@Transactional spring事务

Question

业务bean：
[color=blue]@Transactional[/color]
public class PersonServiceBean implements PersonService {
@Resource private SessionFactory sessionFactory;

public void save(Person person){
sessionFactory.getCurrentSession().persist(person);
     session,persist()
}

public void update(Person person){
    sessionFactory.getCurrentSession().merge(person);
}

[color=red]@Transactional(propagation=Propagation.NOT_SUPPORTED,readOnly=true)[/color]
public Person getPerson(Integer personId){
    return (Person)sessionFactory.getCurrentSession().get(Person.class, personId);
}

public void delete(Integer personId){
    sessionFactory.getCurrentSession().delete(
            sessionFactory.getCurrentSession().load(Person.class, personId));
}

}

spring配置文件：

问题：[/b]
这个方法已经为只读，但仍能保存进数据库
业务bean已经被@Transactional了。
如果我在save（）方法上在注明@Transactional(propagation=Propagation.SUPPORTES)的话，可以生效！！
什么原因？貌似管理也有啊！！！

Answer 1

大哥，你又用@Transactional注解事物，又用aop的expression正则配置方法事务。两者已经冲突了。

@Transactional在类当中配置全局事务，已经覆盖了你xml文件配置的声明式事物。

去掉类当中的@Transactional就ok了。
