Method Details

isCandidateClass

public boolean isCandidateClass(Class<?> targetClass)

Description copied from interface: TransactionAnnotationParser

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

If this method returns false, the methods on the given class will not get traversed for #parseTransactionAnnotation 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 TransactionAnnotationParser

Parameters:

targetClass - the class to introspect

Returns:

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

parseTransactionAnnotation

@Nullable
public TransactionAttribute parseTransactionAnnotation(AnnotatedElement element)

Description copied from interface: TransactionAnnotationParser

Parse the transaction attribute for the given method or class, based on an annotation type understood by this parser.

This essentially parses a known transaction annotation into Spring's metadata attribute class. Returns null if the method/class is not transactional.

Specified by:

parseTransactionAnnotation in interface TransactionAnnotationParser

Parameters:

element - the annotated method or class

Returns:

the configured transaction attribute, or null if none found
