Question 2

Explanation

To use transactions in Spring, the two required elements from the options you’ve provided are:

1. Annotate a class, an interface, or individual methods requiring a transaction with the @Transactional annotation.

2. Add @EnableTransactionManagement to a Java configuration class.

The @Transactional annotation is used to declare that a method, class, or interface should have transactional behavior. The @EnableTransactionManagement annotation enables Spring’s annotation-driven transaction management capability, similar to the support found in Spring’s <tx:*> XML namespace.

The other options are not correct:

• A class does not need to implement the TransactionInterceptor interface to require a transaction.

• Writing a Spring AOP advice is not a requirement as transactional behavior can be added declaratively with the @Transactional annotation.

• A class does not need to be annotated with both @Service and @Transaction. The @Service annotation is a stereotype for the service layer, and there is no @Transaction annotation in Spring. Transactional behavior is typically declared with @Transactional.
