I have the below entity where the deleted column in database is of type character with expected values 'Y' or 'N' . I'm using the YesNoConverter to encode the boolean value as 'Y' or 'N' .
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
.
.
#Column(name = "deleted")
#Convert(converter= YesNoConverter.class)
private boolean deleted;
}
But this code is giving error when I have a derived query method querying on the boolean property like below
public interface UserRepository extends JpaRepository<User,Long> {
List<User> findByDeletedFalse();
}
This repository method throws below exception

Mysql database table structure:
database table structure
Customer.java class:
#JsonIgnore
#OneToMany(mappedBy = "customer")
private Set<OrderLine> orderLine = new HashSet<>();
Orderline.java class:
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name = "id")
private Long id;
#ManyToOne(cascade=CascadeType.ALL)
#JoinColumns({
#JoinColumn(name = "customer_id", referencedColumnName = "customer_id")})
private Customer customer;
Saving data through OrderLineController class:
#PostMapping("/orderLines")
public ResponseEntity<OrderLine> createOrderLine(#RequestBody OrderLine orderLine) {
OrderLine _orderLine = orderLineRepository.save(orderLine);
return new ResponseEntity<>(_orderLine, HttpStatus.CREATED);
}
Here is my Test file:
OrderLine newOL = new OrderLine(order, product);
newOL.setQty(1);
newOL.setCustomer(customer);
ResponseEntity<OrderLine> respOL = restTemplate.postForEntity("/api/orderLines", newOL, OrderLine.class);
assertEquals(HttpStatus.CREATED, respOL.getStatusCode());
I have previously populated an existing data in the Customer table, and now I tried to create new purchase order based on the existing customer.
In my Test file, when the save() function is executed, Jpa sees the "customer" as a new customer, but it was actually returned from the previous method:
ResponseEntity<Customer> getCustomersByCustomerId(String customerId)
Therefore trying to add a record with the same customer_id produced error, but indeed I was hoping the JpaRepository could figured out the customer_id is the same as the existing customer record, but it doesn't. The Jpa repository tried to insert this record into the customer table, thus resulting Duplicate entry error: I have been searching for possible solution for the past 5 days, but the issue still persist. Your help is much appreciated.

I have a little problem to understand why lazy fetching have different behaviour when I'm trying to execute 'findAll' method from REST controller and CRON job.
I have two simple entities:
#Entity
#Data
public class MainEntity {
#Id
#GeneratedValue(generator = "MainEntitySeqGen", strategy = GenerationType.SEQUENCE)
#SequenceGenerator(name = "MainEntitySeqGen", sequenceName = "main_entity_seq")
private Long id;
#OneToMany(fetch = FetchType.LAZY)
#JoinColumn(name = "main_id", foreignKey = #ForeignKey(name = "FK_mainEntity_nestedEntity"))
private Set<NestedEntity> nestedEntities;
}
and
#Entity
#Data
public class NestedEntity {
#Id
#GeneratedValue(generator = "NestedEntitySeqGen", strategy = GenerationType.SEQUENCE)
#SequenceGenerator(name = "NestedEntitySeqGen", sequenceName = "nested_entity_seq")
private Long id;
#Column
private String sample;
}
and service with method to find all 'MainEntities'. This service doesn't have any #Transactional annotations! (I don't have it in whole project)
#Override
public List<MainEntity> findAll() {
log.info("Finding all main entities...");
return repository.findAll();
}
I have one additional service to test lazy initialization exception with method:
#Override
public void testMe() {
List<MainEntity> entities = mainEntityService.findAll();
if (!entities.isEmpty()) {
log.info("Nested entities size: {}", entities.get(0).getNestedEntities().size());
}
}
Still no transactions on method or service!
Ok, and now, when I'm trying to execute testMe method from REST controller:
#GetMapping
public ResponseEntity<Void> testMe() {
log.info("Execution from API: Not throwing LazyInitializationException");
testService.testMe();
return ResponseEntity.ok().build();
}
I have correct output:

Please note that TransactionInterceptor says, he completed transaction for 'findAll' (from repository) but nevertheless he's invoking SELECT query to fetch NestedEntities that should be loaded lazily and I expected it throw exception (but not).
And this same 'testMe' method executed from CRON:
#Scheduled(cron = "*/10 * * * * *")
public void testCron() {
log.info("Execution from CRON: Throwing LazyInitializationException");
testService.testMe();
}
is throwing exception:

Does anyone have idea why it works like that?
I use:
Spring Boot: v2.6.7
Hibernate: v5.6.8
I founded answer for this "problem" - cause is "Open Session In View" Spring mechanism.
Links:
#RestController methods seem to be Transactional by default, Why?
https://www.baeldung.com/spring-open-session-in-view
The error tell you that you're trying to fetch a lazy association, but there is no existing Hibernate Session for your current thread since you do it outside a transactional context.
Using JPA without delimiting your transaction boundaries explicitly with #Transactional is not a good thing because it creates an obscure code that creates a lot of short-lived Session and bypasses a lot of features that Hibernate offers you (session-level repeatable read, write-behind...)

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)
I've modified the Spring Boot JPA Data example (https://github.com/spring-guides/gs-accessing-data-jpa.git) slightly adding an Order entity and a corresponding one to many mapping to it from the customer. When I run the example there are several Syntax Error in SQL Statement lines logged by Hibernate. I'm trying to figure out why? I've pasted the code for the entities and the console output from the application below.
package hello;
import java.util.List;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
#Entity
public class Customer {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
private String firstName;
private String lastName;
#OneToMany(mappedBy="customer")
private List<Order> orders;
protected Customer() {}
public Customer(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
#Override
public String toString() {
return String.format(
"Customer[id=%d, firstName='%s', lastName='%s']",
id, firstName, lastName);
}
}
And a corresponding Order entity:
package hello;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
#Entity
public class Order {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
protected Order() {}
double amount;
#ManyToOne
Customer customer;
}
And the console output:

Thoughts?
TIA,

Try change your Order entity please:
package hello;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
#Entity
#Table(name = "order_table")
public class Order {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
protected Order() {}
double amount;
#ManyToOne
Customer customer;
}
Explanation:
Pay attention on #Table annotation. Using this annotation I've specified table name as order_table. In your case by default hibernate tried to generate table order. ORDER is service word in any sql. Exception appeared because hibernate was generating *** statement for the order table but db expected table name not service word order.
I had the exact same problem with an Order entity, solved defining explicitly the table name.
#Entity
#Table(name = "order_table")
class Order(
#Id
#GeneratedValue(generator = "system-uuid")
#GenericGenerator(name = "system-uuid", strategy = "uuid2")
val orderId: String,
val customerId: String,
...
)
I had the same issue with a column named order but I was unable to change it. Adding backticks to the column annotation solved it.
#Column(name = "`ORDER`")
val order: String
