DefaultTransactionDefine

public DefaultTransactionDefine()

Create a new DefaultTransactionDefinition, with default settings. Can be modified through bean property setters.

setTimeout(int), setReadOnly(boolean), setName(java.lang.String)

DefaultTransactionDefine

public DefaultTransactionDefine(TransactionDefine other)

Copy constructor. Definition can be modified through bean property setters.

setTimeout(int), setReadOnly(boolean), setName(java.lang.String)

DefaultTransactionDefine

public DefaultTransactionDefine(int propagationBehavior)

Create a new DefaultTransactionDefinition with the given propagation behavior. Can be modified through bean property setters.

参数:

propagationBehavior - one of the propagation constants in the TransactionDefinition interface

方法详细资料

getPropagationBehavior

public final int getPropagationBehavior()

从接口复制的说明: TransactionDefine

Return the propagation behavior.

Must return one of the PROPAGATION_XXX constants

The default is TransactionDefine.PROPAGATION_REQUIRED.

指定者:

getPropagationBehavior 在接口中 TransactionDefine

返回:

the propagation behavior

另请参阅:

TransactionDefine.PROPAGATION_REQUIRED

getPropagationBehaviorName

public String getPropagationBehaviorName()

指定者:

getPropagationBehaviorName 在接口中 TransactionDefine

getIsolationLevel

public final int getIsolationLevel()

从接口复制的说明: TransactionDefine

Return the isolation level.

Must return one of the ISOLATION_XXX constants defined on

Exclusively designed for use with TransactionDefine.PROPAGATION_REQUIRED or transactions. Consider switching the "validateExistingTransactions" flag to "true" on your transaction manager if you'd like isolation level declarations to get rejected when participating in an existing transaction with a different isolation level.

The default is TransactionDefine.ISOLATION_DEFAULT. Note that a transaction manager that does not support custom isolation levels will throw an exception when given any other level than TransactionDefine.ISOLATION_DEFAULT.

指定者:

getIsolationLevel 在接口中 TransactionDefine

返回:

the isolation level

setTimeout

public void setTimeout(int timeout)

Set the timeout to apply, as number of seconds. Default is TIMEOUT_DEFAULT (-1).

Exclusively designed for use with TransactionDefine.PROPAGATION_REQUIRED or TransactionDefine.PROPAGATION_REQUIRES_NEW since it only applies to newly started transactions.

Note that a transaction manager that does not support timeouts will throw an exception when given any other timeout than TransactionDefine.TIMEOUT_DEFAULT.

指定者:

setTimeout 在接口中 TransactionDefine

另请参阅:

TransactionDefine.TIMEOUT_DEFAULT

getTimeout

public final int getTimeout()

从接口复制的说明: TransactionDefine

Return the transaction timeout.

Must return a number of seconds, or TransactionDefine.TIMEOUT_DEFAULT.

Exclusively designed for use with TransactionDefine.PROPAGATION_REQUIRED or TransactionDefine.PROPAGATION_REQUIRES_NEW since it only applies to newly started transactions.

Note that a transaction manager that does not support timeouts will throw an exception when given any other timeout than TransactionDefine.TIMEOUT_DEFAULT.

The default is TransactionDefine.TIMEOUT_DEFAULT.

指定者:

getTimeout 在接口中 TransactionDefine

返回:

the transaction timeout

setReadOnly

public void setReadOnly(boolean readOnly)

Set whether to optimize as read-only transaction. Default is "false".

The read-only flag applies to any transaction context, whether backed by an actual resource transaction (TransactionDefine.PROPAGATION_REQUIRED/ TransactionDefine.PROPAGATION_REQUIRES_NEW) or operating non-transactionally at the resource level (TransactionDefine.PROPAGATION_SUPPORTS). In the latter case, the flag will only apply to managed resources within the application, such as a Hibernate Session.

This just serves as a hint for the actual transaction subsystem; it will not necessarily cause failure of write access attempts. A transaction manager which cannot interpret the read-only hint will not throw an exception when asked for a read-only transaction.

指定者:

setReadOnly 在接口中 TransactionDefine

isReadOnly

public final boolean isReadOnly()

从接口复制的说明: TransactionDefine

Return whether to optimize as a read-only transaction.

The read-only flag applies to any transaction context, whether backed by an actual resource transaction (TransactionDefine.PROPAGATION_REQUIRED/ TransactionDefine.PROPAGATION_REQUIRES_NEW) or operating non-transactionally at the resource level (TransactionDefine.PROPAGATION_SUPPORTS). In the latter case, the flag will only apply to managed resources within the application, such as a Hibernate Session.

This just serves as a hint for the actual transaction subsystem; it will not necessarily cause failure of write access attempts. A transaction manager which cannot interpret the read-only hint will not throw an exception when asked for a read-only transaction.

指定者:

isReadOnly 在接口中 TransactionDefine

返回:

true if the transaction is to be optimized as read-only (false by default)

setName

public void setName(String name)

Set the name of this transaction. Default is none.

This will be used as transaction name to be shown in a transaction monitor, if applicable (for example, WebLogic's).

指定者:

setName 在接口中 TransactionDefine

getName

public String getName()

从接口复制的说明: TransactionDefine

Return the name of this transaction. Can be null.

This will be used as the transaction name to be shown in a transaction monitor, if applicable (for example, WebLogic's).

In case of Spring's declarative transactions, the exposed name will be the fully-qualified class name + "." + method name (by default).

指定者:

getName 在接口中 TransactionDefine

返回:

the name of this transaction (null by default}

getMode

public TransactionDefine.MODE getMode()

指定者:

getMode 在接口中 TransactionDefine

setMode

public void setMode(TransactionDefine.MODE mode)

指定者:

setMode 在接口中 TransactionDefine
