Unable to convert payload of type <class-name> to byte[] for sending to Pub/Sub

I am trying to publish a message to Google Cloud PubSub using the library:
implementation "com.google.cloud:spring-cloud-gcp-starter-pubsub:2.0.0".
But, I am getting the below exception:
com.google.cloud.spring.pubsub.support.converter.PubSubMessageConversionException: Unable to convert payload of type com.logistics.domain.events.items.FOItemsReturnedTrackingUpdate to byte[] for sending to Pub/Sub.
Here is the full stack trace:
com.google.cloud.spring.pubsub.support.converter.PubSubMessageConversionException: Unable to convert payload of type com.logistics.domain.events.items.FOItemsReturnedTrackingUpdate to byte[] for sending to Pub/Sub.

Below is the code for publishing the event:
#Slf4j
#Component
public class ItemsReturnedTrackingUpdateEventPublisherPubSubAdapter implements
ItemsReturnedTrackingUpdateEventPublisher {
private final String topicName;
private final PubSubTemplate pubSubTemplate;
private final ObjectWriter objectWriter;
public ItemsReturnedTrackingUpdateEventPublisherPubSubAdapter(String topicName,
PubSubTemplate pubSubTemplate,
ObjectWriter objectWriter) {
this.topicName = topicName;
this.pubSubTemplate = pubSubTemplate;
this.objectWriter = objectWriter;
}
#Override
public void publishItemsReturnedTrackingUpdate(ItemsReturnedTrackingUpdate data) {
try {
Map<String, String> attributes = MDC.getCopyOfContextMap();
attributes.put("eventType", EventType.ITEMS_RETURNED_TRACKING_UPDATE.name());
var message = objectWriter.writeValueAsString(data);
log.debug("ItemsReturnedTrackingUpdate event is being published on topic : {} with attributes : {} and data : {}",
topicName, attributes, message);
ListenableFuture<String> result = pubSubTemplate.publish(topicName, data);
log.debug("ItemsReturnedTrackingUpdate published: {}, Message id: {}", data.getOrderId(), result.get());
} catch (Exception e) {
log.error("Error publishing ItemsReturnedTrackingUpdate with id: {}", data.getOrderId());
e.printStackTrace();
throw new PublisherException("Error publishing ItemsReturnedTrackingUpdate with id: " + data.getOrderId(), e);
}
}
}

You need to have a pubsub Message converter like below
#Bean
#Primary
public PubSubMessageConverter pubSubMessageConverter(ObjectMapper objectMapper) {
return new JacksonPubSubMessageConverter(objectMapper);
}
Also attaching sample example for object mapper bean
#Bean
#Primary
public ObjectMapper objectMapper() {
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
return mapper;
}

Looking at the stack trace, SimplePubSubMessageConverter is choking on the Object being published. Looking at the doc for that class:
... maps payloads of type byte[], ByteString, ByteBuffer, and String to Pub/Sub messages
Change:
pubSubTemplate.publish(topicName, data);
To:
pubSubTemplate.publish(topicName, message);

Catching ValidationException instead of a custom Exception in ControllerAdvice

I'm trying to throw an exception inside a custom validator which I built using annotation like that:
ValidExtractionDate annotation:
#Constraint(validatedBy = ExtractionDateValidator.class)
#Target( { ElementType.PARAMETER })
#Retention(RetentionPolicy.RUNTIME)
public #interface ValidExtractionDate {
String message() default "Invalid value for extractionDate";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
ExtractionDateValidator:
public class ExtractionDateValidator implements ConstraintValidator<ValidExtractionDate, LocalDate> {
#Override
public void initialize(ValidExtractionDate constraintAnnotation) {
ConstraintValidator.super.initialize(constraintAnnotation);
}
#Override
public boolean isValid(LocalDate localDate, ConstraintValidatorContext constraintValidatorContext) {
if (localDate.isAfter(LocalDate.now())) {
throw new InvalidExtractionDateException("date is set in the future");
}
return true;
}
}
as you see above, an exception of type InvalidExtractionDateException is thrown when localDate is invalid:
InvalidExtractionDateException:
public class InvalidExtractionDateException extends ValidationException {
public InvalidExtractionDateException(String message) {
super(message);
}
}
Inside my ControllerAdvice I have this:
/**
* #param ex a Exception
* #return a responseEntity with a descriptive message and some other information
*/
#ExceptionHandler(Exception.class)
#ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
#ResponseBody
public ErrorMessage globalExceptionHandler(Exception ex) {
LOG.error(ex.getClass().getName());
ex.printStackTrace();
LOG.error(ex.getMessage());
return getErrorMessage();
}
/**
* #param ex an InvalidExtractionDateException exception
* #return a responseEntity with a descriptive message and some other information
*/
#ExceptionHandler(InvalidExtractionDateException.class)
#ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
#ResponseBody
public ErrorMessage invalidExtractionDateException(InvalidExtractionDateException ex) {
LOG.error(ex.getMessage());
return getErrorMessage(ex, ErrorCode.INVALID_INPUT_ERROR);
}
Unfortunately after throwing the exception, the AdviceController is calling for globalExceptionHandler() method instead of invalidExtractionDateException() method.
This is what I get on the console:

Please advise what is wrong in my code. Thanks in advance.
Also can i ask if there any recommendation ways to encrypt the data value obtained from api before added into the database.

You need to add #Autowired to bankCitiBankDAO too:
#Autowired
private BankOCBCDAO bankOCBCDAO;
#Autowired
private BankCitiBankDAO bankCitiBankDAO;
But as field injection is not the best thing todo (https://www.vojtechruzicka.com/field-dependency-injection-considered-harmful/), you should go with constructor injection:
#Service
public class PaymentServiceImpl implements PaymentService{
private BankOCBCDAO bankOCBCDAO;
private BankCitiBankDAO bankCitiBankDAO;
public PaymentServiceImpl(BankOCBCDAO bankOCBCDAO, BankCitiBankDAO bankCitiBankDAO){
this.bankOCBCDAO = bankOCBCDAO;
this.bankCitiBankDAO = bankCitiBankDAO;
}
...
}

Please add the Proper Annotations in Model Class
that will clear the issues.
Reference
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="bank_id")
private int bankId;

How do i create a reference in firebase using the java native SDK

I'm trying to create a reference inside of my firebase by using the Java native SDK. Does anyone know how to do this?
This is what I have currently tried:
Firstly, I have this class. The attribute that is supposed to be the reference is soat.
public class Car {
private String plate;
private String model;
private long km;
private boolean available;
private DocumentReference soat;
}
This is the code I use to save document to Firestore:
public void save(Car car) {
Map<String, Object> data = new HashMap<>();
DocumentReference soatRef = fb.getFirestore().collection("SOATS").document(car.getPlate());
data.put("plate", car.getPlate() );
data.put("model", car.getModel());
data.put("km", car.getKm());
data.put("available", car.isAvailable());
data.put("soat", soatRef);
fb.getFirestore().collection("Cars").document(car.getPlate()).set(data);
}
This is the code I use to read objects from Firestore:
public List<Car> findAll() {
List<Car> empList = new ArrayList<Car>();
CollectionReference car = fb.getFirestore().collection("Cars");
ApiFuture<QuerySnapshot> querySnapshot = car.get();
try {
for (DocumentSnapshot doc : querySnapshot.get().getDocuments()) {
Car emp = doc.toObject(Car.class);
empList.add(emp);
}
} catch (Exception e) {
e.printStackTrace();
}
return empList;
}
But I'm having this exception showing up:
There was an unexpected error (type=Internal Server Error, status=500).

How to use Future<T> to get a AsyncResult<T> as return?

The inheritance relationship is as follow:
class AsyncResult<V> implements ListenableFuture<V>
interface ListenableFuture<T> extends Future<T>
interface Future<T>
I use AsyncResult as follow:
#Async
public AsyncResult<Integer> asyncMul10(int base){
base = base * 10;
return new AsyncResult<>(base);
}
And get asyncMul10() by follow:
Future<Integer> future10 =asyncHandle.asyncMul10(base);
It will thow exception while run over this line.
java.lang.ClassCastException: org.springframework.util.concurrent.ListenableFutureTask cannot be cast to org.springframework.scheduling.annotation.AsyncResult
I don't understand why the child class cannot be converted into the parent class.
All codes here:
MainServiceImpl Service:
#Service
public class MainServiceImpl implements IMainService {
#Autowired
private IAsyncHandle asyncHandle;
#Override
public String async(int base) throws InterruptedException, ExecutionException {
Integer mul10;
Future<Integer> future10 =asyncHandle.asyncMul10(base);
while (true){
if(future10.isDone()){
mul10=future10.get();
break;
}
}
return "Mul 10 = "+mul10;
}
}
IAsyncHandle Interface:
public interface IAsyncHandle {
AsyncResult<Integer> asyncMul10(int base) throws InterruptedException;
}
AsyncHandleImpl Component class
#Component
public class AsyncHandleImpl implements IAsyncHandle {
#Override
#Async
public AsyncResult<Integer> asyncMul10(int base){
base = base * 10;
return new AsyncResult<>(base);
}
}
Exception stack trace as follow:
java.lang.ClassCastException: org.springframework.util.concurrent.ListenableFutureTask cannot be cast to org.springframework.scheduling.annotation.AsyncResult

BTW,
at cn.zora.springdemo.service.impl.MainServiceImpl.async(MainServiceImpl.java:33) ~[classes/:na]
is
Future<Integer> future10 =asyncHandle.asyncMul10(base);

the issue is in this line of code
#Async
public AsyncResult<Integer> asyncMul10(int base){
base = base * 10;
return new AsyncResult<>(base);
}
change the return type from AsyncResult to Future and it should fix the issue
#Async
public Future<Integer> asyncMul10(int base){
base = base * 10;
return new AsyncResult<>(base);
}
