Spring claims-based transaction management approach

Annotation-based transaction management It makes it easy to manage transactions but you still need to use the @transactional annotation tag for all the implementation classes of the business layer, so is there a simpler way to manage transactions with barely?

Claims-based transaction management requires only a small amount of configuration to add transaction management for all business layer logic, removing Userserviceimpl.java @ on a springmvc+hibernate4+bootstrap3 basis transactional annotations and modify the Applicationcontext.xml as follows:

Tx:advice is used to define an enhancement, where the enhancement is transaction management, Aop:pointcut is used to define the tangency point, and the aop:advisor tag adds transaction management enhancements to the specified tangency point for the purpose of enhancing the pointcut.
