Spring整合注解的hibernate

Question

我不知道spring要何方神圣才能使用 ，已经配置两周了 ，一直一直一直一直一直配置出错！！！！！！！！
问题就出在这段配置上，百度前面10页的各种方法都用了 ，我不知道一个Spring框架的出现到底是为了在配置上体现出它高超的技术还是为了真的方便管理，起码我孤陋寡闻，配置两周了，我只知道它在配置上确实是用着超高的技术要求，看不到它的其他有点

这个问题是由于Spring Boot中Hibernate整合时，没有正确配置Spring Data JPA。以下是一个解决此问题的方法：

首先，确保你的项目中包含以下依赖项：

• Hibernate
• Spring Data JPA
• Spring Boot

然后，在application.properties文件中添加以下内容：

spring.jpa.show-sql=true
spring.datasource.url=jdbc:mysql://localhost:3306/testdb
spring.datasource.username=root
spring.datasource.password=passw0rd
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto=create-drop
spring.data.jpa.repository.config.annotation.EnableJpaRepositories
spring.data.jpa.repository.config.EnableJpaAuditing

接下来，创建一个新的Spring Data JPA配置类（例如：DormitoryRepositoryConfig.java)，并在其中实现@Repository接口，并继承自AbstractNativePersistenceService. 这样就可以将Hibernate与Spring Data JPA整合在一起。

最后，修改你的DormitoryRepository.java类以使用Spring Data JPA。

import org.springframework.data.jpa.repository.JpaRepository;
import com.example.tables.Dormitory;

public interface DormitoryRepository extends JpaRepository<Dormitory, Long> {
}

现在，你可以在任何地方注入这个Repository，Spring Boot会自动调用Spring Data JPA进行数据库操作。
