Java 如何将AOP建议应用于ConstraintValidator<；A、 T>；春天？
我正试图在Spring3.0.x下编写自己的Java 如何将AOP建议应用于ConstraintValidator<；A、 T>；春天？,java,spring,spring-aop,hibernate-validator,bean-validation,Java,Spring,Spring Aop,Hibernate Validator,Bean Validation,我正试图在Spring3.0.x下编写自己的验证器（根据JSR-303规范） 我用@Transactional注释了isValid（Serializable，CosntraintValidatorContext）方法，但似乎没有将事务性建议应用于此方法-调用isValid（）方法时，调用sessionFactory.getCurrentSession（）会创建异常： hibernate.HibernateException：没有绑定到线程的hibernate会话，并且配置不允许在此创建非事务会话
验证器@TransactionalisValid（Serializable，CosntraintValidatorContext）isValid（）sessionFactory.getCurrentSession（）验证器bean中有一个@Autowired
sessionFactory
，注入时没有问题。我目前的解决方法是使用openSession（）
而不是getCurrentSession（）
，但这涉及到手动事务管理，我希望避免这种情况
在我的验证程序bean的构造函数中进行堆栈跟踪时，我的验证程序bean似乎是通过调用o.s.b.f.s.AbstractAutowireCapableBeanFactory.createBean（）来构造的。我假设这意味着工厂能够在我的验证器中填充@Autowired
字段，但它似乎没有应用任何事务性建议
提前感谢您对此事的帮助
编辑：如果有任何帮助，我已经包含了一个部分堆栈跟踪（通过createnewexception（）
）记录在构造函数中：
