Constructor Details

CompositeTransactionAttributeSource

public CompositeTransactionAttributeSource(TransactionAttributeSource... transactionAttributeSources)

Create a new CompositeTransactionAttributeSource for the given sources.

Parameters:

transactionAttributeSources - the TransactionAttributeSource instances to combine

Method Details

getTransactionAttributeSources

public final TransactionAttributeSource[] getTransactionAttributeSources()

Return the TransactionAttributeSource instances that this CompositeTransactionAttributeSource combines.

isCandidateClass

public boolean isCandidateClass(Class<?> targetClass)

Description copied from interface: TransactionAttributeSource

Determine whether the given class is a candidate for transaction attributes in the metadata format of this TransactionAttributeSource.

If this method returns false, the methods on the given class will not get traversed for TransactionAttributeSource.getTransactionAttribute(java.lang.reflect.Method, java.lang.Class<?>) introspection. Returning false is therefore an optimization for non-affected classes, whereas true simply means that the class needs to get fully introspected for each method on the given class individually.

Specified by:

isCandidateClass in interface TransactionAttributeSource

Parameters:

targetClass - the class to introspect

Returns:

false if the class is known to have no transaction attributes at class or method level; true otherwise. The default implementation returns true, leading to regular introspection.

hasTransactionAttribute

public boolean hasTransactionAttribute(Method method,
 @Nullable
 Class<?> targetClass)

Description copied from interface: TransactionAttributeSource

Determine whether there is a transaction attribute for the given method.

Specified by:

hasTransactionAttribute in interface TransactionAttributeSource

Parameters:

method - the method to introspect

targetClass - the target class (can be null, in which case the declaring class of the method must be used)

getTransactionAttribute

@Nullable
public TransactionAttribute getTransactionAttribute(Method method,
 @Nullable
 Class<?> targetClass)

Description copied from interface: TransactionAttributeSource

Return the transaction attribute for the given method, or null if the method is non-transactional.

Specified by:

getTransactionAttribute in interface TransactionAttributeSource

Parameters:

method - the method to introspect

targetClass - the target class (can be null, in which case the declaring class of the method must be used)

Returns:

the matching transaction attribute, or null if none found
