Class a{ function a1(){ a2() } **@transactional** function a2(){ b.a3() } class b{ function a3(){ } } the answer is yes.by default @transactional has a propagation of required,so a3() will be in transaction.spring doc transaction propagation We will also create repository layer to perform operations on database using spring data jpa. Similarly the data transfer objects will help us take data from service layer and convert it to repository and vice versa.
This Tutorial Will Focus On Introducing Spring Data Jpa Into A Spring Project, And Fully Configuring The Persistence Layer.
Spring calls transactionmanager::gettransaction to get or create a transaction according to the propagation. It supports some of the propagations for all types of transactionmanager , but there are a few of them that are only supported by specific implementations of. We will also create repository layer to perform operations on database using spring data jpa.
Similarly The Data Transfer Objects Will Help Us Take Data From Service Layer And Convert It To Repository And Vice Versa.
Spring uses proxies and as such the @transactional in this case is pretty much useless. You can avoid that problem by annotating your observer method with @transactional(propagation = propagation.requires_new). And then spring is smart enough to transparently handle transactions for you:
This Tutorial Will Discuss The Right Way To Configure Transactions For Multiple Databases, How To Use @Transactional And Some Common Pitfalls.
The class simplejparepository itself is annotated with @transactional (readonly = true), that means by default all method will run within. This article will focus on the configuration of transactions with spring 3.1 and jpa. For a step by step introduction about.
