  1. POspring and @transactional, is this normal?
    text
    copied!<p>i wrote this simple example:</p> <pre><code>//file TestController.java public interface TestController { public List&lt;Test&gt; findAll(); } //file TestControllerImp.java @Controller public class TestControllerImp implements TestController{ @Autowired private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory=sessionFactory; } public List&lt;Test&gt; findAll() { return sessionFactory.getCurrentSession().createQuery("from Test").list(); } } //file TestService.java @Service public class TestService { @Autowired private TestController controller; public boolean flag=true; public void setController(TestController controller){ this.controller=controller; } @Transactional public List&lt;Test&gt; useController(){ flag=false; return controller.findAll(); } } </code></pre> <p>And this is my try:</p> <pre><code>TestService s1=context.getBean(TestService.class); TestService s2=context.getBean(TestService.class); List&lt;Test&gt; list=s1.useController(); System.out.println(s1.flag+" "+s2.flag); </code></pre> <p>Now the strange behaviour (im very new with spring):</p> <ol> <li>If i declare <code>@Transactional</code> the method "useController()", the output is: true true</li> <li>If i move <code>@Transactional</code> from <code>TestService</code> to <code>TestControllerImp</code>, and i declare "findAll()" with <code>@Transactional</code>, the output is: false false.</li> </ol> <p>Why i have this behaviour? I know by default <code>@Autowired</code> classes are singletone, but why in the first case the flag still remains true?</p> <p>Thanks all.</p>
