When i send a request in json format from Postman, i hava an error : java.lang.IllegalArgumentException: The given id must not be null!
I try to do that in different ways
#RestController
#PostMapping("create")
public AppointmentResponse createAppointment(#RequestBody #Valid AppointmentRequest appointmentRequest) {
return appointmentService.createAppointment(appointmentRequest);
}
public AppointmentResponse createAppointment(AppointmentRequest appointmentRequest) {
Appointment appointmentToSave = appointmentMapper.map(appointmentRequest);
Manicurist manicurist = manicuristRepository.findById(appointmentRequest.getManicuristId()).orElseThrow(
() -> new BusinessException("Manicurist not found")
);
appointmentToSave.setManicurist(manicurist);
Customer customer = customerRepository.findById(appointmentRequest.getCustomerId()).orElseThrow(
() -> new BusinessException("Customer not found")
);
appointmentToSave.setCustomer(customer);
List<NailsService> nailsServices = new ArrayList<>();
for (Integer id : appointmentRequest.getNailsServicesIds()) {
NailsService nailsService = nailsServiceRepository.findById(id).orElseThrow(
() -> new BusinessException("NailsService not found")
);
nailsServices.add(nailsService);
appointmentToSave.setNailsServices((List<NailsService>) nailsService);
}
Appointment appointmentForResponse = appointmentRepository.save(appointmentToSave);
return appointmentMapper.map(appointmentForResponse);
}
public class AppointmentRequest {
private Integer id;
#NotNull
#Future(message = "Please check the date")
private LocalDate appointmentDate;
#NotNull
private LocalTime appointmentTime;
private Integer manicuristId;
private Integer customerId;
private Integer[] nailsServicesIds;
class AppointmentResponnse same with Request

I have an Entity class with a column attribute whose type is an abstract class. I want to serialize (object to JSON string) while saving it in the database column and deserialize it into an abstract class (which in turn converts the string to the appropriate concrete class) when it is retrieved from the database.
Here's how I accomplished it:
ProductEntity.java
#Entity
#Table(name="PRODUCT")
#Data
public class ProductEntity{
#Id
#Column(name = "ID", insertable = false)
#GeneratedValue(strategy = GenerationType.IDENTITY)
private BigInteger id;
#Column(name = "DESCRIPTION")
private String description;
#Column(name = "NAME")
private String name;
#Column(name = "PRODUCT_TYPE")
private String productType;
#Column(name = "PRODUCT_SPECS")
#JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.EXTERNAL_PROPERTY, property =
"productType") // -------------------> Map to concrete class based on productType value
#Convert(converter = ObjectConverter.class) // ------------> custom converter
private ProductSpecification productSpec;
}
NOTE : "PRODUCT_SPECS" database column is of JSON type.
ProductSpecification.java
#NoArgsConstructor
#JsonTypeInfo(use = JsonTypeInfo.Id.MINIMAL_CLASS,
include = JsonTypeInfo.As.WRAPPER_OBJECT,
#JsonSubTypes({
#JsonSubTypes.Type(value = ComputerSpecification.class, name = "computer"),
#JsonSubTypes.Type(value = SpeakerSpecification.class, name = "speaker")
})
public abstract class ProductSpecification{ }
ComputerSpecification.java
#Getter
#Setter
#NoArgsConstructor
#JsonTypeName("computer")
public class ComputerSpecification extends ProductSpecification {
String memory;
String displaySize;
String processor;
#JsonCreator
public ComputerSpecification (#JsonProperty("memory") String memory,
#JsonProperty("displaysize") String displaySize,
#JsonProperty("processor") String processor){
super();
this.memory = memory;
this.displaySize = displaySize;
this.processor = processor;
}
}
SpeakerSpecification.java
#Getter
#Setter
#NoArgsConstructor
#JsonTypeName("computer")
public class SpeakerSpecification extends ProductSpecification {
String dimension;
String sensitivity;
String bassPrinciple;
String amplifierPower;
#JsonCreator
public SpeakerSpecification (#JsonProperty("sensitivity") String sensitivity,
#JsonProperty("dimension") String dimension,
#JsonProperty("bassPrinciple") String bassPrinciple,
#JsonProperty("amplifierPower") String amplifierPower){
super();
this.sensitivity = sensitivity;
this.dimension = dimension;
this.bassPrinciple = bassPrinciple;
this.amplifierPower = amplifierPower;
}
}
ObjectConverter.java
NOTE: I am using Jackson ObjectMapper for serialization and deserialization.
public class ObjectConverter implements AttributeConverter<Object, String>{
private final static Logger LOGGER = LoggerFactory.getLogger(ObjectConverter.class);
private static final ObjectMapper mapper;
static {
mapper = new ObjectMapper();
mapper.setSerializationInclusion(Include.NON_NULL);
}
#Override
public String convertToDatabaseColumn(Object attributeObject) {
if (attributeObject == null) {
return "";
}
try {
return mapper.writeValueAsString(attributeObject);
} catch (JsonProcessingException e) {
LOGGER.error("Could not convert to database column", e);
return null;
}
}
#Override
public Object convertToEntityAttribute(String dbColumnValue) {
try {
if (StringUtils.isBlank(dbColumnValue)) {
return null;
}
return mapper.readValue(dbColumnValue, ProductSpecification.class); // ----> mapped to
abstract class
} catch (Exception e) {
LOGGER.error("Could not convert to entity attribute", e);
return null;
}
}
}
Request body 1:
{
"name" : "Bose Bass Module 700 - Black- Wireless, Compact Subwoofer",
"description" : "This wireless, compact subwoofer is designed to be paired with the Bose sound
bar 700 to bring music, movies, and TV to life with Deep, dramatic bass. ",
"productSpec" : {
"sensitivity" : "90 dB",
"bassPrinciple" : "reflex",
"amplifierPower" : "700 watts",
"dimension" : "14-5/16inW x 42-13/16inH x 16-5/16inD"
}
}
This request gets saved in the database column "PRODUCT_SPECS" as :
{".SpeakerSpecification ":{"sensitivity" : "90 dB","bassPrinciple" : "reflex", "amplifierPower" :"700
watts", "dimension" : "14-5/16inW x 42-13/16inH x 16-5/16inD" }}
Now this solution works perfectly fine. The "SpeakerSpecification " key neither appears in the response of GET API call nor in the swagger doc. But having to store the type info in the database really bothers me.
Is there a better approach to this problem where I could avoid having the typeinfo (".SpeakerSpecification ") in the column value?
I am trying to figure out mickito test for Named Jdbc Template but unable to do so. I did googling but did not find any accurate result. Below is example Code.
Student.class
#Data
public class Student {
private int id;
private String name;
private String address;
public Student(ResultSet rs) throws SQLException {
id = rs.getInt("id");
name = rs.getString("name");
address = rs.getString("address");
}
}
Student class takes ResultSet argument in constructor and mapped all column to variable .
StudentService.class
public class StudentService {
#Autowired
#Qualifier("namedJdbcTemplate")
NamedParameterJdbcTemplate namedParameterJdbcTemplate;
public Student gerStudent(String id) {
Student student;
String selectStudent = "select id , name ,address from student where id=:id";
MapSqlParameterSource mapSqlParameterSource = new MapSqlParameterSource();
mapSqlParameterSource.addValue(id, "id");
student = namedParameterJdbcTemplate.query(selectStudent, mapSqlParameterSource, resultSet -> {
Student response = new Student(resultSet);
return response;
});
return student;
}
}
Can anyone please help on Mockito Test for below line of code?
student = namedParameterJdbcTemplate.query(selectStudent, mapSqlParameterSource, resultSet -> {
Student response = new Student(resultSet);
return response;
});
I have this Meeting and Favorite models;
public class Meeting implements Serializable {
private long id;
private String meetingTitle;
private Date meetingStartDate;
private User host;
}
public class MeetingFavorite implements Serializable {
private long id;
private boolean active = false;
private Meeting meeting;
private Date updatedDate;
}
And I can successfully fetch MeetingFavorite page object like;
#GetMapping(value = "/favorite-meetings", consumes = APPLICATION_JSON_VALUE, produces = APPLICATION_JSON_VALUE)
public ResponseEntity searchFavoriteMeetings(
MeetingFavoriteSpecification search, HttpSession session) {
Page<MeetingFavorite> page = meetingsService.findFavoriteMeetings(search);
return ResponseEntity.ok(page);
}
Is it possible to get Meeting contents only from MeetingFavorite Page w/ it's pagination data?
I tried this and it returns Meeting objects. But pagination data is lost.
Page<MeetingFavorite> page = meetingsService.findFavoriteMeetings(search);
List<Meeting> meetings = new ArrayList<Meeting>();
page.forEach(entity -> meetings.add(entity.getMeeting()));
final Page<Meeting> meetingPage = new PageImpl<>(meetings);
return ResponseEntity.ok(meetingPage);
Oh, I found the way. Thanks.
List<Meeting> meetings = new ArrayList<Meeting>();
page.forEach(entity -> meetings.add(entity.getMeeting()));
Sort sort = new Sort(Sort.Direction.DESC, "updatedDate");
Pageable pageable = new PageRequest(search.getOffset() / search.getLimit(), search.getLimit(), sort);
final Page<Meeting> meetingPage = new PageImpl<Meeting>(meetings, pageable, page.getTotalElements());
return ResponseEntity.ok(meetingPage);
This is what I am trying to achieve:
I have an update request object and user is allowed to do Partial Updates. But I want to validate the field only if it is in the request body. Otherwise, it is OK to be null. To achieve this, I am using GroupSequenceProvider to let the Validator know what groups to validate. What am I doing wrong here? If there is a blunder, how do I fix it?
Documentation: https://docs.jboss.org/hibernate/validator/5.1/reference/en-US/html/chapter-groups.html#example-implementing-using-default-group-sequence-provider
#GroupSequenceProvider(UpdateUserRegistrationGroupSequenceProvider.class)
public class UpdateUserRegistrationRequestV1 {
#NotBlank(groups = {EmailExistsInRequest.class})
#Email(groups = {EmailExistsInRequest.class})
#SafeHtml(whitelistType = SafeHtml.WhiteListType.NONE, groups = {EmailExistsInRequest.class})
private String email;
#NotNull(groups = {PasswordExistsInRequest.class})
#Size(min = 8, max = 255, groups = {PasswordExistsInRequest.class})
private String password;
#NotNull(groups = {FirstNameExistsInRequest.class})
#Size(max = 255, groups = {FirstNameExistsInRequest.class})
#SafeHtml(whitelistType = SafeHtml.WhiteListType.NONE, groups = {FirstNameExistsInRequest.class})
private String firstName;
// THERE ARE GETTERS AND SETTERS BELOW
}
Group Sequence Provider Code:
public class UpdateUserRegistrationGroupSequenceProvider implements DefaultGroupSequenceProvider<UpdateUserRegistrationRequestV1> {
public interface EmailExistsInRequest {}
public interface PasswordExistsInRequest {}
public interface FirstNameExistsInRequest {}
#Override
public List<Class<?>> getValidationGroups(UpdateUserRegistrationRequestV1 updateUserRegistrationRequestV1) {
List<Class<?>> defaultGroupSequence = new ArrayList<Class<?>>();
defaultGroupSequence.add(Default.class);
defaultGroupSequence.add(UpdateUserRegistrationRequestV1.class);
if(StringUtils.hasText(updateUserRegistrationRequestV1.getEmail())) {
defaultGroupSequence.add(EmailExistsInRequest.class);
}
if(StringUtils.hasText(updateUserRegistrationRequestV1.getPassword())) {
defaultGroupSequence.add(PasswordExistsInRequest.class);
}
if(StringUtils.hasText(updateUserRegistrationRequestV1.getFirstName())) {
defaultGroupSequence.add(FirstNameExistsInRequest.class);
}
return defaultGroupSequence;
}
}
I am using Spring MVC, so this is how my controller method looks,
#RequestMapping(value = "/{userId}", method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
#ResponseStatus(HttpStatus.NO_CONTENT)
public void updateUser(#PathVariable("userId") Long userId,
#RequestBody #Valid UpdateUserRegistrationRequestV1 request) {
logger.info("Received update request = " + request + " for userId = " + userId);
registrationService.updateUser(userId, conversionService.convert(request, User.class));
}
Now the problem is, the parameter "updateUserRegistrationRequestV1" in the UpdateUserRegistrationGroupSequenceProvider.getValidationGroups method is null. This is the request object that I am sending in the request body and I am sending email field with it.
What am I doing wrong?
I too went through the same issue ,and hopefully solved it
You just have to check the object is null and put all your conditions inside it.
public List<Class<?>> getValidationGroups(Employee object) {
List<Class<?>> sequence = new ArrayList<>();
//first check if the object is null
if(object != null ){
if (!object.isDraft()) {
sequence.add(Second.class);
}
}
// Apply all validation rules from default group
sequence.add(Employee.class);
return sequence;
}
I'm trying to get a list of objects to render on a Spring 3 MVC app and would like to do this via Ajax.
So in my Spring class I have:
#RequestMapping(value = "/viewSearchEnquiriesAjax", method = RequestMethod.GET, headers = "Accept=application/json")
public #ResponseBody List<Enquiry> getEnquiriesBySearchAjax(#RequestParam String name) {
Search search = new Search();
search.setFirstName(name);
return searchEnquiries(search);
}
But I get a 500 (Internal Server Error) when this is run. This manifests itself when I'm debugging in the browser as 'GET http://localhost:8080/SpringMVC/viewSearchEnquiriesAjax?name=peter 500 (Internal Server Error)'
I can successfully return a single object with no error. Can the Spring Json mapper(Jackson) convert correctly? Am I missing something fundamental?
My javascript is as follows:
function doAjaxPost() {
// get the form values
var firstName = $('#firstName').val();
$.getJSON("/SpringMVC/viewSearchEnquiriesAjax", { name: firstName }, function(result) {
alert("Success");
});
}
My Enquiry object is an Entity:
#Entity
#Table(name = "enquiries")
public class Enquiry implements java.io.Serializable{
private static final long serialVersionUID = -5093725544297637792L;
protected Long id;
protected Date created = new Date();
...
...
public Enquiry() {
}
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "id", unique = true, nullable = false)
public Long getId() {
return this.id;
}
public void setId(Long id) {
this.id = id;
}
...
...
For Jackson you have to create a strongly typed list class because of type erasure:
public class EnquiryList extends ArrayList<Enquiry> {
}
Then return this list from your controller:
#RequestMapping(value = "/viewSearchEnquiriesAjax", method = RequestMethod.GET, headers = "Accept=application/json")
public #ResponseBody EnquiryList getEnquiriesBySearchAjax(#RequestParam String name) {
EnquiryList list = new EnquiryList();
...
return list;
}
