org.springframework.beans.factory.BeanCreationException: Fout bij maken van bean met naam ‘MyController’:

Ik ben bezig met de lente + winterslaaptoepassing. Wanneer ik de applicatie op de Tomcat-server uitvoer, krijg ik enkele uitzonderingen.

Gekopieerd van de stacktrace:

BeanInstantiationException: kan bean-klasse niet instantiëren [com.gestEtu.project.model.dao.CompteDAOHib]: geen standaardconstructor gevonden; geneste uitzondering is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

Standaard zal Spring proberen om beans te instantiëren door een standaard (no-arg) constructor aan te roepen. Het probleem in jouw geval is dat de implementatie van de CompteDAOHibeen constructor heeft met een SessionFactory-argument. Door de annotatie @Autowiredtoe te voegen aan een constructor, zal Spring proberen een bean van het overeenkomende type te vinden, SessionFactoryin jouw geval, en dit als een constructorargument op te geven, bijvoorbeeld

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

Ik heb een soortgelijke foutmelding gekregen en wil deze graag met u delen. misschien helpt het iemand.

Als je EntityManagerFactorywilt gebruiken om een EntityManagerte krijgen, zorg er dan voor dat je het volgende gebruikt:

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

en niet:

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

in persistance.xml

project opschonen en opnieuw opbouwen, dat zou moeten helpen.

Uitzondering geeft duidelijk het probleem aan.

CompteDAOHib: No default constructor found

Voor de lente om je boon te instantiëren, moet je een lege constructor opgeven voor je klasse CompteDAOHib.

Antwoord 4, autoriteit 7%

Verander van @Controller naar @Service naar CompteController en
voeg @Service-annotatie toe aan CompteDAOHib.
Laat het me weten als je nog steeds met dit probleem wordt geconfronteerd.

Antwoord 5, autoriteit 7%

Als er niets gebeurt, zelfs als je alle benodigde annotaties hebt toegevoegd, probeer dan deze afhankelijkheid toe te voegen aan je pom.xml, ik had net hetzelfde probleem en heb het opgelost door deze hier toe te voegen:

p>

<dependency>
   <groupId>commons-configuration</groupId>
   <artifactId>commons-configuration</artifactId>
   <version>1.9</version>
</dependency>

org.springframework.beans.factory.BeanCreationException: fout bij het maken van bean met de naam ‘MyController’

Zorg ervoor dat u ojdbc14.jarheeft toegevoegd aan uw bibliotheek.

Gebruik voor oracle 11g ojdbc6.jar.

Antwoord 7

Ik gebruikte Spring op NetBeans IDE en had dat probleem ook, blijkbaar ben ik gewoon vergeten de MySQL JDBC Driver-bibliotheek toe te voegen en het lost mijn probleem op.
