Spring MVC Hibernate集成

Question

如何在Spring MVC中集成hibernateUtil和hibernate.cgf.xml？ Witch XML文件我應該配置dao-context.xml還是store-servlet.xml？ 在此處輸入圖片說明

Store-servlet.xml

如何在Spring MVC中集成hibernateUtil和hibernate.cgf.xml？

• hibernate.cfg.xml ：這是主要的hibernate配置文件，用於加載實體的數據庫配置和映射文件。 這必須是項目內的類路徑位置。 默認情況下，hibernate將查找classpath目錄的根目錄。 如果要使用其他位置，則必須在加載配置時將該位置傳遞給config對象，並且在此處必須定義數據庫詳細信息和映射文件的位置。

• hibernateUtil ：實際上，spring mvc中沒有此類的集成，因此這是一種實現DAO並手動控制Hibernate會話和事務的簡單方法。
