java - 在 hibernate5.1 和 spring 4.1.6 集成中找不到 Hibernatetemplate 的 opensession() 异常

Question

我正在使用 hibernate 5.1.0 和 spring 4.1.6 jar。对于 Hibernate 3.6 jar，它工作正常，但我不想降级我的 hibernate jar。那么 hibernate 5.1 和 spring 4.1.6 集成的解决方案是什么？

Exception in thread "main" java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;

Answer 1

您正在将版本 3 的 HibernateTemplate 与 hibernate 5 一起使用。这是不兼容的。

此外，HibernateTemplate 已被弃用。你应该考虑换成别的东西。
