Class DefaultConnectionProvider

java.lang.Object

org.jooq.impl.DefaultConnectionProvider

All Implemented Interfaces:

ConnectionProvider

public class DefaultConnectionProvider
extends Object
implements ConnectionProvider

A default implementation for ConnectionProvider.

This implementation just wraps a JDBC Connection and provides jOOQ with the same connection for every query. jOOQ will not call any transaction-related methods on the supplied connection. Instead, jOOQ provides you with convenient access to those methods, wrapping any checked SQLException into an unchecked DataAccessException

Method Details

acquire

@NotNull
public final @NotNull Connection acquire()

Description copied from interface: ConnectionProvider

Acquire a connection from the connection lifecycle handler.

This method is called by jOOQ exactly once per execution lifecycle, i.e. per ExecuteContext. Implementations may freely chose, whether subsequent calls to this method:

• return the same connection instance
• return the same connection instance for the same thread
• return the same connection instance for the same transaction (e.g. a javax.transaction.UserTransaction)
• return a fresh connection instance every time

jOOQ will guarantee that every acquired connection is released through ConnectionProvider.release(Connection) exactly once.

Specified by:

acquire in interface ConnectionProvider

Returns:

A connection for the current ExecuteContext. If null is returned (e.g. by NoConnectionProvider), then statements cannot be executed. Attempts to execute statements will result in a DetachedException.

release

public final void release(Connection released)

Description copied from interface: ConnectionProvider

Release a connection to the connection lifecycle handler.

jOOQ will guarantee that every acquired connection is released exactly once.

Specified by:

release in interface ConnectionProvider

Parameters:

released - A connection that was previously obtained from ConnectionProvider.acquire(). This is never null.
