Digging into Spring's Source 17: @Transactional — Who Opens a Transaction and Who Closes It
Put @Transactional on a method and somebody opens a transaction, rolls it back on an exception and commits it otherwise — this post follows who that somebody is, in the real source. The three interfaces PlatformTransactionManager, TransactionDefinition and TransactionStatus, the beans that @EnableTransactionManagement registers, the order in which TransactionInterceptor wraps a call, where propagation branches, why the connection is bound to a ThreadLocal, and traps such as "checked exceptions do not roll back" and "the outer method gets an UnexpectedRollbackException when the inner one fails", all checked with examples.
