I am a beginner when it comes to API's and JSON serialization. I'm encountering a weird output. It seems that my JSON output is being wrongly formatted? I am using spring boot 1.59 and when I check my result in postman I am getting the following error:

It happened due to infinite recursion between two entities and I solved using JsonManagedReference, JsonBackReference

I have a two tables: User and Wallet
User have: id
Wallet have: userId, walletName
Now, I want to avoid that so user cant have two wallets with same name.
I create something but it applies to all users, so if user with id 1 create a wallet with name walletSaving no-one can create wallet with that name, while I want to avoid that, I want to create something to check whether the user with id 1 have already wallet with that name.
So far I have this:
if (walletRepository.existsByWalletName(walletRequest.getWalletName())) {
return ResponseEntity.badRequest().body(new MessageResponse("You already have wallet with that name, choose another!"));
}
After some help I tried with something like this:
#PostMapping("/user/{user_id}/wallets")
public ResponseEntity<?> createWallet(#PathVariable(value = "user_id") Long user_id,
#RequestBody Wallet walletRequest, User user) {
if (walletRepository.existsByUserIdAndWalletName(user.getId(), walletRequest.getWalletName())) {
return ResponseEntity.badRequest()
.body(new MessageResponse("You already have wallet with that name, choose another!"));
}
Its still creating wallets with same name.
Just to provide more info.

Wallet Repository
boolean existsByUserIdAndWalletName(Long userId, String walletName);
You need to include the userId in your query:
final long userId = getUserId(); // get the currently authenticated user's id
if (walletRepository.existsByUserIdAndWalletName(userId, walletRequest.getWalletName())) {
return ResponseEntity.badRequest()
.body(new MessageResponse("You already have wallet with that name, choose another!"));
}
existsByUserIdAndWalletName(userId, walletName);
or
findByUserIdAndWalletName(userId, walletName);
If id of the user and walletName is provided, it will check only for that user if it has that wallet name or not, and if in that situation returns something (true or result>0), that will mean that for that specific user the wallet name is already taken.

I would like to do an email search to test, then another login to compare email and password
For your manager class, you have defined all the fields starting with Capital letter ( which is wrong by convention) , therefore you need to update them with small letters only then we will be able to use jpa interface data derived queries ( findByFieldName)
So update the Email field in Manager class to this :
private String email ;
// standard getters and setters
In addition to this,
#GetMapping("/findByEmail/{email}")
public Manager findByEmail(#PathVariable String email){
return managerRepository.findByEmail(email);
};
you need to update this to get mapping. When retrieving objects from database, we use #GetMapping and not Post . also ,we pass variables in the url and not in the request body.
Add #Repositroy annotation to ManagerRepository
and change your class, like
public class Manager {
#Id
#GeneratedValue
private int idManager;
#Column(name = "name", length = 30, nullable = false)
private String name;
#Column(name = "birth", length = 15, nullable = false)
private String birth;
#Column(name = "email", length = 30, unique = true, nullable = false)
private String email;
#Column(name = "CPF", length = 30, unique = true, nullable = false)
private String cpf;
#Column(name = "password", length = 30, nullable = false)
private String password;
#Column(name = "phone", length = 30, nullable = false)
private String phone;
#Column(name = "address", length = 30, nullable = false)
private String address;
#Column(name = "city", length = 30, nullable = false)
private String city;
#Column(name = "state", length = 30, nullable = false)
private String state;
#Column(name = "zipcode", length = 30, nullable = false)
private String zipCode;
#Column(name = "country", length = 30, nullable = false)
private String country;
public ManagerDao(int idManager, String name, String birth, String email, String cpf, String password, String phone, String address, String city, String state, String zipCode, String country) {
this.idManager = idManager;
this.name = name;
this.birth = birth;
this.email = email;

this.phone = phone;

this.city = city;

public void setIdManager(int idManager) {

public void setZipCode(String zipCode) {

public String getCountry() {

Then delete ";" your methods in controller after "}" is not need.

I see this in my spring boot app it inserts all the data for User generating an Id for the new User.
It also inserts all the data for vehicles generating new Ids for Vehicles but in the FK column in Vehicles it inserts null always:
2020-07-12 15:55:20.169 TRACE 14700 --- [nio-8080-exec-2] o.h.type.descriptor.sql.BasicBinder : binding parameter [6] as [BIGINT] - [null]
RestController method for inserting a User:
#PostMapping
#ResponseStatus(HttpStatus.CREATED)
public User insert(#RequestBody User user) {
return userService.save(user);
}
#KavithakaranKanapathippillai the solution that you proposed is working!
"add this user.getVehicles().forEach(vehicle -> vehicle.setUser(user)); before return userService.save(user);"
But I cannot Understand since it is a Json with vehcles inside the User Object why it is not working directly?
Try to remove #Json from methods getUser and setUser and from field User user, and add to your json the user id:
"user": {"id" = 1}
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "idUser")
public UserEntity getUserEntity() {
return teacher;
}
public void setUserEntity(UserEntity idTeacher) {
this.teacher = idTeacher;
}
The following code is in my data model. I use inheritance and I query this data the following way:
Query query1 = session.createQuery("FROM GroupEntity");
List<GroupEntity> groups = (List<GroupEntity>) query1.list();
The problem is. It will join now all the use information. But I only want to select a couple of things. For example. Only the username. And not the password.
Below the UserEnity:
#Entity
#Table(name = "User", schema = "", catalog = "")
#Inheritance(strategy = InheritanceType.JOINED)
public class UserEntity implements Serializable{
private int idUser;
private GroupEntity groupEntity;
private String email;
private String firstName;
private String lastName;
//ToDo Make this password secure!
private String password;
private boolean admin;
private boolean teacher;
public UserEntity(String email, String firstName, String lastName, String password, boolean admin, boolean teacher) {
this.email = email;
this.firstName = firstName;
this.lastName = lastName;
this.password = password;
this.admin = admin;
this.teacher = teacher;
}
public UserEntity() {
}
#Id #GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "idUser")
public int getIdUser() {
return idUser;
}
public void setIdUser(int idUser) {
this.idUser = idUser;
}
#Basic
#Column(name = "email")
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#Basic
#Column(name = "firstName")
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
#Basic
#Column(name = "lastName")
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
#Basic
#Column(name = "password")
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
#Basic
#Column(name = "admin")
public boolean getAdmin() {
return admin;
}
public void setAdmin(boolean admin) {
this.admin = admin;
}
#Basic
#Column(name = "teacher")
public boolean getTeacher() {
return teacher;
}
public void setTeacher(boolean teacher) {
this.teacher = teacher;
}
}
i have this error nested exception is org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): app.Spring.domain.UserDetails.
I now have this user table and in profile i want to edit this UserDetails.
i was trying with GeneratedValue but this doing random id that not associate with user_id also checked generator but this method also dont work.There is so many options so i am lost now.Can someone show some method to mapp this two entities?
User

User_Details

}
public void setId(long id) {
this.id = id;
}
public String getAdres1() {

}
public void setAdres1(String adres1) {
this.adres1 = adres1;
}
public String getAdres2() {
return adres2;
}
public void setAdres2(String adres2) {
this.adres2 = adres2;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;

}
public void setId(Long id) {
this.id = id;

}
}
LOGIC
#RequestMapping(value = "/userDetails", method = RequestMethod.GET)
public String showForm(Model model,
#RequestParam(value = "id", defaultValue = "-1") Long id,
HttpSession session) {
app.Spring.domain.UserDetails va = (id > 0) ? reg.getAdress(id)
: new UserDetails();
model.addAttribute("detal", va);
return "userDetails";
}
#RequestMapping(value = "/userDetails", method = RequestMethod.POST)
public String submit(Model model, #ModelAttribute("detal") UserDetails va,
BindingResult result) {
validator.validate(va, result);
if (result.hasErrors()) {
return "userDetails";
}
reg.saveOrUpdateUserDetails(va);
return "profile";
}
I don't know how to do this with annotations but you might try to manually assign the (hopefully then already present) id fetched from user in the UserDetails entity in the #PrePresist annotated method.
