What are the main reasons that can lead to transaction rollback in Spring Framework?

Main reasons for rollback of a transaction in Spring Framework:

• RuntimeExceptions or Errors by default lead to rollback.
• Explicit rollback calls via TransactionStatus.
• Conflicts with database locks or errors during data saving.
• Violation of data integrity constraints (e.g., uniqueness).

It is important to remember that checked exceptions by default do not cause rollback unless configured otherwise through the @Transactional annotation attributes.
