org.springframework.beans.factory.BeanCreationException: Error al crear bean con el nombre ''MyController'':

Question

Estoy haciendo la aplicación de primavera + hibernación. Cuando ejecuto la aplicación en el servidor tomcat obtengo algunas excepciones.

Answer 1

org.springframework.beans.factory.BeanCreationException: Error al crear bean con el nombre ''MyController''

Asegúrese de haber agregado ojdbc14.jar en su biblioteca.

Aquí estoy usando oracle11g , para el cual no hay ojdbc14.jar . ¿Que puedo hacer?

Answer 2

Cambie de @Controller a @Service a CompteController y agregue la anotación @Service a CompteDAOHib. Déjame saber si todavía te enfrentas a este problema.

Answer 3

Copiado del stacktrace:

BeanInstantiationException: no se pudo crear una instancia de la clase de bean [com.gestEtu.project.model.dao.CompteDAOHib]: no se encontró un constructor predeterminado; la excepción anidada es java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib. <init> ()

De forma predeterminada, Spring intentará crear una instancia de los beans llamando a un constructor predeterminado (no-arg). El problema en su caso es que la implementación de CompteDAOHib tiene un constructor con un argumento SessionFactory . Al agregar la anotación @Autowired a un constructor, Spring intentará encontrar un bean de tipo coincidente, SessionFactory en su caso, y lo proporcionará como un argumento de constructor, por ejemplo

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

Answer 4

He estado recibiendo un error similar, y solo quiero compartir con ustedes. tal vez ayude a alguien

Si desea usar EntityManagerFactory para obtener un EntityManager , asegúrese de usar:

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

y no:

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

en persistance.xml

proyecto de limpieza y reconstrucción, debería ayudar.

Answer 5

La excepción indica claramente el problema.

CompteDAOHib: No default constructor found

Para que Spring pueda crear una instancia de su bean, debe proporcionar un constructor vacío para su clase CompteDAOHib .
