UnsatisfiedDependencyException - Spring Boot + Hiberate + PostgreSQL

Question

我正在尝试创建一个简单的Spring应用程序，它通过Hibernate集成PostgreSQL 我面临 org.springframework.beans.factory.UnsatisfiedDependencyException ，因为Spring无法检索 org.hibernate.SessionFactory 。

堆栈跟踪如下：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'feedbackDaoImpl' defined in URL [jar:file:/Users/chuajiesheng/Documents/Workspace/spring-hibernate/target/spring-hibernate-0.0.1-SNAPSHOT.jar!/demo/dao/impl/FeedbackDaoImpl.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.hibernate.SessionFactory]: : No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我的 servlet-context.xml 如下所示：

虽然我的 demo.dao.impl.FeedbackDaoImpl 看起来像这样：

package demo.dao.impl;

import demo.dao.FeedbackDao;
import demo.domain.Feedback;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Configurable;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository("feedbackDaoImpl")
public class FeedbackDaoImpl implements FeedbackDao {

    private final SessionFactory sessionFactory;

    @Autowired
    public FeedbackDaoImpl(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    @Override
    public void save(Feedback p) {
        Session session = this.sessionFactory.openSession();
        Transaction tx = session.beginTransaction();
        session.persist(p);
        tx.commit();
        session.close();
    }

    @SuppressWarnings("unchecked")
    @Override
    public List<Feedback> list() {
        Session session = this.sessionFactory.openSession();
        List<Feedback> feedbackList = session.createQuery("from Feedback").list();
        session.close();
        return feedbackList;
    }

}

有人可以指出我的设置有什么问题吗？

非常感谢你的帮助！
