title: does Spring @transactional work with MongoDB?
body: <p>I'm developing a web application with Spring Boot and MongoDB. I want to make the services work with the @transactional spring annotation, but I don't know if that really works. (I didn't work with mongoDB before).</p>
  
  <p>I added the annotation and it seem that everything run fine (The application runs and I can do all operations CRUD), but, I don't know if Spring is ignoring the annotation and it is working as usual, or is really considering the transactionality.</p>
  
  <p>In other post, I have seen that I should add a new bean in the configuration class, in order to enable the transactionlity between Spring and MongoDB. Is it really necessary?, I only use transactions with single Mongo documents.</p>
