@groovy.transform.CompileStatic @org.codehaus.groovy.transform.GroovyASTTransformation(phase = CompilePhase.CANONICALIZATION) class TransactionalTransform extends AbstractDatastoreMethodDecoratingTransformation
This AST transform reads the Transactional annotation and transforms method calls by wrapping the body of the method in an execution of GrailsTransactionTemplate.
In other words given the following class:
class FooService {
@Transactional
void updateFoo() {
...
}
}
The resulting byte code produced will be (more or less):
class FooService {
PlatformTransactionManager $transactionManager
PlatformTransactionManager getTransactionManager() { $transactionManager }
void updateFoo() {
GrailsTransactionTemplate template = new GrailsTransactionTemplate(getTransactionManager())
template.execute { TransactionStatus status ->
$tt_updateFoo(status)
}
}
private void $tt_updateFoo(TransactionStatus status) {
...
}
}
The body of the method is moved to a new method prefixed with "$tt_" and which receives the arguments of the method and the TransactionStatus object
