Method Details

doBegin

protected void doBegin(DefaultTransactionStatus<org.hibernate.Session> txStatus)

Description copied from class: AbstractTransactionOperations

Begin a new transaction with semantics according to the given transaction definition. Does not have to care about applying the propagation behavior, as this has already been handled by this abstract manager.

This method gets called when the transaction manager has decided to actually start a new transaction. Either there wasn't any transaction before, or the previous transaction has been suspended.

Specified by:

doBegin in class AbstractTransactionOperations<DefaultTransactionStatus<org.hibernate.Session>,org.hibernate.Session>

Parameters:

txStatus - The transaction

doCommit

protected void doCommit(DefaultTransactionStatus<org.hibernate.Session> tx)

Description copied from class: AbstractTransactionOperations

Perform an actual commit of the given transaction.

An implementation does not need to check the "new transaction" flag or the rollback-only flag; this will already have been handled before. Usually, a straight commit will be performed on the transaction object contained in the passed-in status.

Specified by:

doCommit in class AbstractTransactionOperations<DefaultTransactionStatus<org.hibernate.Session>,org.hibernate.Session>

Parameters:

tx - The transaction

doRollback

protected void doRollback(DefaultTransactionStatus<org.hibernate.Session> tx)

Description copied from class: AbstractTransactionOperations

Perform an actual rollback of the given transaction.

An implementation does not need to check the "new transaction" flag; this will already have been handled before. Usually, a straight rollback will be performed on the transaction object contained in the passed-in status.

Specified by:

doRollback in class AbstractTransactionOperations<DefaultTransactionStatus<org.hibernate.Session>,org.hibernate.Session>

Parameters:

tx - The transaction

getConnection

@NonNull
public @NonNull org.hibernate.Session getConnection()

Description copied from interface: TransactionOperations

Obtains the connection for the current transaction.

Returns:

The connection

hasConnection

@NonNull
public @io.micronaut.core.annotation.NonNull boolean hasConnection()

Description copied from interface: TransactionOperations

Check if the connection exists.

Specified by:

hasConnection in interface TransactionOperations<org.hibernate.Session>

Overrides:

hasConnection in class AbstractTransactionOperations<DefaultTransactionStatus<org.hibernate.Session>,org.hibernate.Session>

Returns:

True if transaction exists
