Question marks when inserting Hebrew words

I know that we have this question before but this is different.
I'm building a Web Application Spring based

so I debugged the app and I see that the request is OK
so I explored and I see that I need to make my database UTF-8 didn't help at all I still getting ?????
now the strange part when I changed my JDBC driver from
jdbc:mysql://host:3306/DatabaseName
to
jdbc:mysql://host:3306/DatabaseName?useUnicode=yes&characterEncoding=UTF-8
I start to get exception

CREATE TABLE teacher ( id bigint(20) unsigned NOT NULL AUTO_INCREMENT, description varchar(255) CHARACTER SET latin1 DEFAULT NULL, full_name varchar(255) CHARACTER SET latin1 DEFAULT NULL, gear tinyint(1) NOT NULL, image varchar(255) CHARACTER SET latin1 DEFAULT NULL, phone_number bigint(20) NOT NULL, price int(11) NOT NULL, rating float NOT NULL, rating_count int(11) NOT NULL, school varchar(255) CHARACTER SET latin1 DEFAULT NULL, teaching_area varchar(255) CHARACTER SET latin1 DEFAULT NULL, vehicle_type varchar(255) CHARACTER SET latin1 DEFAULT NULL, PRIMARY KEY (id), UNIQUE KEY id (id) ) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8

Probably the problem that you have
description varchar(255) CHARACTER SET latin1
in your table fields. Try to use
description varchar(255) CHARACTER SET utf8
it will resolve the problem.

CREATE TABLE `teacher` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`description` varchar(255) CHARACTER SET latin1 DEFAULT NULL,
`full_name` varchar(255) CHARACTER SET latin1 DEFAULT NULL,
`gear` tinyint(1) NOT NULL,
`image` varchar(255) CHARACTER SET latin1 DEFAULT NULL,
`phone_number` bigint(20) NOT NULL,
`price` int(11) NOT NULL,
`rating` float NOT NULL,
`rating_count` int(11) NOT NULL,
`school` varchar(255) CHARACTER SET latin1 DEFAULT NULL,
`teaching_area` varchar(255) CHARACTER SET latin1 DEFAULT NULL,
`vehicle_type` varchar(255) CHARACTER SET latin1 DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8

JPA: Prevent cascade update in unidirectional onetomany mapping

I've a parent entity named QuestionPaper:
#Entity
#Table(name = "question_paper")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaper {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_id", columnDefinition = "INT")
private int questionPaperId;
#Column(nullable = false, length = 150)
private String name;
#OneToMany
#JoinColumn(name = "question_paper_id")
#OrderBy("order")
private Set<QuestionPaperCategory> questionPaperCategorys = new HashSet<QuestionPaperCategory>();
}
and a child entity QuestionPaperCategory:
#Entity
#Table(name = "question_paper_category")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaperCategory {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_category_id", columnDefinition = "INT")
private int questionPaperCategoryId;
#Column(name = "question_paper_id")
private int questionPaperId;
....
}
I want to update just QuestionPaper without updating the child rows (QuestionPaperCategory). Just change the name field.
So, I tried
QuestionPaper qPaper = new QuestionPaper();
qPaper.setQuestionPaperId(1)
qPaper.setName("Exam-101")
qPaperRepository.save(qPaper);
But it is throwing the following error. I think it's trying to cascade update the child tables. I want to prevent that.

It shows this query in the error.[update question_paper_category set question_paper_id=null where question_paper_id=?]
Why is it trying to update question_paper_category when I've not set in in QuestionPaper

Instead of creating new object, you have two ways of updating entities. First - fetch your entity, update fields and save:
QuestionPaper qPaper = qPaperRepository.findOne(1);
qPaper.setName("Exam-101")
qPaperRepository.save(qPaper);
In this you will update only fields you want, other fields will be unaffected. Notice, that if you are using lazy loading you will not fetch all related entities.
Second is to create update by repository without fetching entity:
#Modyfing
#Query("update QuestionPaper qp set qp.name= ?2 where qp.questionPaperId = ?1")
void updateName(String id, String name);
Of course, if you want to update more fields you can put more parameters into your query.

I believe the root of the problem is you have an auto generated Id, but you are creating a new instance and manually specifying it.
Try leaving your Id null and let the auto generation do it's thing.
Alternatively if you are trying to update an existing record, retrieve the record first then edit it. There will be no need to set the Id for this approach because it will already be in the retrieved object.
Additionally your joining column should be specified in your #OneToMany.

In the QuestionPaper.java, you can config the value of the cascade attribute about the #OneToMany,and delete the annotation of #JoinColumn(name = "question_paper_id") what should be used in the #ManyToOne.
#Entity
#Table(name = "question_paper")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaper {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_id", columnDefinition = "INT")
private int questionPaperId;
#Column(nullable = false, length = 150)
private String name;
#OneToMany(mappedBy="questionPaper", fetch=FetchType.LAZY)
// #JoinColumn(name = "question_paper_id")
// #OrderBy("order")
private Set<QuestionPaperCategory> questionPaperCategorys = new HashSet<QuestionPaperCategory>();
}
QuestionPaperCategory.java
#Entity
#Table(name = "question_paper_category")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaperCategory {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_category_id", columnDefinition = "INT")
private int questionPaperCategoryId;
// #Column(name = "question_paper_id")

java.sql.SQLException: Field 'client_id' doesn't have a default value

I'm trying, using JSON (via Postman) to use POST and GET methods on my database tables (Clients, Cars and Rentals), where clients_id and cars_id are foreign keys in Rentals table.
I'm not sure if I done the foreign keys mapping right, because everything works just fine for Clients and Cars tables.
This is how I tried to do this in my Rental entitites class:
#Entity
#Table(name="rentals")
public class Rentals {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
private Date rental_date;
private String status;
#OneToOne(cascade = CascadeType.ALL, fetch=FetchType.EAGER)
#PrimaryKeyJoinColumn(name="client_id")
private Clients client;
#OneToOne(cascade = CascadeType.ALL, fetch=FetchType.EAGER)
#PrimaryKeyJoinColumn(name="car_id")
private Cars car;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public Clients getClient() {
return client;
}
public void setClient(Clients client) {
this.client = client;
}
public Cars getCar() {
return car;
}
public void setCar(Cars car) {
this.car = car;
}
public Date getRental_date() {
return rental_date;
}
public void setRental_date(Date rental_date) {
this.rental_date = rental_date;
}
}
Also these are my entites class for Clients:
#Entity
#Table(name="clients")
public class Clients {
#Id
#GeneratedValue(strategy= GenerationType.AUTO)
private Integer client_id;
public Integer getClient_id() {
return client_id;
}
public void setClient_id(Integer client_id) {
this.client_id = client_id;
}
private String name,surname,place_of_residence,id_number;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
public String getPlace_of_residence() {
return place_of_residence;
}
public void setPlace_of_residence(String place_of_residence) {
this.place_of_residence = place_of_residence;
}
public String getId_number() {
return id_number;
}
public void setId_number(String id_number) {
this.id_number = id_number;
}
}
and Cars:
#Entity
#Table(name="cars")
public class Cars {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer car_id;
private String brand,model,licence_plate_number,production_year,price_per_day;
public Integer getCar_id() {
return car_id;
}
public void setCar_id(Integer car_id) {
this.car_id = car_id;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
public String getLicence_plate_number() {
return licence_plate_number;
}
public void setLicence_plate_number(String licence_plate_number) {
this.licence_plate_number = licence_plate_number;
}
public String getProduction_year() {
return production_year;
}
public void setProduction_year(String production_year) {
this.production_year = production_year;
}
public String getPrice_per_day() {
return price_per_day;
}
public void setPrice_per_day(String price_per_day) {
this.price_per_day = price_per_day;
}
}
This is the JSON enquiry that i'm using:
{
"client_id":2,
"car_id":4,
"rental_date":"2017-06-05",
"status":"rented"
}
Also, here's my RentalsController Class:
#RestController
#RequestMapping("/rentals")
public class RentalsController {
private final RentalsRepository rentalsRepository;
public RentalsController(RentalsRepository rentalsRepository){
this.rentalsRepository = rentalsRepository;
}
#RequestMapping(method = RequestMethod.POST)
public void addRental(#RequestBody Rentals rental){
rentalsRepository.save(rental);
}
#RequestMapping(method = RequestMethod.GET)
public List<Rentals> getRentals(){
return rentalsRepository.findAll();
}
}

Edit 1: following advices from #Dazak and #Wolf, I changed the columns names that I wanted to join (aka foreign keys in Rentals table) to client_id and car_id.
Also, I tried to change the PrimaryKeyJoinColumn annotation to JoinColumn annotation, but none of these worked. Am I doing something wrong? Thank you in advance for your help!
Edit 2: I also changed names of primary keys in Clients and Cars tables in my database to client_id and car_id (not sure if it is a proper way to handle the problem), but still, it didn't help.

This is not going to work. If you are using an ORM model you can't work with IDs anymore. You request provides a client_id and a car_id:
{
"client_id":2,
"car_id":4,
"rental_date":"2017-06-05",
"status":"rented"
}
However, the Rentals object (!) does neither have a property called car nor client. I guess these additional properties are simply ignored. What the Rental object does have is a reference to car and client objects (!) that hold those IDs.
So you JSON has to look something like this:
{
"client":{"client_id": 2}
"car":{"car_id": 4},
"rental_date":"2017-06-05",
"status":"rented"
}
(I hope my JSON is correct. I am not very familiar with JavaScript.)
BTW: You OneToOne mapping seems wrong. Unless you are renting out each car only once to one customer it should be a ManyToOne.

Why my hibernate relation doesn't work?

See my class with relation :
#Entity
#Table(name = "t_aquarium")
public class UserPoissonDO {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "id")
private Integer id;
#ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH })
private User user;
#ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH })
private PoissonDO poissonDO;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public PoissonDO getPoissonDO() {
return poissonDO;
}
public void setPoissonDO(PoissonDO poissonDO) {
this.poissonDO = poissonDO;
}
}
When I save it in my BDD with JPA, I've the following error :
detached entity passed to persist: com.javaquarium.beans.data.PoissonDO;
nested exception is org.hibernate.PersistentObjectException: detached entity
passed to persist: com.javaquarium.beans.data.PoissonDO
In my database, I like to save the UserPoissonDO object with relation to the User and the specie of the Fish.
UserPoisson is associated with one User and one User can have more than one fish.
I think my relation is bad... if it's the case explain me why. I've follow an example for this.
EDIT :
See my PoissonUserService for persisting UserPoissonDO

I believe the solution provided here: Spring data jpa detached entity, will also work for this situation.
The issue is that UserPoissonDO is a new object, but its PoissonDO is detached. Spring will attempt to persist UserPoissonDO since it is a new object, but doesn't know that it needs to merge() PoissonDO into the existing persistence context and manage it.
As explained in the linked post:
If you can ensure that PoissonDO will be saved separately or already exists, removing CascadeType.PERSIST will work. Otherwise, you will need to perform a merge() using a custom repository and EntityManager.

org.springframework.dao.DataIntegrityViolationException - when saving Objects

I am facing a DataIntegrityViolationException when I want to insert data into my h2 database. There are two entities I am using which are Team and Driver. The Team entity contains a driverList which should store Driver objects in it.
Team Class:
#Entity
public class Team {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
#ElementCollection
#OneToMany(mappedBy = "team", cascade = CascadeType.MERGE)
private List<Driver> driverList = new ArrayList<>();
/** Constructor **/
public Team(Long id, String name, List<Driver> driverList) {
super();
setId(id);
setName(name);
setDriverList(driverList);
}
/** Default - Constructor **/
public Team(){
super();
this.name = null;
this.driverList = null;
}
/** Getters and Setters **/
public List<Driver> getDriverList() {
return driverList;
}
public void setDriverList(List<Driver> driverList) {
this.driverList = Ensurer.notNull(driverList, "driverList");
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = Ensurer.notNull(id, "ID");
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = Ensurer.notNull(name,"Name");
}
Driver Class:
#Entity
public class Driver {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private LocalDateTime birthdate;
private String name;
private String nationality;
#ManyToOne(cascade = CascadeType.MERGE)
private Team team;
public Driver() {
super();
this.id = null;
this.name = null;
this.birthdate = null;
this.nationality = null;
this.team = null;
}
public Driver(Long id, String name, LocalDateTime birthdate, String nationality, Team team) {
super();
this.id = Ensurer.notNull(id,"id");
this.name = Ensurer.notNull(name,"name");
this.birthdate = Ensurer.notNull(birthdate,"birthdate");
this.nationality = Ensurer.notNull(nationality,"nationality");
this.team = Ensurer.notNull(team,"team");
}
/** Getters and Setters **/
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = Ensurer.notNull(id, "id");
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = Ensurer.notNull(name, "name");
}
public LocalDateTime getBirthdate() {
return birthdate;
}
public void setBirthdate(LocalDateTime birthdate) {
this.birthdate = Ensurer.notNull(birthdate, "birthdate");
}
public String getNationality() {
return nationality;
}
public void setNationality(String nationality) {
this.nationality = Ensurer.notNull(nationality, "nationality");
}
public Team getTeam() {
return team;
}
public void setTeam(Team team) {
this.team = Ensurer.notNull(team, "team");
}
DriverRepository Interface:
#Repository
public interface DriverRepository extends CrudRepository<Driver, Long> {
}
Create Driver Method in DriverServiceBean:
#Override
public boolean createDriverFrom(String name, LocalDateTime birthDate,
String nationality, Team team) {
Driver Driver = new Driver();
Driver.setName(name);
Driver.setBirthdate(birthDate);
Driver.setNationality(nationality);
Team t = team;
Driver.setTeam(t);
DriverRepository.save(Driver);
return true;
}
Error Message:
