database - 如何避免 'Could not determine Hibernate dialect for database name [H2]!' ？

Question

我在运行 grails run-app 时收到此错误:

Error executing bootstraps: Error creating bean with name 'messageSource': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Cannot resolve reference to bean 'hibernateProperties' while setting bean property 'hibernateProperties'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateProperties': Cannot resolve reference to bean 'dialectDetector' while setting bean property 'properties' with key [hibernate.dialect]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dialectDetector': Invocation of init method failed; nested exception is org.codehaus.groovy.grails.orm.hibernate.exceptions.CouldNotDetermineHibernateDialectException: Could not determine Hibernate dialect for database name [H2]!

相应的DataSource.groovy:

dataSource {
  pooled = true
  driverClassName = "org.h2.Driver"
  username = "sa"
  password = ""
  // Adding this causes a different error:
  // dialect = org.hibernate.dialect.H2Dialect
}

hibernate {
  cache.use_second_level_cache = true
  cache.use_query_cache = true
  cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider'
}

environments {
  development {
    dataSource {
      dbCreate = "create-drop" // one of 'create', 'create-drop','update'
      url = "jdbc:h2:mem:devDB"
    }
  }
  test { // test-related stuff }
  production { // prod-related stuff }
}

当我明确提供上述方言 (org.hibernate.dialect.H2Dialect) 时，会发生此错误:

执行 Bootstrap 时出错:创建名称为“messageSource”的 bean 时出错:bean 初始化失败；嵌套异常是org.springframework.beans.factory.BeanCreationException:创建名称为“transactionManager”的bean时出错:设置bean属性“sessionFactory”时无法解析对bean“sessionFactory”的引用；嵌套异常是org.springframework.beans.factory.BeanCreationException:创建名称为“sessionFactory”的bean时出错:调用init方法失败；嵌套异常是java.lang.InknownClassChangeError:找到类org.hibernate.cfg.Mappings，但需要接口(interface)

有人知道如何处理这个问题吗？

这是 Joda Time 插件中的一个错误。请参阅提到的JIRA issue了解详情。
