Impossibile trovare Spring NamespaceHandler per lo spazio dei nomi dello schema XML [http://www.springframework.org/schema/data/jpa]

Question

Qualche idea, che cosa potrebbe causare questo errore?

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: problema di configurazione: Impossibile individuare primavera NamespaceHandler per schema XML namespace [http://www.springframework.org/schema/data/jpa] risorsa Offending: risorsa ServletContext [/WEB-INF/spring/appServlet/servlet-context.xml]

ecco il mio 'servle-context.xml' (ci sono alcuni problemi con i rientri, ma il file è troppo grande ...):

Come puoi vedere, ho specificato il percorso dello schema jpa. E io non so qual è il problema

Answer 1

provare a sostituire

http://www.springframework.org/schema/data/jpa/spring-jpa.xsd

da

http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd

Ma se si utilizza ancora la versione 1.0-M1 quindi provare a primo aggiornamento . DATAJPA-21

Answer 2

Il problema è dovuto al fatto che lo schema spring-jpa non può essere localizzato. Potresti avere un vecchio jar che non contiene le informazioni sullo schema.

Answer 3

Ho risolto questo risolvendo la mancanza della dipendenza tx molla nel nostro progetto.

org.springframework: primavera-tx

Answer 4

So che questo sembra stupido, ma se si utilizza IDEA e Maven si dovrebbe controllare per essere sicuri di avere Usa registro plugin di controllare in modo che il server ha anche accesso al vostro file jar.

Vorrei pubblicare una schermata ma sono nuovo qui e non ho abbastanza punti reputazione. Esso funziona e anche se ho verificato con il team di supporto a IntelliJ

Answer 5

Assicurarsi di avere la primavera-dati-APP nelle dipendenze

Se si utilizza Maven:

<dependency> 
    <groupId>org.springframework.data</groupId> 
    <artifactId>spring-data-jpa</artifactId> 
    <version>1.7.0.RELEASE</version> 
</dependency> 

Answer 6

Dopo aver affrontato questo lo stesso problema in una settimana, ho trovato una soluzione. Se si utilizza Spring MVC + APP + Maven, utilizzare questo dispatcher-servlet.xml

<?xml version="1.0" encoding="windows-1252"?>

    <!-- Add JPA support -->

     </property> 
    </bean> 

    <!-- Add Transaction support -->

     <property name="suffix" value=".jsp"/> 
    </bean> 

</beans> 

Answer 7

troppo tardi, ma questo risolto il mio problema:

<dependency> 
    <groupId>org.springframework.data</groupId> 
    <artifactId>spring-data-jpa</artifactId> 
    <version>1.9.4.RELEASE</version> 
</dependency>
