Grails 3.0.1和Hibernate Session错误

Question

我正在关注基于Grails 2的书籍示例(Grails in Action 2nd Edition),但我使用的是新的Grails 3.0.1.

当我创建一个看起来像这样的域类:

package qotd

class Quote {
   String content
   String author
   Date created = new Date()
}

每当我尝试通过groovy控制台与DB交互时,我都会抛出异常.

org.springframework.dao.DataAccessResourceFailureException: Could not obtain current Hibernate Session;
Caused by: org.hibernate.HibernateException: No Session found for current thread

我试图将@Transactional添加到域类中,并且还切换到较低的JDK版本(7),但它们都不起作用.我也用Grails 3.0测试过,结果是一样的.如果我降级到Grails 2.5.0它的工作原理是Grails 3.*问题.Gradle可能是个问题.

Answer 1

我把一切都包含在Grails 3的一个事务中

qotd.Quote.withTransaction {
  new qotd.Quote(author: 'Larry Wall',
    content: 'There is more than one method to our madness.').save()
}
