public class PostController 
{

    @Autowired
    PostService postService;

    @RequestMapping(value="", method=RequestMethod.GET)
    public String list(Model model){
        model.addAttribute("listData",postService.listPosts());

        return "list";
    }

}

我的服务等级

@Service
public class PostServiceImpl implements PostService{

    @Autowired
    PostDao postDao;

    @Override
    public List<Post> listPosts() {
        return postDao.listPosts();
    }

}

我的存储库类

@Repository
public class PostDaoImpl implements PostDao{

    @Autowired
    private SessionFactory sessionFactory;

    public PostDaoImpl(){}

    public PostDaoImpl(SessionFactory sessionFactory){
        this.sessionFactory=sessionFactory;
    }

    @Override
    @Transactional
    public List<Post> listPosts() {

        @SuppressWarnings("unchecked")
        List<Post> listPost2 = (List<Post>) sessionFactory.getCurrentSession().createQuery("from Post");

        return listPost2;
    }

}

推荐答案

我已经解决了.我已经删除了我的配置类的这一部分，它已经解决了.

I have solved it. I have removed this part my config class and it's solved.

  @Bean
  public HibernateTransactionManager transactionManager() {
    HibernateTransactionManager transactionManager = 
        new HibernateTransactionManager();
    transactionManager.setSessionFactory(sessionFactory().getObject());
    return transactionManager;
