Spring 3.1 entityManagerFactory java.lang.NoSuchFieldError: NULL Errore

Question

Ho appena migrato da Spring 3.0.5 a 3.1 GA. Ho riscontrato errori di runtime durante l'inizializzazione:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/spring/infrastructure-config.xml]: Initialization of bean failed; nested exception is java.lang.NoSuchFieldError: NULL

Ecco il mio xml.

<bean id="entityManagerFactory" 
    class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> 
    <property name="persistenceUnitName" value="MyPersistenceUnit" /> 
    </bean> 

A cosa serve questo java.lang.NoSuchFieldError: NULL? Nessun problema con 3.0.5.

Answer 1

Ciò significa che c'è una mancata corrispondenza della versione, molto probabilmente con le classi primaverili. Quindi assicurati che tutti i tuoi vasi primaverili siano 3.1.0. Soprattutto spring-expression. (Aggiorna anche il tuo provider JPA (ibernazione?) Se non funziona dopo il fissaggio della molla)

Answer 2

Potrebbe aiutarti. Upgrading from Spring 3.0.3.RELEASE results in: java.lang.NoSuchFieldError: USER_DECLARED_METHODS

prima avevo come questo

<dependencies> 
<!-- Spring 3 dependencies --> 
<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-core</artifactId> 
    <version>3.1.2.RELEASE</version> 
</dependency> 
... 
</dependencies> 

Poi ho aggiunto

<dependencies> 
<!-- Spring 3 dependencies --> 
<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-core</artifactId> 
    <version>3.1.2.RELEASE</version> 
    <exclusions> 
     <exclusion> 
      <groupId>org.springframework</groupId> 
      <artifactId>spring-core</artifactId> 
     </exclusion> 
    </exclusions> 
</dependency> 
... 

</dependencies>
