java - @Transactional in the controller -

first of want mention agree make service layer transactional, world not perfect, , right i´m in middle of situation. have been assigned wonderful project legacy code of 4+ years. thing developers did not follow pattern introduce bussines logic can image multiples services call controller , after call private method controller. no budget refactor, , have many issues acid solution found make controllers transactional , @ least have full rollback if in middle of request/response go wrong. problem cannot make works. describe configuration see if can me out guys. have dispatcherservlet invoke webmvc-config.xml have declaration of controllers

     <context:component-scan base-package="com.greenvalley.etendering.web.controller**" use-default-filters="false">          <context:include-filter expression="org.springframework.stereotype.controller" type="annotation"/>     </context:component-scan> 

then contextconfiguration invoke applicationcontext.xml have rest of spring configuration.

after read many tickets tried many convination, example try declare again controllers application context.

  <tx:annotation-driven mode="aspectj"/> tried proxy  <context:component-scan base-package="com.greenvalley.etendering.web.controller.*" /> 

but still nothing.

in configuration of txmanager dont nothing fancy, add reference entitymanagerfactory , that´s it

<tx:annotation-driven transaction-manager="transactionmanager"/>  <bean id="transactionmanager" class="org.springframework.orm.jpa.jpatransactionmanager">     <property name="entitymanagerfactory" ref="entitymanagerfactory"/> </bean> 

in controller add @transactional, nothing every time made request @transactional class/method dont see breakpoint jpatransactionalmanager dobegin method stop

any suggestion please!
