Question

我使用的是Spring 4.3.8和Hibernate 5.2.10，我尝试在数据库中创建表并插入记录但我收到错误

Dao Class

@Transactional
    public void saveDayBookData(DayBookData dayBook){
        hibernateTemplate.getSessionFactory().getCurrentSession().setFlushMode(FlushMode.AUTO);
        hibernateTemplate.saveOrUpdate(dayBook);
    }

适用于所有spring和hibernate配置

public static void main(String[] args) {
        // TODO Auto-generated method stub

        Resource r = new ClassPathResource("applicationContext.xml");
        BeanFactory bean = new XmlBeanFactory(r);

        DayBookDao dayBookDao = (DayBookDao) bean.getBean("dayBook");
        DayBookData dayBook =  new DayBookData();
        dayBook.setAccountType("Bank Account");
        dayBook.setTransType("Receipt");
        dayBook.setOppAccount("Profit-Loss");
        dayBook.setAmount(15000);
        dayBook.setTransDate(new Date());
        dayBookDao.saveDayBookData(dayBook);
    }

我收到此错误

    at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:456)

Answer 1

看起来问题就是你创建DAO的方式。

而是将扫描添加到applicationContext.xml

<context:component-scan base-package="com.your.package.here" />

使用@Repository注释DAO类，让Spring为它们创建代理。

删除从xml声明的DAO bean。

我的类似问题已通过以下两种方法得到解决。

通过手动处理交易。

Session session = sessionFactory.getCurrentSession（）; 事务tx = session.beginTransaction（）; UserInfo user =（UserInfo）session.get（UserInfo.class，1）; tx.commit（）;
告诉Spring在您的web.xml过滤器中打开并管理事务并确保使用@Repository @Transactional

＆LT;过滤器＆gt; ＆LT; filter-name＆gt; hibernateFilter＆lt; / filter-name＆gt; ＆LT; filter-class＆gt; org.springframework.orm.hibernate5.support.OpenSessionInViewFilter＆lt; / filter-class＆gt; ＆LT; init-param＆gt; ＆LT; PARAM-名称＆gt;的sessionFactory ＆LT; PARAM值＆GT; session.factory ＆LT; / init-param＆gt; ＆LT; / filter＆gt; ＆LT; filter-mapping＆gt; ＆LT;过滤器 - 名称＆gt;＆hibernateFilter LT; / filter-name＆gt; ＆LT; url-pattern的＆GT; / *＆LT; / url-pattern＆gt; ＆LT; / filter-mapping＆gt;
