- org.springframework.transaction.support.DefaultTransactionDefinition

所有已实现的接口:
Serializable, TransactionDefinition
直接已知子类:
DefaultTransactionAttribute, TransactionTemplate
```
public class DefaultTransactionDefinition
extends Object
implements TransactionDefinition, Serializable
```
Default implementation of the TransactionDefinition interface, offering bean-style configuration and sensible default values (PROPAGATION_REQUIRED, ISOLATION_DEFAULT, TIMEOUT_DEFAULT, readOnly=false).
Base class for both TransactionTemplate and DefaultTransactionAttribute.

```
    Set the propagation behavior by the name of the corresponding constant in TransactionDefinition, e.g. "PROPAGATION_REQUIRED".
    参数:
    constantName - name of the constant
    抛出:

```
public final void setPropagationBehavior(int propagationBehavior)
```
    Set the propagation behavior. Must be one of the propagation constants in the TransactionDefinition interface. Default is PROPAGATION_REQUIRED.
    Exclusively designed for use with TransactionDefinition.PROPAGATION_REQUIRED or TransactionDefinition.PROPAGATION_REQUIRES_NEW since it only applies to newly started 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.
    Note that a transaction manager that does not support custom isolation levels will throw an exception when given any other level than TransactionDefinition.ISOLATION_DEFAULT.

    Return the isolation level.
    Must return one of the ISOLATION_XXX constants defined on this interface. Those constants are designed to match the values of the same constants on Connection.
    Exclusively designed for use with TransactionDefinition.PROPAGATION_REQUIRED or TransactionDefinition.PROPAGATION_REQUIRES_NEW since it only applies to newly started 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.

  - setTimeout

    Set the timeout to apply, as number of seconds. Default is TIMEOUT_DEFAULT (-1).
    Exclusively designed for use with TransactionDefinition.PROPAGATION_REQUIRED or TransactionDefinition.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 TransactionDefinition.TIMEOUT_DEFAULT.

    the transaction timeout
  - setReadOnly
```
public final 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 (TransactionDefinition.PROPAGATION_REQUIRED/ TransactionDefinition.PROPAGATION_REQUIRES_NEW) or operating non-transactionally at the resource level (TransactionDefinition.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.
  - isReadOnly
```
public final boolean isReadOnly()
```
    从接口复制的说明: TransactionDefinition
    Return whether to optimize as a read-only transaction.

  - setName
```
public final 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).
  - getName
```
public final String getName()
```
    从接口复制的说明: TransactionDefinition
    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 TransactionDefinition
    返回:
    the name of this transaction

  - equals
```
public boolean equals(Object other)
```
    This implementation compares the toString() results.

  - toString
```
public String toString()
```
    Return an identifying description for this transaction definition.
    The format matches the one used by TransactionAttributeEditor, to be able to feed toString results into bean properties of type TransactionAttribute.
    Has to be overridden in subclasses for correct equals and hashCode behavior. Alternatively, equals(java.lang.Object) and hashCode() can be overridden themselves.
    覆盖:
    toString 在类中 Object
    另请参阅:
    getDefinitionDescription(), TransactionAttributeEditor
  - getDefinitionDescription
```
protected final StringBuilder getDefinitionDescription()
```
    Return an identifying description for this transaction definition.
    Available to subclasses, for inclusion in their toString() result.
