  Spring作为低侵入的Java EE框架之一,能够很好地与其他框架进行整合,其中Spring与Hibernate的整合实现的事务管理是常用的一种功能。


	public static void main(String[] args) {
//		Configuration cfg = new Configuration();
//		cfg.configure();
//		SessionFactory sf = cfg.buildSessionFactory();
		Session s = null;
		Transaction tx = null;
		try {
			s = HibernateUtil.getSession();
			tx = s.beginTransaction(); //这里开启了事务
		} catch (HibernateException e) { //如果出现异常,且事务已经开启,则需要回滚。
			if (tx != null)
			throw e;
		} catch (ClassNotFoundException e) {
		} finally { //无论如何都需要关闭Session。
			if (s != null)



  1. @Transactional注解就代表支持事务管理,如果这个注解在类上,那么表示该注解对于所有该类中的public方法都生效;如果注解出现在方法上,则代表该注解仅对该方法有效,会覆盖先前从类层次继承下来的注解。
  2. 一般情况下不要将这个注解加到接口和抽象类上,因为注解是不能被继承的。



  1. propagation参数,Propagation类型(枚举),默认值为Propogation.REQUIRED,支持的值有REQUIRED、MANDATORY、NESTED、NEVER、NOT_SUPPORTED、REQUIRE_NEW、SUPPORTS。关于这个问题的详细说明将在以后的文章中展开。
  2. isolation参数,Isolation类型(枚举),默认值为Isolation.DEFAULT,支持的值有DEFAULT、READ_COMMITTED、READ_UNCOMMITTED、REPEATABLE_READ、SERIALIZABLE。关于这个问题的详细说明将在以后的文章中展开。
  3. timeout参数,int类型,事务的超时时间,默认值为-1,即不会超时。
  4. readOnly参数,boolean类型,true表示事务为只读,默认值为false。
  5. rollbackFor参数,Class<? extends Throwable>[]类型,默认为空数组。
  6. rollbackForClassName参数,String[]类型,默认为空数组。
  7. noRollbackFor参数,Class<? extends Throwable>[]类型,默认为空数组。
  8. noRollbackForClassName参数,String[]类型,默认为空数组。


  但是,如果不配置任何与回滚有关的参数,不代表事务不会进行回滚,如果没有配置这四个选项,那么DefaultTransactionAttribute配置将会生效,具体的行为是,抛掷任何unchecked Exception都会触发回滚,当然包括所有的RuntimeException。

Because Java EE is convention-over-configuration oriented, real-world apps don't require a lot of configuration. When used with Java 8, Java EE 7 has sufficient functionality to handle most use cases without any additional requirements. Given that the deployment implementation is already built into the runtime, Java EE is the ideal platform for container technologies like Docker. If at all possible, Sebastian advises separating business logic from the runtime. diamonds rings for cheap To do this, the programme must be contained in a WAR file that solely contains its code.
