Class AbstractFallbackTransactionAttributeSource
- All Implemented Interfaces:
Aware
,EmbeddedValueResolverAware
,TransactionAttributeSource
- Direct Known Subclasses:
AnnotationTransactionAttributeSource
TransactionAttributeSource
that caches
attributes for methods and implements a fallback policy: 1. specific target
method; 2. target class; 3. declaring method; 4. declaring class/interface.
Defaults to using the target class's transaction attribute if none is associated with the target method. Any transaction attribute associated with the target method completely overrides a class transaction attribute. If none found on the target class, the interface that the invoked method has been called through (in case of a JDK proxy) will be checked.

setEmbeddedValueResolver
Description copied from interface:EmbeddedValueResolverAware
Set the StringValueResolver to use for resolving embedded definition values.- Specified by:
setEmbeddedValueResolver
in interfaceEmbeddedValueResolverAware
-
getTransactionAttribute
@Nullable public TransactionAttribute getTransactionAttribute(Method method, @Nullable Class<?> targetClass) Determine the transaction attribute for this method invocation.Defaults to the class's transaction attribute if no method attribute is found.
- Specified by:
getTransactionAttribute
in interfaceTransactionAttributeSource
- Parameters:
method
- the method for the current invocation (nevernull
)targetClass
- the target class for this invocation (can benull
)- Returns:
- a TransactionAttribute for this method, or
null
if the method is not transactional
-
getCacheKey
Determine a cache key for the given method and target class.Must not produce same key for overloaded methods. Must produce same key for different instances of the same method.
- Parameters:
method
- the method (nevernull
)targetClass
- the target class (may benull
)- Returns:
- the cache key (never
null
)
-
computeTransactionAttribute
@Nullable protected TransactionAttribute computeTransactionAttribute(Method method, @Nullable Class<?> targetClass) Same signature asgetTransactionAttribute(java.lang.reflect.Method, java.lang.Class<?>)
, but doesn't cache the result.getTransactionAttribute(java.lang.reflect.Method, java.lang.Class<?>)
is effectively a caching decorator for this method.As of 4.1.8, this method can be overridden.
