title: Transactional: controller vs service
body: <p>Consider I have a controller method <code>get()</code> which calls a few service methods working with database.</p>
  
  <p>Is it correct to make the entire controller method transactional or just every service method?</p>
  
  <p>It seems to me that we must make <code>get()</code> transactional because it performs associated operations.</p>
