春天的事务管理的JdbcTemplate

Question

I am running a java project using jdbctemplate in which update of 2000 records is happening with batch size of 500 records.

Since, i am using single update query would there improvement in application if i would use spring transaction management ?

Answer 1

As per my knowledge it would help in the performance as code is going to hit the database only once

even I would suggest to use

@Override
public <S extends Classname> Iterable<S> save(Iterable<S> arg0);

Which save the entities present in list directly to database without using either jdbcTemplate or transaction management

Answer 2

this is decided by your requirement. if 2000 records must constants,so you have to use transaction management,if not , you can deal one record every time.

Answer 3

It can definitely help you. You can make the 500 record batch calls one by one in a Java method annotated with @Transactional annotation. That way, spring will roll back the whole operation in the event that any of the update fails.

PS: I haven't specified any XML configurations where you have to specify your transaction manager. You can add a suitable one meeting your needs.
