我真的很新用Spring 我正在使用JSF + Hibernate + Spring开发一个简单的JEE应用程序 尝试更新DAO上的值时，我遇到了一些问题 我确定问题与Spring配置xml文件有关，但我无法找到它是什么。

这是我的配置文件：

5 个答案:

答案 0 :(得分：4)

我认为你应该添加一个事务管理器bean。

Fragment.prototype.__defineGetter__('event', function(){
  return this.get('event');
});

和

为应该成为交易的方法添加<tx:annotation-driven/> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> 注释。

希望这有帮助。

答案 1 :(得分：2)

尝试改变这一点：

  <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

使用：

 <bean id="sessionFactory" class="org.springframework.orm.hibernate4.HibernateTransactionManager">

答案 2 :(得分：2)

更改了xml配置文件和DAO 我收到以下错误：

答案 3 :(得分：0)

您可以通过以下方式解决问题：

  1. 在保存时检查Bean / Model类提供的所有必需数据。
  2. 检查是否遵循唯一约束的概念，如果没有，请在唯一列中添加其他数据。
  3. 如果问题仍未解决，则在方法上方添加@Transaction批注，但要使用@Transaction方法创建HibernateTransactionManager的对象
@Bean
public HibernateTransactionManager transactionManager() {
           HibernateTransactionManager txManager = new HibernateTransactionManager();
           txManager.setSessionFactory(getLocalSessionFactoryBean().getObject());

return txManager;

  }

答案 4 :(得分：0)

如果您使用Java配置，只需添加@EnableTransactionManagement（org.springframework.transaction.annotation.EnableTransactionManagement）
