How do you unlock a domain object after calling lock ()?

Question

If you call lock() on a domain instance or statically in a class, and then you decide that nothing needs to be done with the object, is there a way to manually release the lock immediately?

Answer 1

To deploy dmahapatro , docs :

The lock is automatically released when the transaction commits.

therefore, as soon as you call .save() , the lock will be released when the transaction for this save completes (usually at the end of the service method).

You can also check out these docs .

Answer 2

The lock is released when the transaction is completed, but not when save () is called, because save () is still saved after saving the transaction. A transaction can be committed when the execution of the code leaves the service method or when the sleep session is reset (after the HTTP request is completed, the session is cleared and cleared).

The best way to release the lock is to use manual transaction processing. In this case, do the following:

 def saveUser(Long userId) { User.withNewTransaction { TransactionStatus status -> User user = User.lock(userId) user.save() } }
