我必须将用户凭据添加到标题中，所以我这样做了：
private void modifyRequest(String username, String password) {
UserCredentials authHeader = new UserCredentials();
authHeader.setUsername(username);
authHeader.setPassword(password);
ArrayList<Header> headers = new ArrayList<Header>(1);
try {
Header soapHeader = new Header(new QName(TQIntegrationV2.TQIntegrationV2Soap.getNamespaceURI(), "UserCredentials"), authHeader, new JAXBDataBinding(UserCredentials.class));
headers.add(soapHeader);
} catch (JAXBException ex) {
LOGGER.error("Exception trying to serialize header: {}", ex);
}
((BindingProvider) proxy).getRequestContext().put(Header.HEADER_LIST, headers);
}
一切正常。对 Web 服务的每次调用都带有传递给此标头的用户名和密码。您可以轻松地将其更改为适用于您的情况。
编辑
上面的代码是使用CXFAPI 来修改标头。我也使用JAX-WS. 它几乎相同，修改标头以添加用户凭据：
public class MyHandler implements SOAPHandler<SOAPMessageContext> {
private static final Logger LOGGER = LoggerFactory.getLogger(MyHandler.class);
private String username;
private String password;
/**
* Handles SOAP message. If SOAP header does not already exist, then method will created new SOAP header. The
* username and password is added to the header as the credentials to authenticate user. If no user credentials is
* specified every call to web service will fail.
*
* @param context SOAP message context to get SOAP message from
* @return true
*/
@Override
public boolean handleMessage(SOAPMessageContext context) {
try {
SOAPMessage message = context.getMessage();
SOAPHeader header = message.getSOAPHeader();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
if (header == null) {
header = envelope.addHeader();
}
QName qNameUserCredentials = new QName("https://your.target.namespace/", "UserCredentials");
SOAPHeaderElement userCredentials = header.addHeaderElement(qNameUserCredentials);
QName qNameUsername = new QName("https://your.target.namespace/", "Username");
SOAPHeaderElement username = header.addHeaderElement(qNameUsername );
username.addTextNode(this.username);
QName qNamePassword = new QName("https://your.target.namespace/", "Password");
SOAPHeaderElement password = header.addHeaderElement(qNamePassword);
password.addTextNode(this.password);
userCredentials.addChildElement(username);
userCredentials.addChildElement(password);
message.saveChanges();
//TODO: remove this writer when the testing is finished
StringWriter writer = new StringWriter();
message.writeTo(new StringOutputStream(writer));
LOGGER.debug("SOAP message: \n" + writer.toString());
} catch (SOAPException e) {
LOGGER.error("Error occurred while adding credentials to SOAP header.", e);
} catch (IOException e) {
LOGGER.error("Error occurred while writing message to output stream.", e);
}
return true;
}
//TODO: remove this class after testing is finished
private static class StringOutputStream extends OutputStream {
private StringWriter writer;
public StringOutputStream(StringWriter writer) {
this.writer = writer;
}
@Override
public void write(int b) throws IOException {
writer.write(b);
}
}
@Override
public boolean handleFault(SOAPMessageContext context) {
LOGGER.debug("handleFault has been invoked.");
return true;
}
@Override
public void close(MessageContext context) {
LOGGER.debug("close has been invoked.");
}
@Override
public Set<QName> getHeaders() {
LOGGER.debug("getHeaders has been invoked.");
return null;
}
public void setUsername(String username) {
this.username = username;
}
public void setPassword(String password) {
this.password = password;
}
}
我在这样的Spring配置中定义了这个处理程序：
<bean id="soapHandler" class="your.package.MyHandler">
<property name="username" value="testUser"/>
<property name="password" value="testPassword"/>
</bean>
<jaxws:client "...">
<jaxws:handlers>
<ref bean="soapHandler"/>
</jaxws:handlers>
</jaxws:client>
你需要做的就是实现SOAPHandler<SOAPMessageContext>接口，覆盖它的方法，然后你可以用消息做任何你想做的事情SOAP。
