Output Spring Boot is reversed in Postman

My problem: when I do an #Post in Postman I get data back from the prices, but not kitten data.
I enter the following:
{
"name": "Frizzle",
"dateOfBirth": "2019-07-27",
"weight": 7.1,
"breed": "Birman",
"firstVaccination": "yes",
"secondVaccination": "yes",
"breedPrice": 8000,
"firstVaccinationPrice": 80.50,
"secondVaccinationPrice": 80.10
}
And this is what I get back in Postman:
{
"id": 3,
"name": null,
"dateOfBirth": null,
"weight": 0.0,
"breed": null,
"firstVaccination": null,
"secondVaccination": null,
"fileUpload": null,
"price": {
"id": 3,
"broadPrice": 8000.0,
"firstVaccinationPrice": 80.5,
"secondVaccinationPrice": 80.1,
"totalPrice": 8160.6
}
}
I've tried changing the code in several places, but I can't figure out why it outputs the price part and not the kitten data part. I want it to output the kitten data. So basically what I want is for him to reverse it, return data of the kittens and give data of the prices that are null.
My files look like this.

I have a lot to say about your code here, but let's see what's the main problem here. The problem is simple if you look at your KittenBuilder you create a Kitten using this builder but your Kitten constructor is empty.
public Kitten(String name, LocalDate dateOfBirth, double weight, String breed, String firstVaccination, String secondVaccination) {
this.name = name;
this.dateOfBirth = dateOfBirth;
this.weight = weight;
this.breed = breed;
this.firstVaccination = firstVaccination;
this.secondVaccination = secondVaccination;
}
This will populate the Kitten object and you're ready to go.
Some advices about your code
If you wonder why it's saving the null values when you specified the null constraints is that recent version of spring boot don't include the validation starter in the web starter, you have to include it yourself.
In you pom.xml add the following dependecy:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
And you have to include the annotation #Transactional to your services to make your operations atomic, for example in your create kitten method you want to persist the price and the kitten atomically.
#Service
#Transactional
class KittenServiceImpl implementes ...
And one the best practices also, is to not use your entites directly in your controllers, use DTO (Data Transfer Object), so you map the properties you want from your entity to your DTO (this way you can include only your kitten properties and leave the price entity).
And last bonus:
public Kitten getKittenById(long id) {
if (!kittenRepository.existsById(id)) {
throw new RecordNotFoundException("");
}
return kittenRepository.findById(id).orElse(null);
}
This can be simplified to:
public Kitten getKittenById(long id) {
return kittenRepository.findById(id).orElseThrow(() -> new RecordNotFoundException());
}

how do I solve the ConstraintViolationException in Spring Boot

I wrote a custom validation in spring boot. The custom validation is meant to check if two fields match. Everything works fine until i try to submit the form. Boom i experience the error:
javax.validation.ConstraintViolationException: Validation failed for classes [com.joker.SampleAuthenticationWebApp.model.User] during persist time for groups [javax.validation.groups.Default, ]
List of constraint violations:[
ConstraintViolationImpl{interpolatedMessage='Passwords do not match!', propertyPath=con_password, rootBeanClass=class com.joker.SampleAuthenticationWebApp.model.User, messageTemplate='Passwords do not match!'}
]
This problem has really hindered my learning progress. Your help would be very much appreciated.
PS: I've Scraped SO in search of a solution but all was to no avail.The Annotation:
package com.joker.SampleAuthenticationWebApp.validator;
import javax.validation.Constraint;
import javax.validation.Payload;
import java.lang.annotation.*;
#Target({ElementType.TYPE, ElementType.ANNOTATION_TYPE})
#Retention(RetentionPolicy.RUNTIME)
#Documented
#Constraint(validatedBy = FieldsValueMatchValidator.class)
public #interface FieldsValueMatch {
String message() default "Fields values don't match!";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
String field();
String fieldMatch();
#Target({ ElementType.TYPE })
#Retention(RetentionPolicy.RUNTIME)
#interface List {
FieldsValueMatch[] value();
}
}
The Validator:
package com.joker.SampleAuthenticationWebApp.validator;
import com.joker.SampleAuthenticationWebApp.model.User;
import org.springframework.beans.BeanWrapperImpl;
import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
public class FieldsValueMatchValidator implements ConstraintValidator<FieldsValueMatch, Object> {
private String field;
private String fieldMatch;
#Override
public void initialize(FieldsValueMatch constraintAnnotation) {
this.field = constraintAnnotation.field();
this.fieldMatch = constraintAnnotation.fieldMatch();
}
#Override
public boolean isValid(Object value, ConstraintValidatorContext context) {
try {
final Object fieldValue = new BeanWrapperImpl(value).getPropertyValue(field);
final Object fieldMatchValue = new BeanWrapperImpl(value).getPropertyValue(fieldMatch);
boolean isValid = fieldValue == null && fieldMatchValue == null || fieldValue != null && fieldValue.equals(fieldMatchValue);
if (!isValid) {
context.disableDefaultConstraintViolation();
context.buildConstraintViolationWithTemplate(context.getDefaultConstraintMessageTemplate()).addPropertyNode(fieldMatch).addConstraintViolation();
return false;
}
return isValid;
}
catch (final Exception ignore) {
// ignore
}
return true;
}
}
The User Model:
package com.joker.SampleAuthenticationWebApp.model;
import com.joker.SampleAuthenticationWebApp.validator.FieldsValueMatch;
import org.hibernate.validator.constraints.Length;
import javax.persistence.*;
import javax.validation.constraints.Email;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import java.util.Set;
#Entity
#Table(name = "auth_user")
#FieldsValueMatch(field = "password", fieldMatch = "con_password", message = "Passwords do not match!")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY, generator = "native")
#Column(name = "auth_user_id", unique = true)
private int id;
#NotNull
#NotEmpty(message = "First name is compulsory")
#Column(name = "firstname")
private String firstname;
#NotNull
#NotEmpty(message = "Last name is compulsory")

#Column(name = "password")
private String password;
#NotEmpty(message = "Confirm Password field is compulsory")
#Transient
private String con_password;
#NotNull
#Column(name = "enabled")
private int enabled;
#ManyToMany(cascade = CascadeType.ALL)
#JoinTable(name = "auth_user_role", joinColumns = #JoinColumn(name = "auth_user_id"), inverseJoinColumns = #JoinColumn(name = "auth_role_id"))
private Set<Role> roles;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getCon_password() {
return con_password;
}
public void setCon_password(String con_password) {
this.con_password = con_password;
}
public int getEnabled() {
return enabled;
}
public void setEnabled(int enabled) {
this.enabled = enabled;
}
public Set<Role> getRoles() {
return roles;
}
public void setRoles(Set<Role> roles) {
this.roles = roles;
}
}

I experienced this problem too . The only way to solve this is to include the annotations of #ModelAttribute and #Valid on your controller class for the bean you want to check weather the condition of #FieldsValueMatch(field = "password", fieldMatch = "con_password", message = "Passwords do not match!") is true , after that include the BindingResult right after the bean you want to check . Check if BindigResult hasErrors(), and return what is your next step .
EX:
#PostMapping("/signup")
public String signup(#ModelAttribute(name = "user") #Valid User user,BindingResult result,Model model)
if (result.hasErrors())
return "signup_form";
Hope this is clear .

spring boot rest for one to many relation

How should I design this addOrders method?

If you are using Spring Data then you will need to create a CrudRepository for each table you which to access. The CrudRepository allows you to easily manipulate data in your table using standard ORM practices. Here is a link with more details.
For more detailed info on how to use Spring Data check out this wonderful guide. This guide has become indispensable when working with Spring Data.

There are many options to this but i have used below approach so hope it helps you. The #Query annotation allows to execute native queries by setting the nativeQuery flag to true.
#Query(value = "select o.* from customer c inner join order o on c.customer_id = o.customer_id where o. = ?1", nativeQuery = true)
Please write sql according to your requirement.

Jakson can not deserialize instance of java.util.ArrayList out of START_OBJECT token

After having sent a POST I receive a 400 error
curl localhost:8888/bills/addbill -H "Content-Type: application/json" -X POST -d '{"number":"111A111", "customer":"Customer Cuustomer Rrrr", "phone":"1 800 5551212", "manager":"Manager Manager Manager", "date":"2012-09-17", "curId":{"id":"1"}, "payments":{["id":"1"]}}'
The response is :
{"timestamp":1503684882518,"status":400,"error":"Bad Request","exception":"org.springframework.http.converter.HttpMessageNotReadableException","message":"Bad Request","path":"/bills/addbill"}
I am getting an exception when I try to deserialize the my json data. How can I deserialize JSON properly?

you have problem in your json
"payments":{["id":"1"]}
since you are trying to deserialize list of type PaymentView this should be, i suppose PaymentView contains id attribute
"payments":[{"id":"1"}]

How to resolve http 500 when I use Jeddic

I had write a restful interface in NetbeansIDE8.2 ,and i have debug it with the PostMan App in chorme, and then an exception have experenced I will show the image down here :
the HTTP ERROR 500
and my code is here ,I have return a arryList to browser
#Path("/getStu")
#GET
public List<TfFreshstudent> queryStudentNoDomitory()
{
List<TfFreshstudent> studentList= cq.queryFreshstudentNoDomitory();
if (studentList.isEmpty()) {
return studentList;
}
return null;
}
and I have tried other sub of the automatic create code ,and the error is also happened:
#GET
public List<TfDormitory> getAllTfDormitories() {
log.debug("REST request to get all TfDormitories");
List<TfDormitory> tfDormitories = tfDormitoryFacade.findAll();
return tfDormitories;
}
I have think that it maybe the return type error maybe ArryList can't be show on browser, maybe I must parse it to json type or response
