Java: Transactions and Proxies

@Transactional manages transactions automatically, reducing boilerplate code.

In Spring, using @Transactional simplifies transaction management by automatically handling commit and rollback operations. This reduces the need to manually manage transactions in your code. For example, in an e-commerce app, marking a checkout method as @Transactional ensures that all database updates happen in a single transaction, preventing issues like partial updates if an error occurs.
