Spring data @Transactional not roll back

Question

I develops my first application using Spring MVC and Spring JPA. I get a problem when using @Transactional annotation. I annotate one of my service methods with @Transactional and I throw exception in that method because I expect it to be rolled back, but it do not.

here is my configuration files and my class files content:

In AttributeService.java, in save method, you can find:

t = attributeRepository.save(t);

if(t.getId() > 1){
            throw new Exception();
        }

So after I call save, I immediately throw an exception, but then I check the database and it did not rolled back.

I really appreciate any help from you guys, Thanks!

Answer 1

I found the problem. In app-context.xml and servlet-context.xml, both have <context:component-scan/>. That tag will cause the problem that explained in this link: Spring @Transactional annotations ignored.

Answer 2

your Attribute class do not have id field. is it coming from AbstractPersistable<Long> can you show how did you annoted the ID field? is it Auto generated?

Depending upon answs to above there may be sevral possible things. 1. your Id never becomes greater than 1 and excepion is never thrown

I will suggest to try with below code and let me know if even after it the transaction is not rolled back.

t = attributeRepository.save(t);
throw new Exception();

Also showing code on how id is mapped in your Attribute class will be helpful to help you

Also how and where you have called the AttributeService Save Method also affects the transactions. that part of code will be helpful too.
