org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'unitRepository' defined in com.fidolease.fidolease.repository.UnitRepository defined in #EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot resolve reference to bean 'jpaMappingContext' while setting bean property 'mappingContext'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister
When I searched around, it seemed as if the error might occur if I don't have JPA in my pom file but after searching it, I have the following:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
Does anyone have any suggestions as to what I am doing wrong here or maybe a reference to some documentation that may explain my issue? Thank you all for your time and if there is anything I can do to clarify, please let me know.
EDIT: The following is my properties file:
spring.datasource.initialization-mode=always

There is a bug in your setter method for unit_number, it is not taking a parameter. It should be:
public void setUnit_number(String unit_number){
this.unit_number = unit_number;
}

Postman changes all number values to 0

I've been looking around for a bit and can't seem to figure out why this happens.
I made a post request in postman, it runs it, intelliJ's console doesn't display an error, yet when printing out the object, it shows only the name has been inserted as I wrote it, the rest are 0's.
EDIT: numbers now come in, but foreign key "holdid" only returns as a null value
EDIT 2: Made it work, code changed to show working code

Any help is appreciated, thank you!

For JSON deserialization, Jackson is case sensitive to find the Java fields for each of the fields in the JSON body. In your case, the Java field names are not the same as the JSON field names. You either have to rename them in one of the sides, or add the JsonProperty annotation to tell Jackson, what the field is called in the JSON body.
Example:
#Column(name = "bjergpoint")
#JsonProperty("bjergpoint")
private int bjergPoint;

If two entity parent and child saved at same time which mapped with one to many relationship throw id not found exception of parent class

My relationship like this which is shown in image :
enter image description here
I'm having troubling with insert data in database because of bill id saved little bit late and that time also buybill save simultaneously in database and which want to bill id to save in relationship and throw exception like invoice id not found and only my bill data saved in database and buybill thrwo exception of not found bill id so please help me out.
Thanks,
And one more thing that i include that my postmapping of :
This--->
#PostMapping(value="/customers/{customerId}/bills/{InvoiceNo}/buyBills",produces="application/json",consumes="application/json")
and
This--->
#PostMapping(value="/customers/{customerId}/bills/{InvoiceNo}/bills",produces="application/json",consumes="application/json")

Main problem ::
In Brief Bill id in "BillRepository.findById(InvoiceNo)" is empty when both bill and buybill save simultaneously.

I notice that in Bill you have #generatedValue on invoiceId. I don't think you can use #generatedValue on a non #Id field. See this post.

I assume your exception occurs at this point?
// return BillRepository.findById(InvoiceNo).map(bills -> {
// buyBill.setBill(bills);
// buyBillRepository.save(buyBill);
// ModelAndView mv = new ModelAndView("redirect:/cust/customersBuyBill/{customerId}"); return mv;
// }).orElseThrow(() -> new NotFoundException("Invoice No not found!"));
If so then you try to find a Bill by id (BillRepository.findById) but providing a invoiceNo instead of the concrete id
repository.findById refers to the #Id annotated column. In your case:
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
Therefore you need to use / implement the method findByInvoiceNo to get your concrete Bill by the provided invoiceNo instead of findById
Edit
Your Bill repository shall contain this method
public interface BillRepository extends JpaRepository<Bill, Long> {
Bill findByInvoiceNo(String invoiceNo);
}
and then
return BillRepository.findB<InvoiceNo(InvoiceNo).map(bills -> {
buyBill.setBill(bills);
buyBillRepository.save(buyBill);
ModelAndView mv = new ModelAndView("redirect:/cust/customersBuyBill/{customerId}"); return mv;
}).orElseThrow(() -> new NotFoundException("Invoice No not found!"));
Edit #2
#PostMapping(value="/customers/{customerId}/bills/{invoiceNo}/buyBills",produces="application/json",consumes="application/json")
#ResponseBody
public ModelAndView addBuyBillRequest(#PathVariable Long customerId, #PathVariable Long invoiceNo,#Valid #RequestBody BuyBill buyBill){
System.out.println(invoiceNo);
System.out.println(BillRepository.findByinvoiceNo(invoiceNo));
return BillRepository.findByinvoiceNo(invoiceNo).map(bills -> {
buyBill.setBill(bills);
buyBillRepository.save(buyBill);
ModelAndView mv = new ModelAndView("redirect:/cust/customersBuyBill/{customerId}"); return mv;
}).orElseThrow(() -> new NotFoundException("Invoice No not found!"));
}
Shouldn't it be
return BillRepository.findByinvoiceNo(invoiceNo).map(bills -> {
bills.addBuyBill(buyBill);
billsRepository.save(bills);
and in the Bill class:
public class Bill implements Serializable {
public void addBuyBill(BuyBill buyBill) {
this.BuyBill.add(buyBill);
buyBill.setBill(this)
}
}
Same goes for this part
return customerRepository.findById(customerId) .map(customer -> {
bill.setCustomer(customer);
BillRepository.save(bill);
ModelAndView mv = new ModelAndView("redirect:/cust/customersBuyBill/{customerId}");
return mv;
}).orElseThrow(() -> new NotFoundException("Customer not found!"));
}
As customer holds none or more bills you need to add a synchronization method like before:
return customerRepository.findById(customerId) .map(customer -> {
customer.addBill(bill);
CustomerRepository.save(customer);
ModelAndView mv = new ModelAndView("redirect:/cust/customersBuyBill/{customerId}");
return mv;
}).orElseThrow(() -> new NotFoundException("Customer not found!"));
}
And in customer
public class Customer implements Serializable {
public void addBill(Bill newBill) {
this.Bill.add(newBill);
newBill.setCustomer(this)
}
}
As you are using a bi-directional association you should keep them synchronized. Otherwise the state transitions of the entities may not work.
Sorry for the long term investigation. But the code makes it hard to identify.
You should definitely think about some refactoring. But this would go beyond the scope of this question.

I've already tried to change the name of SocietyBlockFloor.societyBlockFloorId, but then in the ON clause it still uses (society.societyId = societyBlockFloor.societyId) where societyBlockFloor.societyId doesn't exist.

you have a repeated column in the mapping. You mapped the same database column twice. you have:
#Id
#Column(name="society_id")
private String societyBlockFloorId;
And
#ManyToOne
#JoinColumn(name = "society_id", nullable = false)
private SocietyDetails societyDetails;
This seems useless
#Id
#Column(name="society_id")
private String societyBlockFloorId;
If you want societyid just ask to societyDetails.getId();
And this on the manyToOne side
referencedColumnName = "society_id"

I don't want to generate history and audit table for ProductNote.

I m new to Springs, Hibernate and REST API.
How can i catch org.hibernate.exception.ConstraintViolationException ( I do not want to delete the mill data since you have dependent(child) data on the mill and display a appropriate msg to user that it cannot delete it due to orders exists for the mill.
Please Help.

Basically you have to handle the Exception. Introduce a try catch block and output the appropriate message.
Handle the exception at the base level and funnel it to the controller.
