Spring Transaction Propagations examples

How is it used in example

• PersonService.java has different methods defined with propagations levels as NEVER, NOT_SUPPORTED, SUPPORTED, MANDATORY, REQUIRED, REQUIRES_NEW and NESTED.
• PersonService.java has one non-transactional method 'callTransactionalMethodsWithoutTrasaction()' calling all propagation methods to test the behavior when transaction is not present.
• PersonService.java has one transactional method 'callTransactionalMethodsWithTrasaction()' calling all propagation methods to test behavior when transaction is present.
