Im working on developing a webapplication with Spring 3 and Hibernate 3.6. Ive got some questions to the
@Transactional Annotation and the structure of the code.
-> When I use
@Transactional (transaction management with Spring), do I have to surround the
@Transactional-annotated methods with try/catch when calling them?
For example, when I got a method which loads, changes and returns then an object and I call it from another class: do I have to surround the call with try/catch? maybe something goes wrong, no object is returned, database connection fails.. I dont know.
until now, I thought
@Transactional cares for all possible occurring exceptions and rolls back every operation in this transaction when an error occurs.
but if it occurs, I must inform the user somehow. when I call the transactional-method in the try-block and it is rolled back, the catch block is activated?
I can tell then the user "something did go wrong". Otherwise the user maybe would not be informed?
Or is it sufficient to check if there is an object returned (if/else), then I dont need try/catch?
Im new and I would like to hear how other structure their code. Thank you 🙂
