In my Spring application, I have a class annotated with org.springframework.transaction.annotation.Transactional annotation.
Is it possible to discard transactions for a specific single method of this class without removing @Transactional from class level declarations? If so, please show an example

Annotation Type Transactional. Describes a transaction attribute on an individual method or on a class. When this annotation is declared at the class level, it applies as a default to all methods of the declaring class and its subclasses.
When using proxies, you should apply the @Transactional annotation only to methods with public visibility. If you do annotate protected, private or package-visible methods with the @Transactional annotation, no error is raised, but the annotated method does not exhibit the configured transactional settings.
2.2. How to Use @Transactional. We can put the annotation on definitions of interfaces, classes, or directly on methods. They override each other according to the priority order; from lowest to highest we have: interface, superclass, class, interface method, superclass method, and class method.
According to Transactional documentation:
public @interface Transactional
Describes a transaction attribute on an individual method or on a class.
So additionally to the class-level annotation just define the correct attribute at your method to disable the default transaction handling.
example:
@Transactional(propagation=Propagation.NEVER)
public long notInTransaction(AnythingData anythingData) throws Exception {
//JDBC code...
}
Will throw an exception if this method is called inside an active transaction. Whereas Propagation.NOT_SUPPORTED will "suspend" the current transaction and make sure that the method is called non transactional.
