public class TransactionAttributeSourceTransactionAroundAdvisor

extends StaticMethodMatcherPointcutAdvisor

implements Ordered

InterceptionAroundAdvisor driven by a TransactionAttributeSource. Used to exclude TransactionInterceptor from methods that are non transactional. Because the AOP framework caches advice calculations, this is normally faster than just letting the TransactionInterceptor run and find out itself that it has no work to do.

Field Detail

ORDER_VALUE

public static final int ORDER_VALUE

Most advice will want to run within a transaction context, so we set the order value to be quite high. Other advisors can use a higher value than this if want to ensure that they always run within a transaction context.
Order value applies only when ordering is not specified in configuration: for example, it applies when using an AdvisorAutoProxyCreator.

Method Detail

matches

public boolean matches(java.lang.reflect.Method m,
                       java.lang.Class targetClass)

Description copied from interface: MethodMatcher

Perform static checking. If this returns false, or if the isRuntime() method returns false, no runtime check will be made.

Specified by:

matches in interface MethodMatcher

Parameters:

m - candidate method

targetClass - target class (may be null, in which case the candidate class must be taken to be the method's declaring class)

Returns:

whether or not this method matches statically

See Also:

MethodMatcher.matches(java.lang.reflect.Method, java.lang.Class)

getOrder

public int getOrder()

Description copied from interface: Ordered

Return the order value of this object, higher value meaning greater in terms of sorting. Normally starting with 0 or 1, Integer.MAX_VALUE indicating greatest. Same order values will result in arbitrary positions for the affected objects.

Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Specified by:

getOrder in interface Ordered

Returns:

the order value
