To commit multiple operations in a single transaction, you can use:

Transaction transaction=SessionFactory.getTransaction ()

Transaction.begin (); / / transaction starts

/ /. Put multiple operations here

Transaction.commit (); / / commit the transaction and end the transaction

Specific examples are as follows:

Public static void main (String [] args) {

Suid suid=BeeFactory.getHoneyFactory () .getSuid ()

SuidRich suidRich=BeeFactory.getHoneyFactory () .getSuidRich ()

Orders orders = new Orders ()

Orders.setUserid ("Test1008-1")

Orders.setTotal (new BigDecimal ("10.0")

Suid.insert (orders); / / single stroke operation, submitted by default

Orders orders2 = new Orders ()

Orders2.setUserid ("Test1008-2")

Orders2.setTotal (new BigDecimal ("0.0"))

Suid.insert (orders2)

Transaction transaction=SessionFactory.getTransaction ()

Transaction.begin (); / / transaction starts

Orders orders3=suidRich.selectOne (orders)

Orders3.setTotal (new BigDecimal ("5.0"))

Orders orders4=suidRich.selectOne (orders2)

Orders4.setTotal (new BigDecimal ("5.0"))

SuidRich.update (orders3)

SuidRich.update (orders4)

Transaction.commit (); / / commit the transaction and end the transaction

}
