你可以使用以下方法完成此操作：
SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);
其中，entityManagerFactory是一个JPA
EntityManagerFactory。
package net.andreaskluth.hibernatesample;import javax.persistence.EntityManager;import javax.persistence.EntityManagerFactory;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;@Componentpublic class SomeService { private SessionFactory hibernateFactory; @Autowired public SomeService(EntityManagerFactory factory) { if(factory.unwrap(SessionFactory.class) == null){ throw new NullPointerException("factory is not a hibernate factory"); } this.hibernateFactory = factory.unwrap(SessionFactory.class); }}
