REQUIRED

• Support a current transaction, create a new one if none exists.
• Analogous to EJB transaction attribute of the same name.
• This is the default setting of a transaction annotation.

SUPPORTS

• Support a current transaction, execute non-transactionally if none exists.
• Analogous to EJB transaction attribute of the same name.
• Note: For transaction managers with transaction synchronization,
• {@code SUPPORTS} is slightly different from no transaction at all,
• as it defines a transaction scope that synchronization will apply for.
• As a consequence, the same resources (JDBC Connection, Hibernate Session, etc)
• will be shared for the entire specified scope. Note that this depends on
• the actual synchronization configuration of the transaction manager.

MANDATORY

• Support a current transaction, throw an exception if none exists.
• Analogous to EJB transaction attribute of the same name.
