Spring 3.0: "Le préfixe" X "pour l'attribut" Y "associé à un élément de type" Z "n'est pas lié"

Question

Mon application fonctionnait bien jusqu'à ce matin mais j'ai commencé à recevoir les erreurs ci-dessous après avoir renommé mon Netbeans 6.9 projet ce matin.

Je reçois l'erreur suivante lors de la construction de mon Spring 3.0.4 app:

The prefix "p" for attribute "p:driverClassName" associated with an element type "beans:bean" is not bound 

applicationContext.xml:

Le erreur ci-dessus provoque cette erreur:

Voir quelque chose de mal ici?

Answer 1

Je n'ai aucune expérience avec Netbeans, mais je suppose que le problème peut être lié au schéma XML pour l'espace de noms p.

C'est une supposition sauvage, mais laissez-moi le prendre. Peut-être avez-vous configuré Netbeans pour ajouter un XSD personnalisé à son catalogue et pointé vers le fichier XSD dans votre projet. Après avoir renommé le projet, le chemin d'accès au schéma XML de l'espace de noms p n'est pas valide.

Je ne sais même pas si une telle configuration de catalogue XML est possible dans Netbeans, je suis plutôt dans Eclipse. Mais je vérifierais cela à votre place.

Answer 2

Je sais que je suis en retard mais je suis même erreur et peut-être est-ce utile pour les autres .. je mets le

p:something 

dans

<property name="something" value="anything_you_want_to_set"/> 

Ainsi, au lieu de

p:driverClassName="net.sourceforge.jtds.jdbc.Driver" 

essayez ceci:

<bean> 
    <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver" /> 
    <!-- and your others property --> 
</bean> 

Answer 3

Vous devez ajouter des espaces de noms à votre déclaration de beans.

xmlns:c="http://www.springframework.org/schema/c" xmlns:p="http://www.springframework.org/schema/p"
