Hibernate SerializationException: could not deserialize

This is my Data Base
Data Base table photo
When i establish conetion with my Class i specify all column and primary key but when i start my code i get Serialization Exception, in code i am supose to set LocalDate manualy with HTML form but i get serialization exc and Whitelabel Error Page apeare. Please help
My class
package com.developer.SpringMySQL.models;
import org.hibernate.annotations.Type;
import javax.persistence.*;
import java.io.Serializable;
import java.time.LocalDate;
#Entity
#Table(name = "parkingtable")
public class Car implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="carID")
private Integer carID;
#Column(name = "culoarea")
private String culoarea;
#Column(name="model")
private String model;
#Column(name = "combustibil")
private String combustibil;
#Column(name = "categoria")
private String categoria;
#Column(name = "data_inregistrarii")
private LocalDate data_inregistrarii;
public Car() {
}
public Car(String culoarea,
String model, String combustibil, String categoria,
LocalDate data_inregistrarii) {
this.culoarea = culoarea;
this.model = model;
this.combustibil = combustibil;
this.categoria = categoria;
this.data_inregistrarii =data_inregistrarii;
}
public void setCombustibil(String combustibil) {
this.combustibil = combustibil;
}
public LocalDate getData_inregistrarii() {
return data_inregistrarii;
}
public void setData_inregistrarii(LocalDate data_inregistrarii) {
this.data_inregistrarii = data_inregistrarii;
}
public Integer getCarID() {
return carID;
}
public void setCarID(Integer carID) {
this.carID = carID;
}
public String getCuloarea() {
return culoarea;
}
public void setCuloarea(String culoarea) {
this.culoarea = culoarea;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
public String getCombustibil() {
return combustibil;
}
public void setCombustibilul(String combustibil) {
this.combustibil = combustibil;
}
public String getCategoria() {
return categoria;
}
public void setCategoria(String categoria) {
this.categoria = categoria;
}
}
And also i create a controler class

Looks like your LocalDate is not deserialized, so yo need to give it a format,for supporting this POST /carSave?data_inregistrarii=2017-08-04
#RequestMapping(value = "/carSave", method = RequestMethod.POST)
public ModelAndView doHomeSave(#RequestParam("carID") String carID,
#RequestParam("culoarea") String culoarea,
#RequestParam("model") String model,
#RequestParam("combustibil") String combustibil,
#RequestParam("categoria") String categoria,
#RequestParam("data_inregistrarii")
// Add this format
#DateTimeFormat(iso = ISO.DATE) LocalDate data_inregistrarii) {
// code here
}

I think the problem happened in the field mapping, but i do not know how to solve it.

What you are experiencing is the subtle differences that the spring-boot implementation does with both PhysicalNamingStrategy and ImplicitNamingStrategy that ultimately differs from the default that Hibernate does.
As a little history, spring-boot attempts to mimic older Hibernate behavior with their implementations of these strategies to ease the upgrade process for legacy applications.
Their strategy essentially translates securityLevel to security_level at the database level rather than it being an explicit pass-thru like the default hibernate implementations.
You can try overriding their strategy definitions in your spring configuration to use the default ones that ship with Hibernate instead to see if that resolves yours conflicts.
The two spring-boot settings of interest are:
spring.jpa.hibernate.naming.physical-strategy
spring.jpa.hibernate.naming.implicit-strategy
The hibernate defaults are:
org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
org.hibernate.boot.model.naming.ImplicitNamingStrategyJpaCompliantImpl

Detached entity passed to persist Spring in one to many relationship

So I have a problem, I have users who live in an apartment, and in one apartment there can live more than one user. So that makes it one too many relationships. And these are my entity classes:
AppUser class:
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
#Column(unique = true)
private String username;
private String password;
#ElementCollection(fetch = FetchType.EAGER)
private List<String> roles = new ArrayList<>();
#ManyToOne
#JoinColumn(name = "apartmen_id")
#JsonIgnoreProperties(value = {"apartmen_tenats"}, allowSetters=true)
private Apartmen apartmen; // apartmen in which he lives
this is my apartmen class:
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
private String location;
private int numberOfTenats;
private boolean hasBuilding;
#ManyToOne
#JoinColumn(name = "building_id")
#JsonIgnoreProperties(value = {"apartments"}, allowSetters=true)
private Building apartmenBuilding;
#OneToMany(mappedBy = "apartmen", cascade=CascadeType.ALL)
#JsonIgnoreProperties(value = {"apartmen"}, allowSetters = true)
private Set<AppUser> apartmen_tenats;
when I create new apartment, the object sent from the client has id null, but every else is set normal like I entered it in the form. I don't know if that is important or not. Here is the code for my controller:
/**
* Method for adding a apartmen
*
* #param Apartment
* #return
*/
#PreAuthorize("hasRole('ROLE_ADMIN')")
#RequestMapping(value = "/apartmens", method = RequestMethod.POST)
public ResponseEntity<Apartmen> createApartmen(#RequestBody Apartmen apartmen) {
System.out.println(apartmen.toString());
Apartmen foundApartmen = apartmenService.findOneByName(apartmen.getName());
if (foundApartmen != null) {
throw new RuntimeException("Name already exist");
}
apartmen.setNumberOfTenats(apartmen.getApartmen_tenats().size());
Apartmen newApartmen = apartmenService.save(apartmen);
for (AppUser tenat : apartmen.getApartmen_tenats()) {
tenat.setHasBuilding(true);
tenat.setApartmen(newApartmen);
appUserRepository.save(tenat);
}
return new ResponseEntity<Apartmen>(newApartmen, HttpStatus.CREATED);
}
And I get this error message back to my client as a response:
detached entity passed to persist: com.projekat.kts.model.AppUser; nested exception is org.hibernate.PersistentObjectException: detached entity passed to persist: com.projekat.kts.model.AppUser
And the full error is:

That entity should be merged not persisted. In theory spring data jpa should take care of that but I always had problems with it.
In your service you can inject the persistence context yourself and perform the required operation:
#PersistenceContext
private EntityManager entityManager;
..
public Appartmen merge(Appartmen a){
return entityManager.merge(a);
}
then in controller:
Apartmen newApartmen = apartmenService.merge(apartmen);
as there is casading on the Appuser it should get merged also

Trouble mapping SQL Query to Entity spring-data-jpa

I'm new to Spring and trying to workout how to map a SQL Query to a model object. The prototype I'm developing serves a rest api over the top of a data warehouse. Mapping a database table to an object is easy enough but some objects will be represented by more complex queries. So far I have tried #NamedNativeQuery with #SqlResultsMapping and #Entity annotations but have run into some problems. I suspect I'm not using them properly?
I can get the server up and running but I get an error when trying to access via localhost:8080/admissionEvents. I'm using a sqlite db but have the same issue using the production mssql db. From what I can tell from there's a SQLException that is looking for a table? That would suggest something is wrong in my mapping? Are the annotations in the right place?
I don't have a persistence.xml file defined but my db connection details are set in application.properties. Not sure though if thats the source of the problem?
Any help much appreciated.

Try following way.

Managed to find a solution by adding the #Subselect and #Synchonize annotations to the Entity Class.
#Entity(name="AdmissionEvent")
#Subselect("SELECT fact_admission_event.fact_admission_event_key,fact_admission_event.ward FROM fact_admission_event")

Here is my code :
Book.java
#Entity
#Table(name = "book")
public class Book {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
#Column(name = "book_title", nullable = false)
private String bookTitle;
#Column(name = "book_description", nullable = true)
private String bookDescription;
#Column(name = "book_unit_price", nullable = false)
private Float bookUnitPrice;
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "author_id")
private Author author;
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "publisher_id")
private Publisher publisher;
}
BookDAO.java
#Repository("bookDao")
public interface BookDAO extends JpaRepository<Book, Long> {
public List<Book> findByBookTitle(String name);
public List<Book> findByBookUnitPrice(Float price);
public List<Book> findByBookUnitPriceBetween(Float start , Float end);
}
BookServiceImpl.java has the following implementation of save method
#Override
public Book save(Book book) {
if(!bookDao.exists(book.getId()))
return bookDao.save(book);
else {
Book existingBook = bookDao.findOne(book.getId());
existingBook.setBookTitle(book.getBookTitle());
existingBook.setBookDescription(book.getBookDescription());
existingBook.setAuthor(book.getAuthor());
existingBook.setPublisher(book.getPublisher());
return bookDao.save(existingBook);
}
}
BookController.java has the following implementation of save rest endpoint.
#RequestMapping(value = "/save", method = RequestMethod.POST, consumes = "application/json",
produces = "application/json")
public ResponseEntity<Book> save(#RequestBody Book book) {
return new ResponseEntity<Book>(bookService.save(book), HttpStatus.OK);
}
And finnaly the payload I am passing to the save method.
{
"bookTitle": "Java Complete Reference",
"bookDescription": "A great book to start java for beginners",
"bookUnitPrice": 100,
"author": {
"id": 1,
"firstName": "First Name",
"lastName": "Last Name",
"bio": "Author Bio"
},
"publisher": {
"id": 4,
"publisherName": "Continental Publications"
}
}
When I pass this payload via HTTP post method to the rest endpoint I get the exception mentioned above.
Now I want to persist a Book entity which refers to the existing Author and Publisher entity.
I have searched for some problem of similar kind but none of the solutions are of my help.Can someone please suggest what am I doing wrong and what needs to be changed?
Thanks for the help in advance.

I was going through this question on stackoverflow and tried one of its solution and it worked for me.
Replacing
#OneToOne(cascade = CascadeType.ALL)
with
#OneToOne(cascade = CascadeType.MERGE)
worked for me.
Now I don't know if it is a Hot-fix or why I didn't work with CascadeType.ALL

This is a general architecural problem which I see rarely addressed.
The point is that your JPA entities can be in several states:
transient only
persistent unchanged attached
persistent unchanged detached
persistent changed detached
persistent changed attached unflushed
persistent changed attached flushed
Often I see JPA entities passed around and even serialized so they exit the JPA context an become "detached".
You should have a clear answer to ANY state of your JPA Entity in the architectural context. If you do not adress it it becomes micro management and your code will be more and more inexpressive as you always have to be aware which method is save to call in which state of the JPA entity.
To your question:
A simple possibility would be to load the entity by id to get an attached representation and map the values from the detached entity to the attached entity.
The real problem is that your entity quietly became a communication object ( I call it suggestion or proposal object). It is an object that works together in the context of the operation to perform (create/update/delete/read). That said it is only tip of the architectural iceberg.
