I have two insert operation in one http post request. something like
@Service
public class StudentService {
@Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRED)
public int create(final Student student) {
// insert into table 1
// insert into table 2 using id return from insert 1, but something BAD happen here
}
}
so, I added @Transactional at method level as shown above.
In order to make it work, I added this tx:annotation-driven
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
so my app-servlet.xml looks like
<?xml version="1.0" encoding="UTF-8"?>
<beans

</bean>
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
</beans>
the component-scan will basically scan all class include controller, service, model, viewmodel, helper class etc.
If I remove the tx:annotation-driven, the @transactional won't work.
But once I add this tx:annotation-driven, some error starts to appear, like
Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.app.service.StudentService com.app.controller.HomeController.studentRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'studentService' defined in file [/path/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/MathSchool/WEB-INF/classes/com/app/service/StudentService.class]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/cglib/transform/impl/MemorySafeUndeclaredThrowableStrategy
How can I make this @transactional work.
