我有这样的代码:
private WSSecurityEngine engine = new WSSecurityEngine();
private CallbackHandler callbackHandler = new UsernamePasswordCallbackHandler();
@Test
public void testWss4jEngine() {
InputStream in = getClass().getClassLoader().getResourceAsStream("soap/soapWithUsernameTokenRequest.xml");
DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder;
Document doc = null;
try {
docBuilder = builderFactory.newDocumentBuilder();
doc = docBuilder.parse(in);
} catch (Exception e) {
LOG.error("Error parsing incoming request. Probably it is not a valid XML/SOAP message.", e);
return;
}
List<WSSecurityEngineResult> results = null;
try {
results = engine.processSecurityHeader(doc, null, callbackHandler, null);
} catch (WSSecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// the following line raises a NullPointerException
WSSecurityEngineResult actionResult = WSSecurityUtil.fetchActionResult(results, WSConstants.UT);
UsernameToken receivedToken = (UsernameToken) actionResult.get(WSSecurityEngineResult.TAG_USERNAME_TOKEN);
Assert.assertTrue(receivedToken != null);
}
传递给 WSS4j 引擎的文件中的 SOAP 消息是:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<tem:Add xmlns:tem="http://tempuri.org/">

在我看来,这是一个完全符合 WS-Security UsernameToken 的消息!
但是,engine.processSecurityHeader() 不返回任何安全结果。结果变量保持为空,然后在下一行引发 NPE。这是堆栈跟踪:
java.lang.NullPointerException

任何人都知道我做错了什么?
