What can be the consequences of using the @Lazy annotation without the corresponding @Transactional annotation in Spring?

Using the @Lazy annotation without the corresponding @Transactional annotation in Spring can lead to a lazily initialized bean being created outside of a transaction context. This means that database operations performed within this bean will not be wrapped in a transaction, which can result in data inconsistency or errors during query execution.

For example, if a service bean is marked as @Lazy but does not have @Transactional, then a transaction will not be automatically created on its first method call, and changes to the database may not be committed or may cause errors.

Therefore, it is recommended to use @Transactional together with @Lazy if the bean performs database operations that require transactional support.
