description of how a transaction policy applies to a method. This description includes some of the following parameters: propagation behavior, isolation level, read-only prompt, transaction timeout interval. (1) Propagation behavior propagation behavior defines the transaction boundary of the client and the invoked method. Spring defines 7 distinct propagation behaviors. (A detailed list of 165 pages in the book) spring's propagation behavior corresponds to all propagation rules in the EJB cont
managers that the application needs to relate to. Spring itself does not support distributed transactions, so distributed transactions require low-level JTA. But spring provides an abstraction of the transaction, where the underlying true transaction implementation can switch without affecting the application code. This allows applications to rely on the underlying was, or easily, from the environment in which the application server is opened. This is very similar to the abstraction of the prev
recommended that you use the Hibernate Transaction API to hide the underlying transaction implementation from your code. If you execute in the EJB container that supports CMT, the transaction boundary is declared, and you do not need to perform any transaction or session management operations in your code. See chapter 11th Transactions and concurrency to read more content and sample code. The Hibernate.current_session_context_class configuration para

Think about it, Hibernate transaction is obtained from the session, Tx = session. begintransaction (), submit TX first, and then session. close, which fully complies with the Operation Sequence of the JDBC transaction, but this sequence is totally different from the transactioin Operation Sequence of JTA !!! JTA starts transaction first, then starts the session, closes the session, and finally submits the transaction. Therefore, when you use the transaction of JTA, never use the trans
