I have a class generated with JAXB2 form a WSDL. The elements defined in the WSDL are NOT declared as XmlRootElement.
#Service
public class ProblemService extends WebServiceGatewaySupport {
public ProblemResponse addProblem(final Problem problem, final String aNumber) {
final String namespacePrefix = "soapenv";
final String action = "Problem";
final ObjectFactory factory = new ObjectFactory();
final JAXBElement<Problem> request = factory.createProblem(problem);
try {
StringResult result = new StringResult();
getMarshaller().marshal(request, result);
System.out.println(result.toString());
} catch (Exception e) {
e.printStackTrace(System.err);
}
final WebServiceTemplate wst = this.getWebServiceTemplate();
#SuppressWarnings("unchecked")
final JAXBElement<ProblemResponse> response = (JAXBElement<ProblemResponse>) wst
.marshalSendAndReceive(abcConfiguration.getEndpoint(), request, new WebServiceMessageCallback() {
#Override
public void doWithMessage(final WebServiceMessage message) {
try {
prepareSoapHeader(message, namespacePrefix, action);
final SaajSoapMessage ssMessage = (SaajSoapMessage) message;
final SOAPEnvelope envelope = ssMessage.getSaajMessage().getSOAPPart().getEnvelope();
envelope.getBody().setPrefix(namespacePrefix);
final NodeList nl = ssMessage.getSaajMessage().getSOAPPart().getEnvelope().getBody().getChildNodes();
ssMessage.getSaajMessage().getSOAPPart().getEnvelope().getBody().removeChild(nl.item(0));
final SOAPElement se = ssMessage.getSaajMessage().getSOAPPart().getEnvelope().getBody()
.addBodyElement(new QName(action));
se.setPrefix(NAMESPACE_PREFIX_V2);
addUserAuthentification(se);
try {
StringResult result = new StringResult();
getAbcConfiguration().marshaller().marshal(request, result);
System.out.println(result.toString());
} catch (Exception e) {
e.printStackTrace(System.err);
}
System.out.println();
} catch (SoapFaultClientException e) {
logger.error("Error on client side during marshalling of the SOAP request for {}.", action, e);
} catch (SOAPException e) {
logger.error("Error during marshalling of the SOAP request for {}.", action, e);
}
}
});
return response.getValue();
}
}
The generated StringResult looks quiet good but I need to replace some parts in the resulting XML (for instance the prefix) and I need to add some stuff into the SoapBody which are not part of the base class (Problem) before sending the SOAP request to the remote service.
Furthermore I want to modify the header part of the envelope...
How can I achieve this? My application is a SpringBoot application and in the configuration class being used in my service the un-/marshaller are defined this way:
#Bean
public Jaxb2Marshaller marshaller() {
final Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
//setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.setContextPath(contextPath);
//marshaller.afterPropertiesSet();
marshaller.setMarshallerProperties(new HashMap<String, Object>() {{
put(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, true);
}});
return marshaller;
}
#Bean
public ProblemService problemService(final Jaxb2Marshaller marshaller) throws Exception {
final ProblemService client = new ProblemService();
client.setDefaultUri(this.endpoint);
client.setMarshaller(marshaller);
client.setUnmarshaller(marshaller);
final HttpsUrlConnectionMessageSender msgSender = new HttpsUrlConnectionMessageSender();
client.setMessageSenders(new WebServiceMessageSender[] {msgSender, httpComponentsMessageSender()});
//client.setMessageSender(msgSender);
return client;
}
With this little piece of code I was able to add information to the SoapBody as demanded:
try {
getKpmConfiguration().marshaller().marshal(request, ssMessage.getPayloadResult());
ssMessage. writeTo(System.out);
} catch (/*JAXB*/Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

Below is my application class. The flow is like the DEToken class from here and from DEToken I call RestConnection where I have the #retryable method.

}
Considering you see your function restPost() implementation,
#Retryable(value = {IOException.class, ConnectException.class},
maxAttempts = 4,
backoff = #Backoff(5000))
public StringBuffer restPost(String restUrl, String payload) {
try {
// Your code
}
catch(IOException ex){ // These catch block handles the exception
// and nothing to throw to retryable.
}
catch(MalformedURLException ex){ // More catch blocks that you
// define to handle exception.
}
}
Here you handle all of the exceptions that can be a cause to revoke the retry and recover methods.
Note: Recoverable methods only execute when a exception is thrown, not handled by any try-catch block.
Whatever exception is raised by method restPost() is handled by the method try-catch block itself and there are no exceptions that had been rethrow by a catch block.
Now, Spring-Retry is unable to get any exception (because it is handled by the method try-catch block). So, no recovery method will be executed.
Solution: you should remove those catch blocks from the method definition on which you want to perform retry or recover.
Please do the needful and it will work like a charm... :)
I am required to develop Web Service using the Spring Framework.
Scenario is like this:
My program will send a SOAP request (header + payload) to a service and expects a response (header + payload) back from the service.
Both the payload and header are important and needed by the program.
Problem is that I am unable to find any example in Spring WS where both header and payload are sent as part of request and header and payload extracted from response.
I am using WebServiceGatewaySupport and WebServiceTemplate for sending of request and fetching of response.
WebServiceTemplate provides 2 methods for sending request:
marshalSendAndReceive
sendAndReceive
Problem with marshalSendAndReceive is that I will not get back the response header though I can send the request header.
Problem with sendAndReceive is that I will not be able to send the request header though I will be able to extract the response header.
The only solution currently available right now is to use Interceptors but it seems that this is not the proper way of handling the headers as header is intercepted before it reaches the calling function. To have the calling function access to response header, we will need to make the Interceptor as stateful which is not desirable.
I will really appreciate guidance and help from anyone who can provide me with an example of how to properly achieve this.
Please find my code below when using sendAndReceive:
public class ClientAccountInformation extends WebServiceGatewaySupport {
public ClientAccountInformation() {
}
public FIGetAcctsInfoCallBackRs sendRequest(GetAcctInfoRq request, HeaderRq headerRq) {
WebServiceTemplate webServiceTemplate = getWebServiceTemplate();
try {
ResponseAndHeader responseAndHeader = webServiceTemplate.sendAndReceive(Constants.WEBSERVICE_URL,
new WebServiceMessageCallback() {
public void doWithMessage(WebServiceMessage message) throws IOException {
try {
Jaxb2Marshaller marshallerRq = new Jaxb2Marshaller();
marshallerRq.setContextPath("com.abc.domain..getacctinfo");
marshallerRq.afterPropertiesSet();
MarshallingUtils.marshal(marshallerRq, request, message);
SoapHeader soapHeader = ((SoapMessage)message).getSoapHeader();
JAXBContext context = JAXBContext.newInstance(HeaderRq.class);
Marshaller marshaller = context.createMarshaller();
marshaller.marshal(HeaderRq, soapHeader.getResult());
} catch (Exception e) {
e.printStackTrace();
}
}
},
new WebServiceMessageExtractor<ResponseAndHeader>() {
public ResponseAndHeader extractData(WebServiceMessage message) throws IOException {
SoapHeader header = ((SoapMessage)message).getSoapHeader();
Iterator<SoapHeaderElement> it = header.examineHeaderElements(new QName("urn:test", "HeaderRs"));
return new ResponseAndHeader(
it.hasNext() ? (HeaderRs)jaxb2Marshaller().unmarshal(it.next().getSource())
: null,
(GetAcctInfoRs) MarshallingUtils.unmarshal(jaxb2Marshaller(), message));
}
});
return null;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
Jaxb2Marshaller jaxb2Marshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPath("com.abc.domain.getacctinfo");
return jaxb2Marshaller;
}
}
The above code always returns null for the response header.
I have solved the issue. I can send the SOAP header to a service and extract the response header from response also. No need for interceptors.
Main help was from blog post from Andreas Veithen. Thanks.

I have already created an e mail confirmation in spring boot it is working nicely, and also I created a link when a user click it should say "confirmed"but I did not figure it out how to do that?
E mail sender java class:
#Component
public class EmailSender {
#Autowired
JavaMailSender javaEmailSender;
public void sendEmail(String to, String subject, String text) throws MessagingException {
MimeMessage message = javaEmailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message,
MimeMessageHelper.MULTIPART_MODE_MIXED_RELATED,
StandardCharsets.UTF_8.name());
helper.setTo(to);
helper.setSubject(subject);
helper.setText(text, true);
helper.addInline("logo.jpg", new ClassPathResource("./images/logo.jpg"));
javaEmailSender.send(message);
}
}
E mail template Loader:
#Component
public class EmailTemplateLoader {
#Autowired
private Configuration freemakerConfiguration;
public String getEmailBody(String name, String confirmationLink) throws TemplateException {
try {
Template template = freemakerConfiguration.getTemplate("EmailConfirmation.ftl");
Map<String, Object> data = new HashMap<String, Object>();
data.put("name", name);
data.put("confirmationLink", confirmationLink);
return FreeMarkerTemplateUtils.processTemplateIntoString(template, data);
} catch (IOException e) {
e.printStackTrace();
} catch (TemplateException e) {
e.printStackTrace();
}
return "";
}
}
My signup Resource :
#Autowired
private SignupService signupService;
#Autowired
private HttpServletRequest httpServletRequest;
#RequestMapping(value = "user/signup", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
#Transactional(rollbackFor = Exception.class)
public ResponseEntity<?> signup(#RequestBody UserType user) throws SignUpException {
URL requestUrl = null;
try {
requestUrl = new URL(httpServletRequest.getRequestURL().toString());
} catch (MalformedURLException e) {
logger.debug("Malformed Request Url");
}
logger.debug(requestUrl.toString());
signupService.signUp(user, requestUrl.getHost());
return new ResponseEntity<>(HttpStatus.OK);
}
#RequestMapping(value = "user/confirmation", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
#Transactional(rollbackFor = Exception.class)
public ResponseEntity<?> confirmSignUp(#RequestParam("u") String loginName, #RequestParam("p") String token) {
try {
signupService.emailConfirmation(loginName, token);
return new ResponseEntity<>(HttpStatus.OK);
} catch (SignUpException e) {
return new ResponseEntity<>(e.getMessage(), HttpStatus.BAD_REQUEST);
}
}
So, As I told I can send an email successfully, but I could not sort how I can write confirmation successfully
Is it possible to have an implementation of a message splitter that can return an Iterator AND add custom header information?
For instance if I have the following class
public class CsvFileToIteratorSplitter extends AbstractMessageSplitter {
#Override
protected Object splitMessage(Message<?> message) {
Object payload = message.getPayload();
Assert.isInstanceOf(File.class, payload, "Expected java.io.File in the message payload");
try {
InputStream source = new FileInputStream((File) payload);
BufferedReader reader = new BufferedReader(new InputStreamReader(source));
String header = reader.lines().findFirst().orElse(null);
return MessageBuilder.withPayload(reader.lines().iterator())
.setHeaderIfAbsent("HEADER", header)
.build();
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
}
Then I can add to the header but the payload is actually an instance of Iterator and the split fails
If I modify so that the class is now
public class CsvFileToIteratorSplitter extends AbstractMessageSplitter {
#Override
protected Object splitMessage(Message<?> message) {
log.debug("{}", message.toString());
Object payload = message.getPayload();
Assert.isInstanceOf(File.class, payload, "Expected java.io.File in the message payload");
try {
InputStream source = new FileInputStream((File) payload);
BufferedReader reader = new BufferedReader(new InputStreamReader(source));
return reader.lines().iterator();
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
}
The split works but I lose the header info.
Is there any way to have a functioning split with the ability to add to the header?
You should return an Iterator<MessageBuilder<String>> ...

}
};
}

try {
InputStream source = new FileInputStream((File) payload);
final BufferedReader reader = new BufferedReader(new InputStreamReader(source));
final String header = reader.lines().findFirst().orElse(null);
final Iterator<String> iterator = reader.lines().iterator();
Iterator<MessageBuilder<String>> builderIterator = new Iterator<MessageBuilder<String>>() {
private String next;
#Override
public boolean hasNext() {
if (this.next != null) { // handle multiple hasNext() calls.
return true;
}
if (!iterator.hasNext()) {
try {
reader.close();
}
catch (IOException e) {
e.printStackTrace();
}
return false;
}
else {
this.next = iterator.next();
// Handle empty last line
if (next.length() == 0 && !iterator.hasNext()) {
try {
reader.close();
}
catch (IOException e) {
e.printStackTrace();
}
return false;
}
return true;
}
}
#Override
public MessageBuilder<String> next() {
String line = this.next;
this.next = null;
return MessageBuilder
.withPayload(line).setHeaderIfAbsent("HEADER", header);
}
};
return builderIterator;
}
catch (IOException e) {
throw new UncheckedIOException(e);
}
}
}

Note that your skip(1) is incorrect, since the first line has already been consumed from the reader.

foo,bar
baz.qux

I am Spring MVC beginner and I want to call rest in #ResponseBody. My external node server doesn't react on that method. I don't got message about request in my server console. Without UserRest it works. I would be grateful for your help
#Controller
public class AjaxController {
#RequestMapping(value= "user", method=RequestMethod.GET)
public #ResponseBody String login (){
UserRest ur = new UserRest();
Response r = ur.getUserName(2);
Gson gs = new Gson();
String str = gs.toJson(r);
return str;
}
}
Response getUserName(int userID){
Response response = new Response();
StringBuilder total = new StringBuilder();
try {
URL url = new URL(Properties.SERVER_SECURE_URL + "users/" + userID);
urlConnection = (HttpsURLConnection) url.openConnection();
urlConnection.setDoOutput(false);
urlConnection.setDoInput(true);
urlConnection.setRequestMethod("GET");
urlConnection.setRequestProperty("Authorization","1Strajk");
response.setMessageCode(urlConnection.getResponseCode());
if(response.getMessageCode()==Response.MESSAGE_OK) {
InputStream in = urlConnection.getInputStream();
BufferedReader r = new BufferedReader(new InputStreamReader(in));
String line;
while ((line = r.readLine()) != null) {
total.append(line);
}
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if(!total.toString().isEmpty()){
response.setObject(total.toString());
}
urlConnection.disconnect();
}
return response;
}
I resolve it. I forgot about SSL connection. Before calling rest I called that method:
public class SSLUtils {
public static void trustEveryone() {
try {
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, new X509TrustManager[]{new X509TrustManager(){
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {}
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}}}, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(
context.getSocketFactory());
} catch (Exception e) { // should never happen
e.printStackTrace();
}
}
}
