getting auto generated column Id =null in jpa

getting id = null when I try to insert data in table here is my create table syntax

please let me know if anything wrong done by me please help... Thank you

Identity sequencing uses special IDENTITY columns in the database to allow the database to automatically assign an id to the object when its row is inserted. Identity columns are supported in many databases, such as MySQL, DB2, SQL Server, Sybase and Postgres. Oracle does not support IDENTITY columns but they can be simulated through using sequence objects and triggers.
If you are using Oracle, that might be the reason.
You can change this code
#GeneratedValue(strategy = GenerationType.IDENTITY)
To this
#GeneratedValue(strategy = GenerationType.SEQUENCE)

PhysicianJpaController() might not find a physician with "physicianId",so you might be trying to do this:
builder.setPhysician(null);
while you have also this:
physician int(11) NOT NULL

hey guys thank you so much for your help issue that I found is in my entity as I check I found that condition is reserved keyword in mysql and because of this I got this error

Property nulled in the response from Spring/Hibernate

I have a Javascript application that uses Java as a backend with Hibernate, Spring and MySQL DB . When reading data everything works fine and as expected but when trying to edit it on the client side I can see strange behaviour. Even though my server request looks like this :
{"data":{"Draggable":true,"Resizable":true,"StartDate":"2012-09-13T18:00:00+02:00","EndDate":"2012-09-14T04:00:00+02:00","Cls":"","Name":"Secret task","Id":10,"ResourceId":15}}
server responds with :
{"data":[{"Name":"Secret task","Id":10,"StartDate":"2012-09-13T18:00:00+02:00","EndDate":"2012-09-14T04:00:00+02:00","ResourceId":15,"Resizable":null,"Draggable":null,"Cls":""}]}
in which the boolean properties are nulled. I've tried ignoring the setter for this field but without any luck. I also had to remove nullable=false as with this included I was getting an error :
org.springframework.dao.DataIntegrityViolationException: not-null property references a null or transient value: model.Event.draggable; nested exception is org.hibernate.PropertyValueException: not-null property references a null or transient value: model.Event.draggable
This is my MySQL table definition :
CREATE TABLE IF NOT EXISTS `events` (
`Id` int(11) NOT NULL AUTO_INCREMENT,
`Name` varchar(255) DEFAULT NULL,
`StartDate` varchar(50) DEFAULT NULL,
`EndDate` varchar(50) DEFAULT NULL,

) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=12 ;

}
#JsonProperty("Cls")
public void setCls(String cls) {

}
}
Is there anything I can do to prevent this behaviour ?

You are explicitly telling Jackson to ignore the two properties you mentioned, when deserializing your object from its JSON representation. This:
#JsonIgnore
public void setDraggable(Boolean draggable) {
this.draggable = draggable;
}
#JsonIgnore
public void setResizable(Boolean resizable) {
this.resizable = resizable;
}
Basically means, ignore these properties when deserializing from my JSON data. So, consequently when you save your object those properties are null in the database.

You can simply do this:
public boolean getResizable() {
return resizable != null && resizable;
}

JPA find() does not load Entity #Id

I'm starting to use JPA with the OpenJPA API, and i'm having a problem with the find().
Here are the tables:
CREATE TABLE compania (
ID int(11) NOT NULL,
NOMBRE varchar(45) DEFAULT NULL,
PRIMARY KEY (ID)
)
CREATE TABLE modelo (
ID int(11) NOT NULL,
ID_COMPANIA int(11) DEFAULT NULL,
NOMBRE_MODELO varchar(45) DEFAULT NULL,
PRIMARY KEY (ID),
KEY MODELO_COMPANIA_FK_idx (ID_COMPANIA),
CONSTRAINT MODELO_COMPANIA_FK FOREIGN KEY (ID_COMPANIA) REFERENCES compania (ID)
)
and here are my Entities:
#Entity
public class Compania extends EntityJPA{
private static final long serialVersionUID = 1L;
#Id
private int id;
#Column
private String nombre;
#OneToMany(mappedBy="compania",cascade={CascadeType.ALL})
#JoinColumn(name="ID_COMPANIA", nullable=false)
private List<Modelo> listaModelos;
public Compania() {
}
public int getId() {
return id;
}
public void setId(int idCompania) {
this.id = idCompania;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombreCompania) {
this.nombre = nombreCompania;
}
public List<Modelo> getListaModelos() {
return listaModelos;
}
public void setListaModelos(List<Modelo> listaModelos) {
this.listaModelos = listaModelos;
}
}
#Entity
public class Modelo extends EntityJPA{
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;
#Column(name="NOMBRE_MODELO")
private String nombreModelo;
#ManyToOne
#JoinColumn(name="ID_COMPANIA", referencedColumnName="ID")
private Compania compania;
public Modelo() {
}
public Compania getCompania() {
return compania;
}
public void setCompania(Compania compania) {
this.compania = compania;
}
public int getId() {
return id;
}
public void setId(int idModelo) {
this.id = idModelo;
}
public String getNombre() {
return nombreModelo;
}
public void setNombre(String nombreModelo) {
this.nombreModelo = nombreModelo;
}
}
At the moment I make the
Compania cia = getEntityManager().find(Compania.class, idCompania);
the cia object does not have the value of the #Id attribute, it has the value of nombre but not of id. I mean:
cia.getId() = 0
and it must be 1 or 2 , etc. Not 0.
Thank you very much for your help.
I do not have the code to persist because It was already persisted.
the code for the find is
public static Compania findCompania(int idCompania){
try {
Compania cia = getEntityManager().find(Compania.class, idCompania);
return cia;
} finally {
closeEntityManager();
}
}
And if I activate the log, this is the select it shows:
482 testMySql TRACE [http-bio-8080-exec-5] openjpa.jdbc.SQL - <t 1228180882, conn 1699837157> executing prepstmnt 2127861376 SELECT t0.nombre FROM Compania t0 WHERE t0.id = ? [params=(int) 1]
497 testMySql TRACE [http-bio-8080-exec-5] openjpa.jdbc.SQL - <t 1228180882, conn 1699837157> [15 ms] spent
As you can see, there is no t0.id in the select.
Thanks for your help.

Primary Key (ID) not retrieved (?) from database using OpenJPA
Duplicate.... the net of the post is that you need to use a different enhancement method.

If you don't specifically set the value for the #Id attribute you have to declare it with #GeneratedValueso that it's automatically incremented.

What am I missing ?

You haven't told Hibernate that the ID of UserApp was generated automatically by the database:
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name="user_id")
private int userId;
(and do the same for the other entity)

Since your are using bidirectional, change your client code as below.
Session session = (Session) em.getDelegate();
session.beginTransaction();
UserAppDevice ud = new UserAppDevice();
ud.setDeviceName(device);
UsersApp user = new UsersApp(os, token, userNumber, userPassword);
user.setUserAppDevices(new ArrayList<UserAppDevice>())
user.getUserAppDevices().add(ud);
session.save(user);
session.getTransaction().commit();

As mentioned by JB Nizet, you're missing the autogenerated strategy.
An alternative would be to use UUID as your id column and create the values yourself with
#Id
private UUID id = UUID.randomUUID();
Also, don't forget to set equals/hashCode to use the id field as discussed to death in The JPA hashCode() / equals() dilemma
Incidentally, why are you using Session (hibernate specific) instead of sticking to JPA's API?

Hibernate: Transfer seeming n:n mapping in Database to #OneToMany in Hibernate with additional condition

I have a Database with a Mapping between applications and application_descriptions. Every application could have more than one description (mapped by column product_id). Column product_id in table applications can have duplicate values, but combinations of column product_id and column wrapping_version are unique. So the descriptions should only map to the application with highest version.
I have worked out a #OneToMany mapping in table application to get all descriptions. In descriptions I only get the String of product_id. That’s not optimal, but it doesn’t work to map it like in alternative a).
So the solution I have made worked fine for reading data from database, but when I try to update an application to database I get (only sometimes) following error:
Hibernate:
/* update
com.twistbox.iwp.dao.Application */ update
applications
set
created=?,
design_id=?,
message=?,
product_id=?,
product_title=?,
retailer_id=?,
state=?,
tbyb_playduration=?,
tbyb_startups=?,
wrapping_security_layer=?,
wrapping_version=?
where
id=?
Hibernate:
/* delete one-to-many com.twistbox.iwp.dao.Application.applicationDescriptions */ update
application_descriptions
set
product_id=null
where
product_id=?
104330 [http-8080-1] WARN org.hibernate.util.JDBCExceptionReporter - SQL Error: 1048, SQLState: 23000
104330 [http-8080-1] ERROR org.hibernate.util.JDBCExceptionReporter - Column 'product_id' cannot be null
I have tried
1. to set the mapped description set to null before updating
2. set to a new empty HashSet Object before updating
3. let the mapped object like I get it from database
On default hibernate shouldn’t cascade on update and I haven’t found a way to stop doing it (last try was #OneToMany(cascade = {})). I have also tried in both tables true and false values for:
1. attribute null-able
2. updateable
3. insertable
Some of them worked for the application I got the error, but then I get same error for other applications witch only works if I remove the attributes again. Any ideas what to do?
