org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyController':

I am doing spring + hibernate application. When I run the application on tomcat server I am getting some exceptions.

Can anybody help to resolve this?

Answer

Copied from the stacktrace:

BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib has a constructor with a SessionFactory argument. By adding the @Autowired annotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactory in your case, and provide it as a constructor argument, e.g.

@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
    // ...
}
