org.springframework.orm.jpa.EntityManagerHolder不能轉換爲org.springframework.orm.hibernate5.SessionHolder

我試圖使用Spring4與Hibernate5，但我得到這個錯誤：org.springframework.orm.jpa.EntityManagerHolder不能轉換爲org.springframework.orm.hibernate5.SessionHolder

org.springframework.orm.jpa.EntityManagerHolder cannot be cast to org.springframework.orm.hibernate5.SessionHolder

我改變很多次我的pom.xml

的pom.xml

其他情況下你有沒有嘗試排除改變'JpaRepositoriesAutoConfiguration'爲'HibernateJpaAutoConfiguration'，看看發生了什麼事？ – xsalefter

我排除此之前。我得到：> org.springframework.data.jpa.repository.support.DefaultJpaContext中的構造函數的參數0需要一個無法找到的類型爲'java.util.Set'的bean。 – Tineo

@Tineo你能解決它嗎？ – Sikorski

的配置是正確的，但你可以注入的EntityManager而不是SessionManager。

如您所知，EntityManager與JPA協同工作，SessionManager與Hibernate協同工作。

請檢查您的DAO，並使您剛剛注入SessionManager。

在你的問題是與spring boot
