What are the transaction types in spring?

What is a transaction in spring boot?

What is transaction in the context of Spring Data?

Is @transactional mandatory?

REQUIRED is the default setting of a @Transactional annotation. Each method annotated with REQUIRED demarcates a logical transaction and these logical transactions participate in the same physical transaction.

Is @transactional necessary?

@Transactional should be used on specific methods where it is actually needed, not on the entire class. This makes it easier to see which methods are meant to be executed as one transaction, and which ones are not. You don’t need @Transactional for database operations that only read from the database.

Does @transactional rollback?

But be careful: Only unchecked exceptions (that is, subclasses of java. lang. RuntimeException) are rollbacked by default.

Is a transactional process?

A transactional process (in contrast to physical manufacturing) is one that transforms information and data. For example office activities, financial functions, credit card transactions, insurance industry, order processing, invoicing, and many service functions such as help lines and help desks.
