Class AnnotationTransactionAttributeSource

java.lang.Object

org.springframework.transaction.interceptor.AbstractFallbackTransactionAttributeSource

org.springframework.transaction.annotation.AnnotationTransactionAttributeSource

All Implemented Interfaces:

Serializable, TransactionAttributeSource

public class AnnotationTransactionAttributeSource
extends AbstractFallbackTransactionAttributeSource
implements Serializable

Implementation of the TransactionAttributeSource interface for working with transaction metadata in JDK 1.5+ annotation format.

This class reads Spring's JDK 1.5+ Transactional annotation and exposes corresponding transaction attributes to Spring's transaction infrastructure. Also supports JTA 1.2's Transactional and EJB3's TransactionAttribute annotation (if present). This class may also serve as base class for a custom TransactionAttributeSource, or get customized through TransactionAnnotationParser strategies.

Since:

1.2

Constructor Detail

AnnotationTransactionAttributeSource

public AnnotationTransactionAttributeSource()

Create a default AnnotationTransactionAttributeSource, supporting public methods that carry the Transactional annotation or the EJB3 TransactionAttribute annotation.

AnnotationTransactionAttributeSource

public AnnotationTransactionAttributeSource(boolean publicMethodsOnly)

Create a custom AnnotationTransactionAttributeSource, supporting public methods that carry the Transactional annotation or the EJB3 TransactionAttribute annotation.

Parameters:

publicMethodsOnly - whether to support public methods that carry the Transactional annotation only (typically for use with proxy-based AOP), or protected/private methods as well (typically used with AspectJ class weaving)

AnnotationTransactionAttributeSource

public AnnotationTransactionAttributeSource(TransactionAnnotationParser annotationParser)

Create a custom AnnotationTransactionAttributeSource.

Parameters:

annotationParser - the TransactionAnnotationParser to use

AnnotationTransactionAttributeSource

public AnnotationTransactionAttributeSource(TransactionAnnotationParser... annotationParsers)

Create a custom AnnotationTransactionAttributeSource.

Parameters:

annotationParsers - the TransactionAnnotationParsers to use

AnnotationTransactionAttributeSource

public AnnotationTransactionAttributeSource(Set<TransactionAnnotationParser> annotationParsers)

Create a custom AnnotationTransactionAttributeSource.

Parameters:

annotationParsers - the TransactionAnnotationParsers to use

Method Detail

findTransactionAttribute

@Nullable
protected TransactionAttribute findTransactionAttribute(Method method)

Description copied from class: AbstractFallbackTransactionAttributeSource

Subclasses need to implement this to return the transaction attribute for the given method, if any.

Specified by:

findTransactionAttribute in class AbstractFallbackTransactionAttributeSource

Parameters:

method - the method to retrieve the attribute for

Returns:

all transaction attribute associated with this method (or null if none)

findTransactionAttribute

@Nullable
protected TransactionAttribute findTransactionAttribute(Class<?> clazz)

Description copied from class: AbstractFallbackTransactionAttributeSource

Subclasses need to implement this to return the transaction attribute for the given class, if any.

Specified by:

findTransactionAttribute in class AbstractFallbackTransactionAttributeSource

Parameters:

clazz - the class to retrieve the attribute for

Returns:

all transaction attribute associated with this class (or null if none)

determineTransactionAttribute

@Nullable
protected TransactionAttribute determineTransactionAttribute(AnnotatedElement ae)

Determine the transaction attribute for the given method or class.

This implementation delegates to configured TransactionAnnotationParsers for parsing known annotations into Spring's metadata attribute class. Returns null if it's not transactional.

Can be overridden to support custom annotations that carry transaction metadata.

Parameters:

ae - the annotated method or class

Returns:

TransactionAttribute the configured transaction attribute, or null if none was found

allowPublicMethodsOnly

protected boolean allowPublicMethodsOnly()

By default, only public methods can be made transactional.

Overrides:

allowPublicMethodsOnly in class AbstractFallbackTransactionAttributeSource

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
