春天和休眠：org.hibernate.Session.getFlushMode()Lorg/hibernate/FlushMode

Question

我正在准备做一个 Web 服务项目，但在开始之前，我决定了解其中的原理。为此，我开发了一个在 Eclipse 中启动良好的应用程序，但是当我尝试从浏览器访问时，我在 Eclipse 控制台中出现了这个异常：

在浏览器中我有这样的消息：

Whitelabel 错误页面 此应用程序没有 /error 的显式映射，因此您将其视为后备。

出现意外错误（类型=内部服务器错误，状态=500）。 无法打开 JPA EntityManager 进行事务处理；嵌套异常是 java.lang.NoSuchMethodError: org.hibernate.Session.getFlushMode()Lorg/hibernate/FlushMode;

我指定我使用 hivernate 5.2.12、spring 4.0.6 和 sqlite 3。我可以说 hivernate 5.2.12 与 spring 4.0.6 不兼容。

当我将 spring 的版本更改为 4.3.12 时，出现以下异常：

提前感谢您的帮助。

org.hibernate.dialect.SQLiteDialect does not support sequences

这意味着您不应该在 SQLite 中使用sequences（生成id）。
