使用JPA和Hibernate在Spring中出錯

Question

我正在遵循這個多元化的教程，以通過JPA和Hibernate理解Spring。我在以下錯誤上停留了幾天。

我是Spring的初學者，無法刪除此類錯誤。 嘗試搜索此錯誤，但未找到任何合適的答案。 任何人都可以幫忙。

Answer 1

您需要運行mvn dependency:tree並檢查是否存在任何Spring 3.xx jar。 在Spring 4.0.x中添加了needsRefresh（）方法，因此在3.0.x版本中找不到該方法。

如果您發現任何Spring 3.xx依賴項，請嘗試排除它們。

Answer 2

錯誤是java.lang.NoSuchMethodError 。 通常，這意味着您的jar版本不正確。 您的Spring版本可能是錯誤的。 嘗試將版本3更改為4
