Interface TransactionProvider

All Known Implementing Classes:

DefaultTransactionProvider, NoTransactionProvider, ThreadLocalTransactionProvider

public interface TransactionProvider

The TransactionProvider SPI can be used to implement custom transaction behaviour that is applied when calling DSLContext.transactionResult(TransactionalCallable) or DSLContext.transaction(TransactionalRunnable).

A new Configuration copy is created from the calling DSLContext for the scope of a single transactions. Implementors may freely add custom data to Configuration.data(), in order to share information between begin(TransactionContext) and commit(TransactionContext) or rollback(TransactionContext), as well as to share information with nested transactions.

Implementors may freely choose whether they support nested transactions. An example implementation supporting nested transactions is DefaultTransactionProvider, which implements such transactions using JDBC Savepoints.

Method Details

begin

void begin(TransactionContext ctx)
    throws DataAccessException

Begin a new transaction.

This method begins a new transaction with a Configuration scoped for this transaction. The resulting Transaction object may be used by implementors to identify the transaction when commit(TransactionContext) or rollback(TransactionContext) is called.

Parameters:

ctx - the configuration scoped to this transaction and its nested transactions.

Throws:

DataAccessException - Any exception issued by the underlying database.

commit

void commit(TransactionContext ctx)
     throws DataAccessException

Commit a transaction.

Parameters:

ctx - the configuration scoped to this transaction and its nested transactions.

Throws:

DataAccessException - Any exception issued by the underlying database.

rollback

void rollback(TransactionContext ctx)
       throws DataAccessException

Rollback a transaction.

Parameters:

ctx - the configuration scoped to this transaction and its nested transactions.

Throws:

DataAccessException - Any exception issued by the underlying database.
