Interface TransactionAnnotationParser

All Known Implementing Classes:
Ejb3TransactionAnnotationParser, JtaTransactionAnnotationParser, SpringTransactionAnnotationParser

public interface TransactionAnnotationParser
Strategy interface for parsing known transaction annotation types. AnnotationTransactionAttributeSource delegates to such parsers for supporting specific annotation types such as Spring's own Transactional, JTA 1.2's Transactional or EJB3's TransactionAttribute.

  • Method Summary

    Modifier and Type
    Method
    Description
    default boolean
    isCandidateClass(Class<?> targetClass)
    Determine whether the given class is a candidate for transaction attributes in the annotation format of this TransactionAnnotationParser.
    Parse the transaction attribute for the given method or class, based on an annotation type understood by this parser.
  • Method Details

    • isCandidateClass

      default boolean isCandidateClass(Class<?> targetClass)
      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.

      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 TransactionAttribute parseTransactionAnnotation(AnnotatedElement element)
      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.

      Parameters:
      element - the annotated method or class
      Returns:
      the configured transaction attribute, or null if none found
