错误 Spring 和休眠

Question

我运行项目时，会建好数据库，但不会保存数据。 我使用 Postgre 数据库。 添加 Spring 和 Hibernate 以及 Postgre 库。

感谢您帮助我解决问题。

我的代码

public class PersonManager extends HibernateDaoSupport {

    public void RegisterPerson()
    {
        Person person = new Person();
        person.setId(0);
        person.setName("ali");
        person.setFamily("eslami");
       getHibernateTemplate().saveOrUpdate(person);
    }



    public static void main (String[] arg0)
    {
        BeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource("beans.xml"));
        PersonManager aa = (PersonManager) beanFactory.getBean("p");
        aa.RegisterPerson();
    }


    }

Answer 1

NoSuchMethodError: org.hibernate.Session.getFlushMode()Lorg/hibernate/FlushMode

上述错误表示org.hibernate中Session类中的方法getFlushMode()不存在。

hibernate-entitymanager 已在 Hibernate 5.2.0 中删除，而是移至 hibernate-core，由于您使用的是 5.3.0，这就解释了为什么会出现上述错误。

见Spring 4.3.0.RELEASE + Hibernate 5.2.0.Final + JPA Repository

将 hibernate 降级到 5.1.0 应该可以解决您的问题。

或者，您可以使用getHibernateFlushMode 代替getFlushMode，如Hibernate's 5.2 Migration Guide 中所述：

Session#getFlushMode 和 Query#getFlushMode 在以下方面发生冲突 Hibernate (FlushMode) 和 JPA (FlushModeType) 返回。 #getFlushMode 已更改为返回 JPA 的 FlushModeType。冬眠 FlushMode 仍可通过#getHibernateFlushMode 和#setHibernateFlushMode 使用。 Session#getFlushMode 和 EntityManager#getFlushMode 相同。
