如果没有映射fxml,这段代码运行完美并加载fxml
如果我映射fxml获取异常 我尝试了很多,但无法理解是什么问题......
SpringFxmlLoader类方法load()返回语句没有返回任何因为我认为异常发生的事情

答案 0 :(得分:1)
您忘记在LoginPageController
课程中添加Stereotype,这就是Spring告诉您的原因:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'test.spring.boot.LoginPageController'
由于未标记类,组件扫描将忽略它,并且不会为该类型分配bean寄存器。
尝试:
@Controller
public class LoginPageController implements Initializable{
@Autowired
public LoginPageController(UserService userService, private StageManager stageManager){
this.userService = userService;
this.stageManager = stageManager;
}
}
