方法详细资料
getOrder
public int getOrder()
从接口复制的说明:Ordered
Get the order value of this object.Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet
load-on-startup
values).Same order values will result in arbitrary sort positions for the affected objects.
- 指定者:
getOrder
在接口中Ordered
- 返回:
- the order value

,Ordered.LOWEST_PRECEDENCE
suspend
public void suspend()
从接口复制的说明:TransactionSynchronization
Suspend this synchronization. Supposed to unbind resources from TransactionSynchronizationManager if managing any.
resume
public void resume()
从接口复制的说明:TransactionSynchronization
Resume this synchronization. Supposed to rebind resources to TransactionSynchronizationManager if managing any.
flush
public void flush()
从接口复制的说明:TransactionSynchronization
Flush the underlying session to the datastore, if applicable: for example, a Hibernate/JPA session.- 指定者:

TransactionStatus.flush()
beforeCommit
public void beforeCommit(boolean readOnly) throws DataAccessException
从接口复制的说明:TransactionSynchronization
Invoked before transaction commit (before "beforeCompletion"). Can e.g. flush transactional O/R Mapping sessions to the database.This callback does not mean that the transaction will actually be committed. A rollback decision can still occur after this method has been called. This callback is rather meant to perform work that's only relevant if a commit still has a chance to happen, such as flushing SQL statements to the database.
Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.
- 指定者:
beforeCommit
在接口中TransactionSynchronization
- 参数:
readOnly
- whether the transaction is defined as read-only transaction- 抛出:
DataAccessException
- 另请参阅:
TransactionSynchronization.beforeCompletion()
beforeCompletion
public void beforeCompletion()
从接口复制的说明:TransactionSynchronization
Invoked before transaction commit/rollback. Can perform resource cleanup before transaction completion.This method will be invoked after
beforeCommit
, even whenbeforeCommit
threw an exception. This callback allows for closing resources before transaction completion, for any outcome.
afterCommit
public void afterCommit()
从接口复制的说明:TransactionSynchronization
Invoked after transaction commit. Can perform further operations right after the main transaction has successfully committed.Can e.g. commit further operations that are supposed to follow on a successful commit of the main transaction, like confirmation messages or emails.
NOTE: The transaction will have been committed already, but the transactional resources might still be active and accessible. As a consequence, any data access code triggered at this point will still "participate" in the original transaction, allowing to perform some cleanup (with no commit following anymore!), unless it explicitly declares that it needs to run in a separate transaction. Hence: Use
PROPAGATION_REQUIRES_NEW
for any transactional operation that is called from here.- 指定者:
afterCommit
在接口中TransactionSynchronization
afterCompletion
public void afterCompletion(int status)
从接口复制的说明:TransactionSynchronization
Invoked after transaction commit/rollback. Can perform resource cleanup after transaction completion.NOTE: The transaction will have been committed or rolled back already, but the transactional resources might still be active and accessible. As a consequence, any data access code triggered at this point will still "participate" in the original transaction, allowing to perform some cleanup (with no commit following anymore!), unless it explicitly declares that it needs to run in a separate transaction. Hence: Use
PROPAGATION_REQUIRES_NEW
for any transactional operation that is called from here.- 指定者:
afterCompletion
在接口中TransactionSynchronization
- 参数:
status
- completion status according to theSTATUS_*
constants- 另请参阅:
