[英]Hibernate: The dialect was not set. Set the property hibernate.dialect
我有以下hibernate.cfg.xml
:
<hibernate-configuration>
<session-factory>
<property name="hibernate.format_sql">true</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/EJB</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">password</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>
<!-- Snip -->
我用這條線消耗的:
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
然后,在其他地方我試試這個:
SimpleSelect pkSelect = new SimpleSelect(Dialect.getDialect());
這導致以下異常:
org.hibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect.
注意,以下日志摘錄:
02:26:48,714 INFO Configuration:1426 - configuring from resource: /hibernate.cfg.xml
02:26:48,717 INFO Configuration:1403 - Configuration resource: /hibernate.cfg.xml
02:26:48,909 DEBUG Configuration:1387 - hibernate.dialect=org.hibernate.dialect.MySQLDialect
我有什么想法我做錯了嗎?
getDialect()
的javadoc說:
獲取當前系統屬性指定的方言實例。
因此,您必須在hibernate.dialect
配置hibernate.properties
才能使此方法正常工作。
使用SessionFactoryImplementor#getDialect()
。
