java.lang.NoSuchMethodError : org. hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;

Question

我在 struts2-fullhibernatecore-plugin 的帮助下链接 Struts2 和 hibernate。

不幸的是我得到了这个错误。我发现问题可能出在我的 hibernate 版本的类路径上。

这是我的pom.xml。 它现在已经过编辑并且可以完美运行:

这是错误:

有人可以看看我的 pom 说那里有什么问题吗？

Answer 1

当一个库(即 struts2-fullhibernatecore-plugin)针对一个版本的依赖项(即 hibernate)编译但针对另一个版本运行时，会发生“NoSuchMethodError”。

从命令行运行以下命令:

mvn dependency:tree

并查看 struts2-fullhibernatecore-plugin 期望的 hibernate 版本。

我猜您会发现 struts2-fullhibernatecore-plugin 需要特定版本的 hibernate。但是由于您在 pom 中明确定义了一个 hibernate 版本，所以 maven 改用这个版本。查看最近的定义 wins strategy here .

要修复，请将 pom.xml 中的 hibernate 版本更改为 struts2-fullhibernatecore-plugin 所需的版本。
