener)
		throws org.apache.axis2.AxisFault {
	populateAxisService();
	populateFaults();
	_serviceClient = new org.apache.axis2.client.ServiceClient(
			configurationContext,_service);
	_serviceClient.getOptions().setTo(
			new org.apache.axis2.addressing.EndpointReference(targetEndpoint));
	_serviceClient.getOptions().setUseSeparateListener(useSeparateListener);
	_serviceClient.getOptions().setSoapVersionURI(
			org.apache.axiom.soap.SOAP12Constants.SOAP_ENVELOPE_NAMESPACE_URI);
}
......
public com.sean.AddResponse add(com.sean.Add add0)
		throws java.rmi.RemoteException{
......
	// adding SOAP soap_headers
	_serviceClient.addHeadersToEnvelope(env);
......
}
......

看了下ServiceClient的源码：

......
private ArrayList<OMElement> headers;
......
public void addHeader(OMElement header) {
    if (headers == null) {
        headers = new ArrayList<OMElement>();
    }
    headers.add(header);
}

/**
 * Add SOAP Header to be sent with outgoing messages.
 *
 * @param header header to be sent (non-<code>null</code>)
 */
public void addHeader(SOAPHeaderBlock header) {
    if (headers == null) {
        headers = new ArrayList<OMElement>();
    }
    headers.add(header);
}

/** Remove all headers for outgoing message. */
public void removeHeaders() {
    if (headers != null) {
		headers.clear();
    }
}
	
public void addStringHeader(QName headerName,String headerText) throws AxisFault {
    if (headerName.getNamespaceURI() == null || 
			"".equals(headerName.getNamespaceURI())) {
        throw new AxisFault("Failed to add string header," 
				+ " you have to have namespaceURI for the QName");
    }
	OMElement omElement = OMAbstractFactory.getOMFactory()
			.createOMElement(headerName,null);
	omElement.setText(headerText);
	addHeader(omElement);
}

/**
 * Add all configured headers to a SOAP envelope.
 *
 * @param envelope the SOAPEnvelope in which to write the headers
 */
public void addHeadersToEnvelope(SOAPEnvelope envelope) {
	if (headers != null) {
        SOAPHeader soapHeader = envelope.getHeader();
		for (Object header : headers) {
            soapHeader.addChild((OMElement)header);
        }
    }
}
......

修改方式已经很明确了，在MathStub类中创建私有方法，通过AXIOM（使用版本为：1.2.14）生成所需头对象，然后将该头对象添加至ServiceClient对象即可

......
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.client.ServiceClient;
......
public MathStub(org.apache.axis2.context.ConfigurationContext configurationContext,_service);
	//添加SOAP头
	this.addHeaders(_serviceClient);
	_serviceClient.getOptions().setTo(
			new org.apache.axis2.addressing.EndpointReference(targetEndpoint));
	_serviceClient.getOptions().setUseSeparateListener(useSeparateListener);
	_serviceClient.getOptions().setSoapVersionURI(
			org.apache.axiom.soap.SOAP12Constants.SOAP_ENVELOPE_NAMESPACE_URI);
}
......
private void addHeaders(org.apache.axis2.client.ServiceClient _serviceClient){
	OMFactory omFactory = OMAbstractFactory.getOMFactory();
	OMNamespace omNS=omFactory.createOMNamespace("http://sean.com","sean");
	
	OMElement head = omFactory.createOMElement("Security",omNS);
	OMElement token = omFactory.createOMElement("Token",omNS);
	head.addChild(token);
		
	OMElement userName = omFactory.createOMElement("Username",omNS);
	userName.addChild(omFactory.createOMText(userName,"root"));
	token.addChild(userName);
		
	OMElement password = omFactory.createOMElement("Password",omNS);
	password.addAttribute(omFactory.createOMAttribute("Type",null,"PasswordText"));
	password.addChild(omFactory.createOMText(password,"123"));
	token.addChild(password);
		
	_serviceClient.addHeader(head);
}
......

添加SOAP头之前的请求格式如下：

<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
	<soapenv:Body>
		<ns1:add xmlns:ns1="http://sean.com">
			<ns1:x>1</ns1:x>
			<ns1:y>1</ns1:y>
		</ns1:add>
	</soapenv:Body>
</soapenv:Envelope>

添加SOAP头之后的请求格式如下：

<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
	<soapenv:Header>
		<sean:Security xmlns:sean="http://sean.com">
			<sean:Token>
				<sean:Username>root</sean:Username>
				<sean:Password Type="PasswordText">123</sean:Password>
			</sean:Token>
		</sean:Security>
	</soapenv:Header>
	<soapenv:Body>
		<ns1:add xmlns:ns1="http://sean.com">
			<ns1:x>1</ns1:x>
			<ns1:y>1</ns1:y>
		</ns1:add>
	</soapenv:Body>
</soapenv:Envelope>
