Display valid msg to user for org.hibernate.exception.ConstraintViolationException: - java

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.
Thank you
Here is my Code.
MillResource.java

log.debug("REST request to delete Mill : {}", id);
millRepository.delete(id);
log.debug(" ", id);
return ResponseEntity.ok().headers(HeaderUtil.createEntityDeletionAlert("mill", id.toString())).build();
}
CrudRepository
void delete(ID id);
/**

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.

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.

In my humble opinion, there are a couple of things to check.
First, it isn't recommended to use the same object to store data in your database and response a request. The data object could be GangUser, User and Gang, while the response objects GangUserApi, UserApi, and GangApi. With this approach, you'll be able to amend a layer without modifying another.
Second, your service is expecting a GangUser with a User inside. The same User Object that you use to store it in the database. You're just sending a String ("1") instead of an object there.
A quick solution could be modifying the JSON:
{
"role": "member",
"gang": "3",
"user": {
"id":"1"
}
}
But I would like to know if you understand what was going on. That is more important than just give you a quick solution.
Cheers.

spring boot rest for one to many relation

I created spring boot project where I am making rest application. I have used My SQL database and I am using spring data. There is one method which adds orders based on customer id. So I am not able to figure out it will work based on spring data query or custom query and how it will be?
I have attached required codes only,

How should I design this addOrders method?

If you are using Spring Data then you will need to create a CrudRepository for each table you which to access. The CrudRepository allows you to easily manipulate data in your table using standard ORM practices. Here is a link with more details.
For more detailed info on how to use Spring Data check out this wonderful guide. This guide has become indispensable when working with Spring Data.

There are many options to this but i have used below approach so hope it helps you. The #Query annotation allows to execute native queries by setting the nativeQuery flag to true.
#Query(value = "select o.* from customer c inner join order o on c.customer_id = o.customer_id where o. = ?1", nativeQuery = true)
Please write sql according to your requirement.

SPRING JPA - org.hibernate.PersistentObjectException: detached entity passed to persist:

I've been stuck here for almost a week trying find the answer on the internet but sadly nothing worked. :( Everytime I try to update using this method:
private Tenant updateTenantWithApplicationProperties(List<TenantApplicationProperty> newTenantApplicationProperties, String tenantId) {
String reason = "Update application properties.";
Tenant existingTenant = tenantRepository.findById(tenantId);
List<TenantApplicationProperty> temp = existingTenant.getTenantApplicationProperties();
existingTenant.setTenantApplicationProperties(newTenantApplicationProperties);
setApplicationPropertiesUpdateValues(temp, existingTenant);
if(newTenantApplicationProperties != null && newTenantApplicationProperties.size() != 0) {
Tenant savedTenantWithAppProps = saveTenantWithLog(existingTenant, reason);
return savedTenantWithAppProps;
}
return existingTenant;
}
Im always getting this error:
javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist: com.infor.ecom.tenant.manager.model.entity.ApplicationProperty

But when Im using this method it works fine:

List<Database> databases = tenant.getDatabases();
List<Administrator> administrators = tenant.getAdministrators();
validateUpdateTenant(tenant);
validateDatabases(databases);
validateAdministrators(administrators);
Tenant existingTenant = findByIdWithAllDetails(tenant.getId());
List<Database> listExistingDatabases = existingTenant.getDatabases();
Database existingEcomDb = getDatabaseByType(listExistingDatabases,
TenantManagerConstants.ECOM_DATASOURCE);
setDatabaseUpdateValues(listExistingDatabases, tenant);
setAdministratorsUpdateValues(existingTenant.getAdministrators(),
tenant);
setProductUpdateValue(existingTenant.getProduct(), tenant);
setApplicationPropertiesUpdateValues(existingTenant.getTenantApplicationProperties(), tenant);
setEcomDBParamsDefaultValues(tenant);
setAdministratorDefaultValues(tenant);
Database updateEcomDb = getDatabaseByType(tenant.getDatabases(),
TenantManagerConstants.ECOM_DATASOURCE);
Boolean shouldInstallNewDB = true;
if (existingEcomDb.getName().equalsIgnoreCase(updateEcomDb.getName())
&& existingEcomDb.getHost().equalsIgnoreCase(
updateEcomDb.getHost())
&& existingEcomDb.getPort().equals(updateEcomDb.getPort())) {
shouldInstallNewDB = false;
} else {
testEcomDBConnection(updateEcomDb);
}
int ecomDbTableCount = getEcomDBTableCount(updateEcomDb);
String[][] languages = formatAndValidateLanguages(updateEcomDb
.getEcomDatabaseParameters().getLanguages());
Tenant updatedTenant = saveExistingTenant(tenant);
if (updatedTenant != null) {
if (shouldInstallNewDB || ecomDbTableCount == 0) {
installDatabase(updateEcomDb, languages, updatedTenant);
} else {
updateDatabase(updateEcomDb, languages, updatedTenant);
}
storageService.updateTenantFolderStructure(updatedTenant);
} else {
throw new TenantManagerException(

In application property, you defined 1-1 relation like:
#OneToOne
#JoinColumn(name = "property_group_id")
private ApplicationPropertyGroup applicationPropertyGroup;
#OneToOne
#JoinColumn(name = "property_type_id")
private ApplicationPropertyType applicationPropertyType;
While you have not defined the same relation (note it should work bidirectionally i.e. say for e.g. if you as a person related to an employee id, then employee id is related to you as a person well) in individual property ApplicationPropertyGroup and ApplicationPropertyType.
You should add the same 1-1 relation in ApplicationPropertyGroup and ApplicationPropertyType with ApplicationProperty.
