Class JtaAwareConnectionProviderImpl

java.lang.Object
org.hibernate.testing.jta.JtaAwareConnectionProviderImpl
All Implemented Interfaces:
Serializable, ConnectionProvider, Service, Configurable, ServiceRegistryAwareService, Stoppable, Wrapped
public class JtaAwareConnectionProviderImpl extends Object implements ConnectionProvider, Configurable, Stoppable, ServiceRegistryAwareService
A ConnectionProvider implementation intended for testing Hibernate/JTA interaction. In that limited scope we only ever have one single resource (the database connection) so we do not at all care about full-blown XA semantics. This class behaves accordingly. This class also assumes usage of and access to JBossTS/Arjuna.

    • getConnection

      public Connection getConnection() throws SQLException
      Description copied from interface: ConnectionProvider
      Obtains a connection for Hibernate use according to the underlying strategy of this provider.
      Specified by:
      getConnection in interface ConnectionProvider
      Returns:
      The obtained JDBC connection
      Throws:
      SQLException - Indicates a problem opening a connection

    • closeConnection

      public void closeConnection(Connection connection) throws SQLException
      Description copied from interface: ConnectionProvider
      Release a connection from Hibernate use.
      Specified by:

      Parameters:
      connection - The JDBC connection to release
      Throws:
      SQLException - Indicates a problem closing the connection

    • supportsAggressiveRelease

      public boolean supportsAggressiveRelease()
      Description copied from interface: ConnectionProvider
      Does this connection provider support aggressive release of JDBC connections and later re-acquisition of those connections if needed?

      This is used in conjunction with ConnectionReleaseMode.AFTER_STATEMENT to aggressively release JDBC connections. However, the configured ConnectionProvider must support re-acquisition of the same underlying connection for that semantic to work.

      Typically, this is only true in managed environments where a container tracks connections by transaction or thread.

      Note that JTA semantic depends on the fact that the underlying connection provider does support aggressive release.

      Specified by:
      supportsAggressiveRelease in interface ConnectionProvider
      Returns:
      true if aggressive releasing is supported; false otherwise.
