• PERSISTENCE_MANAGER_SYNCHRONIZATION_ORDER

  public static final int PERSISTENCE_MANAGER_SYNCHRONIZATION_ORDER

  Order value for TransactionSynchronization objects that clean up JDO PersistenceManagers. Return DataSourceUtils.CONNECTION_SYNCHRONIZATION_ORDER - 100 to execute PersistenceManager cleanup before JDBC Connection cleanup, if any.

• getPersistenceManager

  public static javax.jdo.PersistenceManager getPersistenceManager​(javax.jdo.PersistenceManagerFactory pmf,
                                                                   boolean allowCreate)
                                                            throws DataAccessResourceFailureException,
                                                                   IllegalStateException

  Obtain a JDO PersistenceManager via the given factory. Is aware of a corresponding PersistenceManager bound to the current thread, for example when using JdoTransactionManager. Will create a new PersistenceManager else, if "allowCreate" is true.

  参数:

  pmf - PersistenceManagerFactory to create the PersistenceManager with

  allowCreate - if a non-transactional PersistenceManager should be created when no transactional PersistenceManager can be found for the current thread

  返回:

  the PersistenceManager

  抛出:

  DataAccessResourceFailureException - if the PersistenceManager couldn't be obtained

  IllegalStateException - if no thread-bound PersistenceManager found and "allowCreate" is false

• doGetPersistenceManager

  public static javax.jdo.PersistenceManager doGetPersistenceManager​(javax.jdo.PersistenceManagerFactory pmf,
                                                                     boolean allowCreate)
                                                              throws javax.jdo.JDOException,
                                                                     IllegalStateException

  Obtain a JDO PersistenceManager via the given factory. Is aware of a corresponding PersistenceManager bound to the current thread, for example when using JdoTransactionManager. Will create a new PersistenceManager else, if "allowCreate" is true.

  Same as getPersistenceManager, but throwing the original JDOException.

  参数:

  pmf - PersistenceManagerFactory to create the PersistenceManager with

  allowCreate - if a non-transactional PersistenceManager should be created when no transactional PersistenceManager can be found for the current thread

  返回:

  the PersistenceManager

  抛出:

  javax.jdo.JDOException - if the PersistenceManager couldn't be created

  IllegalStateException - if no thread-bound PersistenceManager found and "allowCreate" is false

• isPersistenceManagerTransactional

  public static boolean isPersistenceManagerTransactional​(javax.jdo.PersistenceManager pm,
                                                          javax.jdo.PersistenceManagerFactory pmf)

  Return whether the given JDO PersistenceManager is transactional, that is, bound to the current thread by Spring's transaction facilities.

  参数:

  pm - the JDO PersistenceManager to check

  pmf - JDO PersistenceManagerFactory that the PersistenceManager was created with (can be null)

  返回:

  whether the PersistenceManager is transactional

• applyTransactionTimeout

  public static void applyTransactionTimeout​(javax.jdo.Query query,
                                             javax.jdo.PersistenceManagerFactory pmf)
                                      throws javax.jdo.JDOException

  Apply the current transaction timeout, if any, to the given JDO Query object.

  参数:

  query - the JDO Query object

  pmf - JDO PersistenceManagerFactory that the Query was created for

  抛出:

  javax.jdo.JDOException - if thrown by JDO methods

• convertJdoAccessException

  public static DataAccessException convertJdoAccessException​(javax.jdo.JDOException ex)

  Convert the given JDOException to an appropriate exception from the org.springframework.dao hierarchy.

  The most important cases like object not found or optimistic locking failure are covered here. For more fine-granular conversion, JdoTransactionManager supports sophisticated translation of exceptions via a JdoDialect.

  参数:

  ex - JDOException that occured

  返回:

  the corresponding DataAccessException instance

• releasePersistenceManager

  public static void releasePersistenceManager​(javax.jdo.PersistenceManager pm,
                                               javax.jdo.PersistenceManagerFactory pmf)

  Close the given PersistenceManager, created via the given factory, if it is not managed externally (i.e. not bound to the thread).

  参数:

  pm - PersistenceManager to close

  pmf - PersistenceManagerFactory that the PersistenceManager was created with (can be null)

• doReleasePersistenceManager

  public static void doReleasePersistenceManager​(javax.jdo.PersistenceManager pm,
                                                 javax.jdo.PersistenceManagerFactory pmf)
                                          throws javax.jdo.JDOException

  Actually release a PersistenceManager for the given factory. Same as releasePersistenceManager, but throwing the original JDOException.

  参数:

  pm - PersistenceManager to close

  pmf - PersistenceManagerFactory that the PersistenceManager was created with (can be null)

  抛出:

  javax.jdo.JDOException - if thrown by JDO methods
