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
