I am new to springboot where i m wrong. Help me.
I think problem with your Controller configuration.
try this
#RestController
public class ImgContr {
instead of
#Controller
public class ImgContr {
For more in-depth details please follow >> Controller vs RestController
Note : Above solution works when you need a json response not a solution for Spring-mvc Projects.

I have a doubt about how to pass more data to throw an exception, I want to pass more data at the time of launching it, to put that data in the service response ..
I have an exception handler class labeled #ControllerAdvice in spring, but I don't know the best way to pass the data.
This is the code I have
throw new OcspException("Exception OCSP");
public class OcspException extends RuntimeException {
private static final long serialVersionUID = 1L;
public OcspException(String businessMessage) {
super(businessMessage);
}
public OcspException(String businessMessage, Throwable throwable) {
super(businessMessage, throwable);
}
}
#ExceptionHandler(OcspException.class)
public ResponseEntity<Object> exception(OcspException exception,HttpServletRequest request) {
ResponseException response = new ResponseException();
response.setCode("404");
return new ResponseEntity<>(response, HttpStatus.NOT_FOUND);
}
I have the idea to do it, but I don't know if it is a good practice ... in the OcspException class to create attributes with their setter and getters, and create the constructor that receives this data, to then extract the data in exception controller
throw new OcspException("Exception OCSP","Hello");
public class OcspException extends RuntimeException {
private static final long serialVersionUID = 1L;
private String m;
public OcspException(String businessMessage) {
super(businessMessage);
}
public OcspException(String businessMessage, Throwable throwable) {
super(businessMessage, throwable);
}
public OcspException(String businessMessage, String message) {
super(businessMessage);
setM(message);
}
public String getM() {
return m;
}
public void setM(String m) {
this.m = m;
}
}
#ExceptionHandler(OcspException.class)
public ResponseEntity<Object> exception(OcspException exception,HttpServletRequest request) {
ResponseException response = new ResponseException();
response.setCode("404");
response.setDetails(exception.getM() );
return new ResponseEntity<>(response, HttpStatus.NOT_FOUND);
}
Try making an model called ErrorDetails which will hold a timestamp, message, and details.
It may look like this:
#Data
#Builder
#AllArgsConstructor
#NoArgsConstructor
public class ErrorDetails {
private LocalDateTime timeStamp;
private String message;
private String details;
}
Here's a sample of what my custom exceptions usually look like:
#Data
#ResponseStatus(value = HttpStatus.NOT_FOUND)
public class OrderNotFoundException extends RuntimeException {
private final String message;
public OrderNotFoundException(String message) {
super(message);
this.message = message;
}
}
Then for the #ExceptionHandler:
#ExceptionHandler(OrderNotFoundException.class)
public ResponseEntity<ErrorDetails>
orderNotFoundException(OrderNotFoundException ex, WebRequest request) {
ErrorDetails errorDetails = ErrorDetails.builder()
.timeStamp(LocalDateTime.now())
.message(ex.getMessage())
.details(request.getDescription(false))
.build();
return new ResponseEntity<>(errorDetails, HttpStatus.NOT_FOUND);
}
The error response for an order not found ends up being this:
{
"timeStamp": "2019-10-07T21:31:37.186",
"message": "Order with id 70 was not found.",
"details": "uri=/api/v1/order"
}
This way you can add whatever extra details in the ErrorDetails object. I hope that helps!
I have a Springboot Rest application having a server custom validator for one of the model. There are 2 api endpoints, one receives single object which other receives list of same object. My custom validator works fine on first endpoint. How can i use same validator for other endpoint.
Model class
#Entity
#Table(name=TABLE_MESSAGE, schema = SCHEMA)
public class Message implements java.io.Serializable {
#Id #GeneratedValue(strategy=IDENTITY)
#Column(name=COLUMN_ID, unique=true)
private Long id;
#Basic(optional = false)
#Column(name = COLUMN_CREATETIMESTAMP, insertable = false, updatable = false)
#Temporal(TemporalType.TIMESTAMP)
private Date timestamp;
#Column(name=COLUMN_MESSAGE_SENDERNAME)
private String senderName;
#Column(name=COLUMN_MESSAGE_SENDEREMAIL)
private String senderEmail;
#Column(name=COLUMN_MESSAGE_SUBJECT)
private String subject;
#Column(name=COLUMN_MESSAGE_BODY)
private String body;
}
DTO class
public class MessageForm {
private List<Message> messageList;
public List<Message> getMessageList() {
return messageList;
}
public void setMessageList(List<Message> messageList) {
this.messageList = messageList;
}
}
Custom validator
#Component
public class MessageValidator implements Validator {
#Override
public boolean supports(Class<?> clazz) {
return Message.class.equals(clazz);
}
#Override
public void validate(Object target, Errors errors) {
ValidationUtils.rejectIfEmpty(errors, "senderName", ERRORCODE_MESSAGE_SENDERNAME_EMPTY);
ValidationUtils.rejectIfEmpty(errors, "senderEmail", ERRORCODE_MESSAGE_SENDEREMAIL_EMPTY);
ValidationUtils.rejectIfEmpty(errors, "subject", ERRORCODE_MESSAGE_SUBJECT_EMPTY);
ValidationUtils.rejectIfEmpty(errors, "body", ERRORCODE_MESSAGE_BODY_EMPTY);
Message m = (Message) target;
if (!m.getSenderName().trim().equalsIgnoreCase(EMPTY_STRING) && m.getSenderName().matches(REGEX_CONTAINS_NUMBER)) {
errors.rejectValue("senderName", ERRORCODE_MESSAGE_SENDERNAME_INVALID);
}
if (!m.getSenderEmail().trim().equalsIgnoreCase(EMPTY_STRING) && !m.getSenderEmail().matches( REGEX_EMAIL)) {
errors.rejectValue("senderEmail", ERRORCODE_MESSAGE_SENDEREMAIL_INVALID);
}
}
}
Controller
#RestController
public class MainSiteRestController
{
#Autowired
private MessageValidator messageValidator;
#InitBinder("message")
protected void initMessageBinder(WebDataBinder binder) {
binder.addValidators(messageValidator);
}
// this works fine
public ResponseForm saveMessage(#Valid #RequestBody Message message, BindingResult bindingResult) throws APIException {
if (bindingResult.hasErrors()){
throw new APIException(getErrorMesage(bindingResult.getAllErrors()));
}
return apiService.saveMessage(message);
}
// this is not working
public ResponseForm saveAllMessage(#RequestBody MessageForm messageForm, Errors errors) throws APIException {
// need to validate the complete list or particular indexed object here, tried below code but not working
// messageValidator.validate(messageForm.getMessageList().get(0), errors);
if(errors.hasErrors()) {
throw new APIException(createErrorString(errors));
}
return apiService.saveAllMessage(messageForm);
}
}
Spring validators work on a single form, therefore you will have to create a validator for list dto.
I am running a Spring Boot application with a PostConstruct method to populate a POJO before application initialization. This is to ensure that the database isn't hit by multiple requests to get the POJO content after it starts running.
I'm able to pull the data from Oracle database through Hibernate query and store it in my POJO. The problem arises when I try to access the stored data. The dataset contains a list of objects that contain strings and numbers. Just trying to print the description of the object at the top of the list raises a class cast exception. How should I mitigate this issue?
#Autowired
private TaskDescrBean taskBean;
#PostConstruct
public void loadDescriptions() {
TaskDataLoader taskData = new TaskDataLoader(taskBean.acquireDataSourceParams());
List<TaskDescription> taskList = tdf.getTaskDescription();
taskBean.setTaskDescriptionList(taskList);
System.out.println("Task description size: " + taskBean.getTaskDescriptionList().get(0).getTaskDescription());
}
My POJO class:
#Component
public class TaskDescrBean implements ApplicationContextAware {
#Resource
private Environment environment;
protected List<TaskDescription> taskDescriptionList;
public Properties acquireDataSourceParams() {
Properties dataSource = new Properties();
dataSource.setProperty("hibernate.connection.driver_class", environment.getProperty("spring.datasource.driver-class-name"));
dataSource.setProperty("hibernate.connection.url", environment.getProperty("spring.datasource.url"));
dataSource.setProperty("hibernate.connection.username", environment.getProperty("spring.datasource.username"));
dataSource.setProperty("hibernate.connection.password", environment.getProperty("spring.datasource.password"));
return dataSource;
}
public List<TaskDescription> getTaskDescriptionList() {
return taskDescriptionList;
}
public void setTaskDescriptionList(List<TaskDescription> taskDescriptionList) {
this.taskDescriptionList = taskDescriptionList;
}
public ApplicationContext getApplicationContext() {
return applicationContext;
}
public void setApplicationContext(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
}
My DAO class:
public class TaskDataLoader {
private Session session;
private SessionFactory sessionFactory;
public TaskDataLoader(Properties connectionProperties) {
Configuration config = new Configuration().setProperties(connectionProperties);
config.addAnnotatedClass(TaskDescription.class);
sessionFactory = config.buildSessionFactory();
}
#SuppressWarnings("unchecked")
public List<TaskDescription> getTaskDescription() {
List<TaskDescription> taskList = null;
session = sessionFactory.openSession();
try {
String description = "from TaskDescription des";
Query taskDescriptionQuery = session.createQuery(description);
taskList = taskDescriptionQuery.list();
System.out.println("Task description fetched. " + taskList.getClass());
} catch (Exception e) {
e.printStackTrace();
} finally {
session.close();
}
return taskList;
}
TaskDescription Entity:
#Entity
#Table(name="TASK_DESCRIPTION")
#JsonIgnoreProperties
public class TaskDescription implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Column(name="TASK_DESCRIPTION_ID")
private Long taskDescriptionId;
#Column(name="TASK_DESCRIPTION")
private String taskDescription;
public Long getTaskDescriptionId() {
return taskDescriptionId;
}
public void setTaskDescriptionId(Long taskDescriptionId) {
this.taskDescriptionId = taskDescriptionId;
}
public String getTaskDescription() {
return taskDescription;
}
public void setTaskDescription(String taskDescription) {
this.taskDescription = taskDescription;
}
}

Instead of sending the List in the return statement, I transformed it into a JSON object and sent its String representation which I mapped back to the Object after transforming it using mapper.readValue()
I'm trying to test some services with Mockito but I have problems when the main class that I test and where I inject Mocks calls to super.
I run the project with spring and these are the steps I follow to get the error.
Here is where I create the test
public class UrlShortenerTests {
private MockMvc mockMvc;
#Mock
private ShortURLRepository shortURLRepository;
#Mock
private ClickRepository clickRespository;
#InjectMocks
private UrlShortenerControllerWithLogs urlShortenerWL;
#Before
public void setup() {
MockitoAnnotations.initMocks(this);
this.mockMvc = MockMvcBuilders.standaloneSetup(urlShortenerWL).build();
}
#Test
public void thatShortenerCreatesARedirectIfTheURLisOK() throws Exception {
mockMvc.perform(post("/link")
.param("url", "http://www.google.com"))
.andDo(print())
.andExpect(status().isCreated())
.andExpect(jsonPath("$.target", is("http://example.com/")));
}
}
Here is the class UrlShortenerControllerWithLogs with the method shortener, which is the one I want to test with the previous POST call
#RestController
public class UrlShortenerControllerWithLogs extends UrlShortenerController {
#Autowired
private ClickRepository clickRepository;
#Autowired
private ShortURLRepository SURLR;
public ResponseEntity<ShortURL> shortener(#RequestParam("url") String url,
#RequestParam(value = "sponsor", required = false) String sponsor,
#RequestParam(value = "brand", required = false) String brand,
HttpServletRequest request) {
ResponseEntity<ShortURL> su = super.shortener(url, sponsor, brand,
request);
return su;
}
And this is the super class
#RestController
public class UrlShortenerController {
#Autowired
protected ShortURLRepository shortURLRepository;
#Autowired
protected ClickRepository clickRepository;
#RequestMapping(value = "/link", method = RequestMethod.POST)
public ResponseEntity<ShortURL> shortener(#RequestParam("url") String url,
#RequestParam(value = "sponsor", required = false) String sponsor,
#RequestParam(value = "brand", required = false) String brand,
HttpServletRequest request) {
ShortURL su = createAndSaveIfValid(url, sponsor, brand, UUID
.randomUUID().toString(), extractIP(request));
if (su != null) {
HttpHeaders h = new HttpHeaders();
h.setLocation(su.getUri());
return new ResponseEntity<>(su, h, HttpStatus.CREATED);
} else {
return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
}
}
protected ShortURL createAndSaveIfValid(String url, String sponsor,
String brand, String owner, String ip) {
UrlValidator urlValidator = new UrlValidator(new String[] { "http",
"https" });
if (urlValidator.isValid(url)) {
String id = Hashing.murmur3_32()
.hashString(url, StandardCharsets.UTF_8).toString();
ShortURL su = new ShortURL(id, url,
linkTo(
methodOn(UrlShortenerController.class).redirectTo(
id, null)).toUri(), sponsor, new Date(
System.currentTimeMillis()), owner,
HttpStatus.TEMPORARY_REDIRECT.value(), true, ip, null);
return shortURLRepository.save(su);
} else {
return null;
}
}
So, when I call to shortURLRepository.save(su) in the second method (createAndSaveIfValid), it never enters in the method save, so it returns me null instead of the object I want.
The code of the implementation of ShortURLRepository and the method save is:
#Repository
public class ShortURLRepositoryImpl implements ShortURLRepository {
private static final Logger log = LoggerFactory
.getLogger(ShortURLRepositoryImpl.class);
#Override
public ShortURL save(ShortURL su) {
try {
jdbc.update("INSERT INTO shorturl VALUES (?,?,?,?,?,?,?,?,?)",
su.getHash(), su.getTarget(), su.getSponsor(),
su.getCreated(), su.getOwner(), su.getMode(), su.getSafe(),
su.getIP(), su.getCountry());
} catch (DuplicateKeyException e) {
log.debug("When insert for key " + su.getHash(), e);
return su;
} catch (Exception e) {
log.debug("When insert", e);
return null;
}
return su;
}
I think that the problem is that the object ShortURLRepository created in the test class is not initialized on the super class (UrlShortenerController) or something similar.
Is it possible?
Can anybody help me?

This is not an error. This is the expected behaviour. #Mock creates a mock. #InjectMocks creates an instance of the class and injects the mocks that are created with the #Mock. A mock is not a real object with known values and methods. It is an object that has the same interface as the declared type but you control its behaviour. By default the mocked object methods do nothing (e.g. return null). Therefore if ShortURLRepository is mocked and injected in UrlShortenerControllerWithLogs calling save in the injected ShortURLRepository does not call the real code as you expected, it does nothing. If you want to mock the behaviour of save, add the following code in your setup:
when(shortURLRepository.save(org.mockito.Matchers.any(ShortURL.class))).
then(new Answer<ShortURL>() {
#Override
public ShortURL answer(InvocationOnMock invocation) throws Throwable {
ShortURL su = (ShortURL) invocation.getArguments()[0];
// Do something with su if needed
return su;
}
});
We are trying to use autowiring in our webservice, but this doens't seem to work (generates nullPointer). We have been searching for a solution for quite a long time, but did not succeed.
Our webservice:
#WebService(wsdlLocation = "/WEB-INF/wsdl/contract.wsdl", serviceName = "BookingService", targetNamespace = "http://realdolmen.com/", portName = "BookingServicePortType")
public class BookingService extends SpringBeanAutowiringSupport implements BookingServicePortType {
#Autowired
BookingServiceBean bookingServiceBean;
#Autowired
TariffService tariffService;
#Override
public BookingResponse createBooking(#WebParam(name = "bookingInput", targetNamespace = "http://realdolmen.com/", partName = "tariffId") BookingInput input) {
Tariff tariff = tariffService.getTariffById(input.getTariffId());
Booking booking = new Booking.BookingBuilder().withBaggageAllowance(tariff.getFlight().getBaggageAllowance())
.withDayOfDeparture(input.getDayOfDeparture()).withHourOfDeparture(input.getHourOfDeparture()).withTariff(tariff).withDuration(input.getDuration()).createBooking();
bookingServiceBean.createBooking(booking);
BookingResponse bookingResponse = new BookingResponse();
bookingResponse.setBookingId(booking.getId());
bookingResponse.setBaggageAllowance(booking.getBaggageAllowance());
bookingResponse.setDayOfDeparture(createWeirdDateClass(booking.getDayOfDeparture()));
bookingResponse.setDuration(booking.getDuration());
bookingResponse.setHourOfDeparture(booking.getHourOfDeparture());
return bookingResponse;
}
private XMLGregorianCalendar createWeirdDateClass(String lexicalRepresentation) {
try {
return DatatypeFactory.newInstance().newXMLGregorianCalendar(lexicalRepresentation);
} catch (DatatypeConfigurationException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
return null;
}
}
}
our spring service:
#Service
#Transactional
public class BookingServiceBeanImpl implements BookingServiceBean {
#Autowired
BookingDAO bookingDAO;
#Override public void createBooking(Booking booking) {
bookingDAO.createBooking(booking);
}
}
The spring bean can be used in the spring controllers so I don't think there's a problem there..
