I am trying to execute a couple of queries on different threads. There are 2 top level queries each executing on different tables at runtime. For executing the first set of queries (executeQuery1()), I spawn 2 different threads and they are processed well. From the output of these queries, I have to extract a list of ids and then fire another set of queries (executeQuery2()) on entirely different threads. As soon as the second set of queries are about to be submitted to the database, I see that EntityManager is closed and the application shutdown.

I believe that this has something to do with the EntityManagers being used in multi-threaded env. However, when I read the documentation, #Transactional will supply a new EM everytime. If the executeQuery1() was able to run 2 queries in parallel on different threads, why is executeQuery2() closing the EM?

However, in my result, I am getting the value back as null. Also, I know that I should be getting an error that the table PERSON already exists and it that it should not be declared in the schema, but that is not the case.
After checking the h2 database, I see that none of the values are inserted.
You can try adding spring.jpa.hibernate.ddl-auto=create to your property file. You can check this question here in stackoverflow or from the documentation.
I have transactional service that I use to create a Person and persist it in db.
The problem is that entity is not saved into db after transaction is commited.
At first I thought it was the fault of the JpaRepository, which opens a new transaction every time a method is called, but from what I've learned, these are just logical transactions inside a single physical one that gets opened in my service.
I use Spring Boot and Hibernate to connect with my firebird databases.
For this purpose i configured two separate datasources and transaction managers.
In each #Transactional annotation, I specify the transaction manager to be used.
Fetching data works perfect. The problem concerns only saving.
I'm actually performing more operations here, but for the sake of the example I'll limit myself to just saving the entities.
Simple example below.
#Transactional("secondaryTransactionManager")
#RequiredArgsConstructor
public class PersonServiceImpl implements PersonService {
private final PersonJpaRepository personJpaRepository;
#Override
public String savePerson() {
var personEntity = new PersonEntity();
personEntity.setName("Slawek");
personEntity.setSurname("Filip");
personEntity.setPersonalNumber("12341234123");
var save = personJpaRepository.save(personEntity);
return save.getName();
}
}
Person entity is not saved in db though. There are logs

Why it's not working?
What have I missed?
Ok, the problem was that JPA entities does not work with DataSourceTransactionManager.
I used JpaTransactionManager instead and it works fine
I've really been struggling with a multiple (2) db setup in springboot. I've spent countless of hours and followed many examples and I've read the complete documentation.
I find it hard to decide what should be added in my code because there are so many examples with different solutions around. There's Spring, Spring-boot, hibernate, jpa, beans, xml files, annotations, corrupt dependencies.
I've come up with a piece of code that doesn't give errors and saves my data. But, only the data to the primary database gets saved. The insert in the second db is happening according to the sql trace but no commit. What's going on here?
I also made a simple controller class to insert data with an http request, but it had the same results: only user in db1 gets saved, product in db2 doesn't.
If anybody has any clue it would be greatly appreciated. It's driving me nuts!
I realize this is just a simple piece of code, but it's test to see if I can use this approach in a bigger project.
Thanks!

You have not included Product Repository and User Repository class,please check the annotation in the class
Did you use Entity Manager
if Yes then
Did you use #PersistenceContext annotation for the entity manager
please follow the below example,try to run it on your local by just copy pasting the code and seeing the configuration
Spring Boot + JPA
if you have used CRUD Repository
You can refer to the below code
Spring Boot+CRUD Repository+JPA
Both are running in my local
my entity Client

please help me
The error message is telling you exactly what the problem is
Caused by: org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): meinpro.entiti.Compte
The id in your Compte class is not a generated value, like the other tables
#Id
private String codeCompte;
So you need to set this value yourself before you save it.
Now look at the CompteEpargne and the CompteCourant (which extend Compte) constructors
public CompteEpargne(String s, Date date, int i, Client c2, double taux) {
this.taux = taux;
}
public CompteEpargne(String codeCompte, Date dataCreation, double solde, Client client, Collection<Operation> operations, double taux) {
super(codeCompte, dataCreation, solde, client, operations);
this.taux = taux;
}
public CompteCourant(String s, Date date, int i, Client c1, double decouvert) {
this.decouvert = decouvert;
}
public CompteCourant(String codeCompte, Date dataCreation, double solde, Client client, Collection<Operation> operations, double decouvert) {
super(codeCompte, dataCreation, solde, client, operations);
this.decouvert = decouvert;
}
The first constructor of each type only sets one value, while the second calls the super constructor, which set all the values (id included). When you are saving, you are using the first constructor
Compte cp1=compteRep.save(new CompteCourant("c1",new Date(),9000,c1,6000));
Compte cp2=compteRep.save(new CompteEpargne("c2",new Date(),63000,c2,12220));
You are calling the constructor that only sets one value. So you probably need to fix how that those constructors are setting properties. Maybe you want to do something like
public CompteEpargne(String s, Date date, int i, Client c2, double taux) {
this(s, date, i, c2, new ArrayList<Operation>(), taux);
}
where you call the other constructor.
Simple Solution
Your id attribute is not set. This may be due to the fact that the DB field is not set to auto increment.
For MySQL (as you have given in Properties file) use this below sample for defining your POJO class.
#Id #GeneratedValue(strategy = GenerationType.IDENTITY) #Column(name="id", unique=true, nullable=false) public Long getId() { return this.id; }
thanks friends the problem is in the class Compte
#DiscriminatorColumn(name = "TYPE_CPTE,",discriminatorType= DiscriminatorType.STRING,length = 2)
with in the name is ="TYPE_CPTE," hhhh I dont see the comma after TYPE_CPTE
#DiscriminatorColumn(name = "TYPE_CPTE",discriminatorType= DiscriminatorType.STRING,length = 2)
