public @NotNull Connection acquire() throws DataAccessException

Implements org.jooq.ConnectionProvider.acquire.

Doc from org.jooq.ConnectionProvider.acquire.

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 release(Connection) exactly once.

Returns:@NotNull Connection

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.
