# spring

BTW as far as a understand, spring generates a proxy, and catches exceptions coming from methods/classes annotated with @Transaction to _commit_/_rollback_ the current transaction. However, I want my service layer to be something like Either<Error, A>

[thanksforallthefish]

my suggestion would be to write a wrapper around normally annotated @Transactional level to catch transaction exception and convert them into the A part of your Either (you can do Either<Result, RollbackTransactionException> - metacode)

spring is a java framework, a lot is done with exception and I don't like it either but you lose lot of power trying to be too smart

Yes, I don't like throwing an exception just because it's not in the database, but that's how it works..
