春季啓動JPA integreated使用JavaFX服務空

我已經集成春天啓動JPA使用JavaFX應用程序。整合是成功的，FX屏幕加載場景，問題是服務在@Autowired註釋字段上變爲空。你可以在github上找到我的整個項目boot-fx。春季啓動JPA integreated使用JavaFX服務空

Entity

@Entity 
@Table(name = "LW_BLOOD_GROUP") 
public class BloodGroup implements Serializable { 
    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    @Column(name = "ID", nullable = false, length = 11) 
    private int id; 
    @Column(name = "GROUP_NAME", nullable = false) 
    private String groupName; 
    @Column(name = "CREATED_DATE", nullable = false) 
    private Date createdDate; 
    @Column(name = "IS_DELETE", nullable = false) 
    private boolean isDelete; 

    public BloodGroup() { 
     super(); 
    } 
//getters and setters 
}

Repository

@Repository 
public interface BloodRepository extends JpaRepository<BloodGroup, Integer>{ 
}

serviceimpl

@Service 
public class BloodGroupServiceImpl implements BloodGroupService{ 
    @Autowired 
    private BloodRepository bloodRepository; 
    @Override 
    public Collection<BloodGroup> findAllBloodGroup() { 
     return bloodRepository.findAll(); 
    } 
}

fx controller

@Component 
public class HomeController implements BootInitializable { 
    private ApplicationContext springContext; 
    @Autowired 
    private BloodGroupService bloodGroupService; 
    @Autowired 
    private BloodRepository bloodRepository; 

    @Override 
    public void initialize(URL arg0, ResourceBundle arg1) {} 

    @Override 
    public void setApplicationContext(ApplicationContext arg0) throws BeansException { 
     this.springContext = springContext; 
    } 

    @Override 
    public void initConstruct() {} 

    @Override 
    public void stage(Stage primaryStage) {} 

    @Override 
    public Node initView() { 
     try { 
      FXMLLoader loader = new FXMLLoader(); 
      loader.setLocation(getClass().getResource(Screens.HOME)); 
      //loader.setController(springContext.getBean(this.getClass())); 
      return loader.load(); 
     } catch (IOException e) { 
      System.err.println("can't load scene"); 
      e.printStackTrace(); 
      return null; 
     } 
    } 

    @FXML 
    private void addMemberSelect(){ 
     if(bloodRepository!=null){ 
       System.out.println("service initialized"); 
      }else{ 
       System.out.println("service null"); 
      } 
    } 

}

控制器你爲什麼註釋掉'loader.setController（...）'行？你不需要'loader.setController（this）;'那裏？ –

因爲我已經在fxml頁面上指定了控制器。 – boycod3

但是這是一個創建控制器類的新實例的指令（即一個不是由Spring管理的實例）。刪除'fx：controller'屬性並使用'loader.setController（this）' –

@James_D找到我的代碼的問題。我已經在fxml頁面中指定了控制器。按照詹姆斯建議刪除從FXML控制器FXML像loader.setController(this)
