I am tryna Delete the forgotPassword Enetity if the Otp expired time is passed out and that is 10 sec right now but after the Otp time expired the otp entity is not deleting itself from Db . Here is the implemet

if (forgotPassword.getOtpExpireDate().before(Date.from(Instant.now()))) {
            
            if (forgotPassword.getOtpExpireDate().before(Date.from(Instant.now()))) {
                
                 Long fId = forgotPassword.getForgotpasswordId();
                 System.out.println("The Password id is "+ fId);
                 
                emailService.deleteForgotPasswordById(fId);
                logger.warn("The Time is expired", forgotPassword.getOtpExpireDate());
                throw new OtpNotFoundExcpetion("Otp Expired");
            }
        }

if (forgotPassword.getOtpExpireDate().before(Date.from(Instant.now()))) {

dan1st•6mo ago

it's also possible to configure it to commit the transaction on that exception I think using noRollbackFor or similar

Tomasm21•6mo ago

The issue is due to relatioship guys. User had:

    @OneToOne(mappedBy = "user" , cascade = CascadeType.ALL)
    private ForgotPassword forgotPassword;

    @OneToOne(mappedBy = "user" , cascade = CascadeType.ALL)
    private ForgotPassword forgotPassword;

And ForgotPassword:

    @OneToOne
    @JoinColumn(name = "user_email" , nullable = false)
    private User user;

    @OneToOne
    @JoinColumn(name = "user_email" , nullable = false)
    private User user;

He can delete User and cascade to ForgotPassword But he can't delete ForgotPassword because of the reference. He tries, but it doesn't happen

Then why when on this method we have @Trabsactional and we delete the reference from user, save it to database, then delete the forgetPassword entity and at the end we throw an exception then I check the databse and see that it's deleted?

Showing a Spring transaction in log

I configured spring with transactional support. Is there any way to log transactions just to ensure I set up everything correctly? Showing in the log is a good way to see what is happening.

https://javadoc.io/doc/org.springframework/spring-tx/6.1.11/org/springframework/transaction/annotation/Transactional.html#rollbackFor()

dan1st•6mo ago

transactions are rolled back on unchecked exceptions (by default) cc @IncognitoBurrito @Tomasm21

Tomasm21•6mo ago

His exception that is thrown is this:

dan1st•6mo ago

which is rolled back if not stated otherwise

Tomasm21•6mo ago

I don't know wheret it is stated otherwise.

dan1st•6mo ago

so the exception undoes the deletion which I think was initially stated by IncognitoBurrito

Tomasm21•6mo ago

Danix was upset because he couldn't delete the entity anyhow. I read the info that in such a case we can manually nullify the reference in the parent entity and save it. Then we can delete the child entity. So the key was:

//.....
User userid = forgotPassword.getUser();
                System.out.println("USER BEFORE DELETION: "+userid.toString());
                // Remove the reference in the User entity
                userid.setForgotPassword(null);
                // Save the User entity to update the reference
                User savedUser = userRepository.save(userid);
                 
                System.out.println("SAVED USER: "+savedUser.toString());
                // emailService.deleteForgotPasswordById(fId);
                    
                logger.info("Deleting ForgotPassword entity with id: " + fId);
                forgotPasswordRepository.deleteById(fId);
//....

//.....
User userid = forgotPassword.getUser();
                System.out.println("USER BEFORE DELETION: "+userid.toString());
                // Remove the reference in the User entity
                userid.setForgotPassword(null);
                // Save the User entity to update the reference
                User savedUser = userRepository.save(userid);
                 
                System.out.println("SAVED USER: "+savedUser.toString());
                // emailService.deleteForgotPasswordById(fId);
                    
                logger.info("Deleting ForgotPassword entity with id: " + fId);
                forgotPasswordRepository.deleteById(fId);
//....

But now from experienced users I hear that it's nonsense and due to thrown exception the deletion cannot happen. The rollback should occur. If you are in the mood to investigate it and to prove that something special happened then you can invite me.

dan1st•6mo ago

such a rollback literally ensures the entity not being deleted and according in the stack trace, I don't see anything about the cascading issue as of when the OP posted the stack trace

Tomasm21•6mo ago

I have made Spring Console output. Currently deleting ugly looking symbols and soon will log you here. It's when transaction log is on. I don't know it. I learn it. Maybe you as more experienced will explain me.

Tomasm21•6mo ago

There:

jpa-text.txt

Tomasm21•6mo ago

The OP took my edited code. And is happy with it. Now the discussion object is that deletion cannot happen. The exception is not checked.

dan1st•6mo ago

That seems like there's no @Transactional active there

Tomasm21•6mo ago

Perhaps. I removed the annotation:

dan1st•6mo ago

Then you can't expect to reproduce what the OP is getting

Tomasm21•6mo ago

Ok. I will put the annotation back. And show the console.

Tomasm21•6mo ago

There:

jpa-text2.txt

Tomasm21•6mo ago

In both cases the entity was deleted. And I don't know of the rollback that should occur. Should I see it in the console output?

dan1st•6mo ago

that's because the whole thing is wrapped in a try-catch block I think but idk their code

Tomasm21•6mo ago

I had to put in a lot of efforts to get the rollback to work: I had to show specific criteria for the rollback:

    @PostMapping("/verify-otp")
    @Transactional(rollbackOn = OtpNotFoundExcpetion.class)
    public String verifyOtp(@RequestParam String otp , Model model , HttpSession session) {
//.....

    @PostMapping("/verify-otp")
    @Transactional(rollbackOn = OtpNotFoundExcpetion.class)
    public String verifyOtp(@RequestParam String otp , Model model , HttpSession session) {
//.....

Then throw this unchecked exception in the try block :

//.....
   forgotPasswordRepository.deleteById(fId);
   throw new OtpNotFoundExcpetion("Otp Expired");
}
//....

//.....
   forgotPasswordRepository.deleteById(fId);
   throw new OtpNotFoundExcpetion("Otp Expired");
}
//....

and to catch it in the catch block and to re-throw it:

catch (OtpNotFoundExcpetion e) {
     logger.error("The error occured", e);
     model.addAttribute("error", "Otp is Invalid");
    //return "otpchecker";
    throw e; // Re-throw to ensure transaction rollback
}

catch (OtpNotFoundExcpetion e) {
     logger.error("The error occured", e);
     model.addAttribute("error", "Otp is Invalid");
    //return "otpchecker";
    throw e; // Re-throw to ensure transaction rollback
}

Only then my transaction was rolled back and then entity was put back and undeleted. Damn.. lol

The rollbackOn = OtpNotFoundExcpetion.class wouldn't be necessary and just removing the catch(Exception) block would probably be sufficient

You are right. The rollback really occurs if there are no any try-catch blocks and with a single @Transactional annotation. Hibernate doesn't initiate the deletion at all. Then when we throw such unchecked exception then it rolls back. Now I will rememebr how to do it. But since our task is to show error messages in thymeleaf templates we will throw custom exceptions and will use try catch blocks. And we need to delete entity in specific circumstances. Thank you. This thread is over. To sum up everything, I see that nor @Transactional nor the throw of the exception and the rollback are not factors that prevented Danix way to delete the entity. If we don't do an exception and return a string (template) and we assign the error message model.addAttribute("error", "Otp Expired"); then the way Danix deletes his entity actually doesn't work here:

if (forgotPassword.getOtpExpireDate().before(Date.from(Instant.now()))) {
                
                Long fId = forgotPassword.getForgotpasswordId();
                System.out.println("The Password id is "+ fId);
                 
                User userid = forgotPassword.getUser();
                System.out.println("USER BEFORE DELETION: "+userid.toString());

                //userid.setForgotPassword(null);

                
                    
                logger.info("Deleting ForgotPassword entity with id: " + fId);
                //forgotPasswordRepository.deleteById(fId);
                emailService.deleteForgotPasswordById(fId);
                
                User savedUser = userRepository.findByEmail(userid.getEmail()).orElse(null);
                 
                System.out.println("USER AFTER DELETION: "+savedUser.toString());
                    
                logger.warn("The Time is expired: {} and now is: {}", forgotPassword.getOtpExpireDate(), Date.from(Instant.now()).toString());
                model.addAttribute("error", "Otp Expired");
                return "otpchecker";
//                throw new OtpNotFoundExcpetion("Otp Expired");
            }

if (forgotPassword.getOtpExpireDate().before(Date.from(Instant.now()))) {
                
                Long fId = forgotPassword.getForgotpasswordId();
                System.out.println("The Password id is "+ fId);
                 
                User userid = forgotPassword.getUser();
                System.out.println("USER BEFORE DELETION: "+userid.toString());

                //userid.setForgotPassword(null);

                
                    
                logger.info("Deleting ForgotPassword entity with id: " + fId);
                //forgotPasswordRepository.deleteById(fId);
                emailService.deleteForgotPasswordById(fId);
                
                User savedUser = userRepository.findByEmail(userid.getEmail()).orElse(null);
                 
                System.out.println("USER AFTER DELETION: "+savedUser.toString());
                    
                logger.warn("The Time is expired: {} and now is: {}", forgotPassword.getOtpExpireDate(), Date.from(Instant.now()).toString());
                model.addAttribute("error", "Otp Expired");
                return "otpchecker";
//                throw new OtpNotFoundExcpetion("Otp Expired");
            }

emailService.deleteForgotPasswordById(fId):

    @Transactional
    public void deleteForgotPasswordById(Long id) {
        log.info("Deleting ForgotPassword entity with id: " + id);
        forgotPasswordRepository.deleteById(id);
        log.info("Deleted ForgotPassword entity with id: " + id);
    }

    @Transactional
    public void deleteForgotPasswordById(Long id) {
        log.info("Deleting ForgotPassword entity with id: " + id);
        forgotPasswordRepository.deleteById(id);
        log.info("Deleted ForgotPassword entity with id: " + id);
    }

This doesn't make the ForgotPassword entity to be deleted.
