Spring "Il prefisso" tx "per l'elemento" tx: annotation-driven "non è associato."

Question

Viene visualizzato l'errore precedente sulla riga "tx: annotation-driven", ma ho dichiarato lo spazio dei nomi nella parte superiore del file bean, perché il seguente XML causa questo errore?

Answer 1

Proprio come gli altri xmlns: definations, avete bisogno di uno per xmlns: TX

xmlns:tx="http://www.springframework.org/schema/tx" 

Answer 2

Si può guardare here per ulteriori informazioni:

L'accordo tag TX con la configurazione di tutti i di questi fagioli nel supporto completo di Spring per le transazioni. Questi tag sono trattati nel capitolo dal titolo Capitolo 9, Gestione delle transazioni.

...

Per motivi di completezza, per utilizzare i tag nello schema tx, si bisogno di avere il seguente preambolo nella parte superiore del vostro XML Primavera file di configurazione ; il testo rafforzato nel seguente snippet fa riferimento allo schema corretto in modo che i tag nello spazio dei nomi tx siano disponibili per .

<?xml version="1.0" encoding="UTF-8"?>

     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd"> 

    <!-- <bean> definitions goes here --> 

</beans> 

Answer 3

È necessario introdurre l'annotazione tx al progetto, è necessario installarli, non uso il xmlns, non funziona correcty, vedo che si sviluppa con l'annotazione, la sua buona pratica e di utilizzare questo ,

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx.xsd
