non è possibile trovare alcuna dichiarazione per l'elemento 'jpa: repository'

Question

Ho creato un progetto Spring semplice e vorrei configurare JPA in esso. Ho seguito questo tutorial: http://duckranger.com/2012/04/spring-mvc-3-x-with-sts-tutorial-part-iii-add-some-jpa/comment-page-1/#comment-3085

Ora sono giunto al termine, ma quando provo a fare funzionare la prova secondo il tutorial che sto ottenendo l'errore qui sotto:

Questa è la parte esatta che si lamenta:

Ecco come il mio applicationContext.xml assomiglia:

Chiunque potrebbe aiutare per favore? Molte grazie.

Answer 1

Per risolvere questo problema, è necessario ordinare correttamente la definizione in applicationContext.xml, posizionare "tx" e "tx-spring" dopo il "contesto molla", quindi l'errore verrà risolto.

Answer 2

Nell'intestazione dichiarazione XML includere le seguenti righe di avere schema primavera dati Repository dichiarato:

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     OTHER DEFINITIONS 
     xmlns:repository="http://www.springframework.org/schema/data/repository" 
     xsi:schemaLocation=" OTHERS 
     http://www.springframework.org/schema/data/repository 
     http://www.springframework.org/schema/data/repository/spring-repository.xsd"> 

</beans> 

Speranza che aiuta.
