 org.springframework.transaction.interceptor.AbstractFallbackTransactionAttributeSource
All known Subclasses: org.springframework.transaction.interceptor.AttributesTransactionAttributeSource, org.springframework.transaction.annotation.AnnotationTransactionAttributeSource,
| AbstractFallbackTransactionAttributeSource | | abstract public class AbstractFallbackTransactionAttributeSource implements TransactionAttributeSource(Code) | | Abstract implementation of
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.
This implementation caches attributes by method after they are first used.
If it is ever desirable to allow dynamic changing of transaction attributes
(which is very unlikely), caching could be made configurable. Caching is
desirable because of the cost of evaluating rollback rules.

| Field Summary | |
| final Map | attributeCache
Cache of TransactionAttributes, keyed by DefaultCacheKey (Method + target Class). | | final protected Log | logger
Logger available to subclasses. |
| attributeCache | | final Map attributeCache(Code) | | Cache of TransactionAttributes, keyed by DefaultCacheKey (Method + target Class).
As this base class is not marked Serializable, the cache will be recreated
after serialization - provided that the concrete subclass is Serializable.
|
| logger | | final protected Log logger(Code) | | Logger available to subclasses.
As this base class is not marked Serializable, the logger will be recreated
after serialization - provided that the concrete subclass is Serializable.
|
| allowPublicMethodsOnly | | protected boolean allowPublicMethodsOnly()(Code) | | Should only public methods be allowed to have transactional semantics?
The default implementation returns false.
|
| findTransactionAttribute | | abstract protected TransactionAttribute findTransactionAttribute(Method method)(Code) | | Subclasses need to implement this to return the transaction attribute
for the given method, if any.
Parameters:
method - the method to retrieve the attribute for all transaction attribute associated with this method(or null if none) |
| findTransactionAttribute | | abstract protected TransactionAttribute findTransactionAttribute(Class clazz)(Code) | | Subclasses need to implement this to return the transaction attribute
for the given class, if any.
Parameters:
clazz - the class to retrieve the attribute for all transaction attribute associated with this class(or null if none) |
| getCacheKey | | protected Object getCacheKey(Method method, Class targetClass)(Code) | | 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 (never null)
Parameters:
targetClass - the target class (may be null) the cache key (never null) |
| getTransactionAttribute | | public TransactionAttribute getTransactionAttribute(Method method, Class targetClass)(Code) | | Determine the transaction attribute for this method invocation.
Defaults to the class's transaction attribute if no method attribute is found.
Parameters:
method - the method for the current invocation (never null)
Parameters:
targetClass - the target class for this invocation (may be null) TransactionAttribute for this method, or null if the methodis not transactional |
