如果没有活动事务 Hibernate Spring，CreateQuery 无效

Question

您好，我遇到以下问题，当我使用 sessionFactory.openSession(); 时它工作正常但 Session session = this.sessionFactory.getCurrentSession(); 我收到以下错误

DAO

public List<Bank> listbank(String bankId) {

        Session session = this.sessionFactory.getCurrentSession();
        Query query = session.createQuery("from Bank ");
        List<Bank>bankList =query.list();
        session.close();
        return bankList;
    }

错误

org.hibernate.HibernateException: createQuery is not valid without active transaction
    at org.hibernate.context.internal.ThreadLocalSessionContext$TransactionProtectionWrapper.invoke(ThreadLocalSessionContext.java:352)
    at com.sun.proxy.$Proxy86.createQuery(Unknown Source)
    at 

我的应用程序使用 spring 运行并使用 Jersey 进行休眠

Answer 1

你错过了 session.beginTransaction();在你的代码中。 将其放在 Session session = this.sessionFactory.getCurrentSession();

之后
