Peter Rader•10mo ago

Hm, I think I see whats the problem.... Do you ever heard of dependency-injection?

DanixOP•10mo ago

yeh

Peter Rader•10mo ago

Well DaoEntityImp is a spring bean. And only spring should create an instance of the type. But in the class login you create your own instance.

Try

@PostMapping("/loginResult")
    public String loginResult(@ModelAttribute LoginPojo loginpojo , Model model ) {
        Model name =  model.addAttribute("name", loginpojo.getUsername());
        
        DaoEntity daoEntity = new DaoEntity();
        daoEntity.setName(loginpojo.getUsername());
        daoEntity.setEmail(loginpojo.getEmail());
        daoEntity.setPassword(loginpojo.getPassword());
        
        //DaoEntityImp daoEntityImp = new DaoEntityImp();
        daoEntityImp.saveUser(daoEntity);
        return "LoginSuccess";
        
    }
    @Autowired
    DaoEntityImp daoEntityImp;

@PostMapping("/loginResult")
    public String loginResult(@ModelAttribute LoginPojo loginpojo , Model model ) {
        Model name =  model.addAttribute("name", loginpojo.getUsername());
        
        DaoEntity daoEntity = new DaoEntity();
        daoEntity.setName(loginpojo.getUsername());
        daoEntity.setEmail(loginpojo.getEmail());
        daoEntity.setPassword(loginpojo.getPassword());
        
        //DaoEntityImp daoEntityImp = new DaoEntityImp();
        daoEntityImp.saveUser(daoEntity);
        return "LoginSuccess";
        
    }
    @Autowired
    DaoEntityImp daoEntityImp;
