MyBatis in sqlsession operation database, no error but unable to implement data modification (increase, change, delete)

public void Addcustomertest () throws Exception {        sqlsession sqlsession = mybatisutils.getsession ();        Customermapper customermapper = Sqlsession.getmapper (customermapper.class);        Customer customer = new Customer ();        Customer.setusername ("111");        Customer.setjobs ("111");        Customer.setphone ("111");        Customermapper.addcustomer (customer);        sqlsession.commit ();        Sqlsession.close ();    }

Database query operations can be implemented, but modifications cannot be implemented, and do not error, one of the reasons for this situation:

Transaction forgot to submit!

Add code sqlsession.commit ();

Long snacks can make fewer mistakes.
