The attribute readOnly is undefined for the annotation type Transactional

Question

I am getting this error when I am putting this piece of code on a service method

 @Transactional(readOnly =true)

I am writing this code to make a transaction read only. Can you please tell me What I did wrong in this case

Answer 1

Make sure you import @Transactional from org.springframework.transaction.annotation.Transactional and not from javax.transaction.Transactional as readOnly attribute is specific to Spring transaction.

Answer 2

Add

import org.springframework.transaction.annotation.Transactional;
