Example using @Transactional

In Spring Boot, the TransactionTemplate is not commonly used. Instead, the @Transactional annotation is typically utilized for transaction management. Let me provide an updated example using @Transactional.

javaCopy code
@Service
public class ExampleService {

    @Autowired
    private TransactionalService transactionalService;

    @Transactional
    public void performTwoTransactions() {
        try {
            // Perform transaction 1
            transactionalService.transaction1();

            // Perform transaction 2
            transactionalService.transaction2();
        } catch (Exception e) {
            // Handle exceptions or rethrow
        }
    }
}

In this example, the ExampleService class calls two transactional methods transaction1() and transaction2() from a separate TransactionalService class. Both methods are annotated with @Transactional. If an exception occurs in either method, the transactional aspect of Spring will automatically roll back both transactions.

javaCopy code
@Service
public class TransactionalService {

    @Autowired
    private UserRepository userRepository;

    @Transactional
    public void transaction1() {
        // Perform operations with userRepository
    }

    @Transactional
    public void transaction2() {
        // Perform operations with userRepository
    }
}

In the TransactionalService, the transaction1() and transaction2() methods are annotated with @Transactional. This annotation ensures that each method runs within its transactional context. If an exception occurs, Spring will handle the transaction rollback.

By utilizing the @Transactional annotation, you can simplify transaction management in Spring Boot and achieve the desired rollback behavior within a method.
