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

Question

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

Answer 1

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) {     // ... } 

Answer 2

I have been getting similar error, and just want to share with you. maybe it will help someone.

If you want to use EntityManagerFactory to get an EntityManager, make sure that you will use:

<persistence-unit name="name" transaction-type="RESOURCE_LOCAL"> 

and not:

<persistence-unit name="name" transaction-type="JPA"> 

in persistance.xml

clean and rebuild project, it should help.
