嗨,我看到很多人都有这种类型的问题,但答案对我没有帮助
这是我的错误：我认为我必须为sesssionFactory创建bean,但我在你的上下文文件中看到了它.这是春天,冬眠和角度项目mayby角度是一个问题？请帮忙

和DAO

@Repository
public class NewsletterDAOImpl implements NewsletterDAO,Serializable {

    @Autowired(required = true)
    private SessionFactory sessionFactory;

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }


    @Override
    public Newsletter addUser(Newsletter user) {

        getSessionFactory().getCurrentSession().save(user);

        return user;
    }


}

和服务

@Service("newsletterService")
public class NewsletterServiceImpl implements NewsletterService {

    @Autowired
    private NewsletterDAO newsletterDAO;

    @Override
    @Transactional(readOnly = false)
    public Newsletter addUser(Newsletter user) {

       newsletterDAO.addUser(user);

        return user;
    }
}

和控制器

@Controller
public class HomeController {

    @Autowired
    private NewsletterService newsletterService;

    @RequestMapping("/home")
    public String hello(@RequestParam(value="name",required=false,defaultValue="World") String name,Model model) {

        model.addAttribute("name",name);

        return "home";

    }
    @RequestMapping(value = "/home",method = RequestMethod.POST)
    @ResponseBody
    public void addPerson(@RequestBody Newsletter newsletter) {
        newsletterService.addUser(newsletter);
    }

}

和上下文
