Impossibile creare una configurazione, poiché non è stato possibile trovare alcun provider di convalida di bean. Aggiungere un provider come Hibernate Validator (RI) per classpath

Question

Oggi, Sto cercando di inviare e-mail, ma quando aggiungo

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-context-support</artifactId> 
    <version>4.2.5.RELEASE</version> 
</dependency> 

<dependency> 
    <groupId>javax</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>7.0</version> 
</dependency> 

<dependency> 
    <groupId>javax.mail</groupId> 
    <artifactId>javax.mail-api</artifactId> 
    <version>1.5.5</version> 
</dependency> 

a pom.xml e distribuire sul server, ottengo un "Impossibile creare una configurazione, poiché non è stato possibile trovare alcun provider di convalida Bean. Aggiungere un provider come Hibernate Validator (RI) al classpath. " eccezione di validazione.

Ho appena aggiunto la dipendenza sopra e quella per la posta elettronica a un progetto MVC modello.

Answer 1

Aggiungi un Bean Validation provider di dipendenza per esempio Hibernate Validator. La dipendenza dell'API di convalida del bean è disponibile sul classpath ma manca l'implementazione. Aggiungere la seguente al pom.xml

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-validator</artifactId> 
    <version>5.2.4.Final</version> 
</dependency> 

Answer 2

È necessario aggiungere qualsiasi dipendenza fornitore di convalida per esempio Hibernate Validator.

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-validator</artifactId> 
    <version>5.2.1.Final</version> 
</dependency> 
<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-validator-annotation-processor</artifactId> 
    <version>5.2.1.Final</version> 
</dependency>
