org.hibernate.HibernateException: Zugriff auf DialectResolutionInfo kann nicht null sein, wenn 'Hibernate.dialect'

Question

Ich weiß, das ist eine häufig gestellte Frage, aber keine der verfügbaren Lösungen funktionieren für mich. Unten ist mein booltstraps.xml:

wenn ich <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> ausdrücklich auf die Hibernate-Eigenschaften hinzufügen es anfängt zu arbeiten.

Die häufigste Antwort, die online verfügbar ist, besteht darin, dass bei der Verbindung mit der DB ein Problem auftritt. Also habe ich versucht, ein separates Stück Code zu schreiben, um mit den gleichen Details auf die DB zuzugreifen, und es hat funktioniert. Weiß nicht, was das Problem ist.

Answer 1

In der XML-Spring-Konfiguration, müssen Sie aktualisieren:

<bean class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" id="sessionFactory" lazy-init="true"> 
     <property name="dataSource" ref="dataSource"/> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.cache.use_second_level_cache">false</prop> 
       <prop key="hibernate.cache.use_query_cache">false</prop> 
       <prop key="hibernate.show_sql">false</prop> 
       <!-- HERE THE DIALECT CONFIGURATION --> 
      </props> 
     </property> 

    </bean> 

Von Hibernate documentation Sie den Dialekt, wie folgend müssen:

• Ein Dialekt für Microsoft SQL Server 2008 mit JDBC-Treiber 3.0 und oben

<prop key="hibernate.dialect">org.hibernate.dialect.SQLServer2008Dialect</prop>

• Ein Dialekt für Microsoft SQL Server 2000 und 2005

<prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
