Question

我正在关注使用JPA和Hibernate理解Spring的this复数教程。我在下面的错误中停留了几天。

我是Spring的初学者，无法删除此类错误。尝试搜索此错误，但没有找到任何合适的答案。任何人都可以帮助我。

Answer 1

你需要跑步 mvn dependency:tree并检查是否有任何Spring 3.x.x jar。在Spring 4.0.x中添加了needsRefresh（）方法，因此无法在3.0.x版本中找到它。

如果您发现任何Spring 3.x.x依赖项，只需尝试排除它们。

Answer 2

错误为java.lang.NoSuchMethodError。它通常意味着你有错误版本的罐子。可能你的Spring版本错了。尝试将版本3更改为4
