Question

我被困在这里几天没有到达任何地方。这是合约。我正在构建一个使用springboot（主要是使用crudeRepository）和javafx和hibernate的应用程序。

但我不断收到此错误：

这是因为crudrepository clientRepo为null，不知道为什么......在正常执行中它应该有这样的东西：

正如@minus指出的那样，我创建了一个springBoot EntryPoint，但应用程序启动并退出...我从未看到过javaFX视图。

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Lazy;


@SpringBootApplication
public class LaunchClass {

    public static void main(String[] args) {
        SpringApplication.run(MainApp.class, args);

    }

}

Answer 1

你想要达到的目标并不像看起来那么容易。

您可以开始阅读this article或this，然后继续阅读。

事实上，将javafx和Spring + Hibernate结合起来有几个问题。

最大的问题是范围。

Spring和Hibernate大部分都是在Web应用程序中开发的，这些应用程序具有一些定义明确的范围（应用程序，会话，请求）。

JavaFX没有固有的范围，您必须创建自定义范围并进行管理。

同样，Spring和JafaFX FXMLLoader都应该在同一个对象（控制器）中注入字段，这是一个非常重要的细节。

最后但并非最不重要的是管理和确定Hibernate会话的范围。

这是很多工作，我知道这是因为我做了一些与WELD + JavaFX非常相似的事情。

Answer 2

我终于做到了！按照@jewelsea给出的提示，我研究了由Felix Roske创建的框架。它花了一些代码重构，主要是在控制器部分。

App.java 进口......

@SpringBootApplication
public class App extends AbstractJavaFxApplicationSupport {

    /**
     * Note that this is configured in application.properties
     */
    @Value("${app.ui.title:PJe Midia Monitor}")//
    private String windowTitle;



    public static void main(String[] args) {

        launchApp(App.class, VisaoView.class, args);
    }

}

2-视图类

imports ....


@FXMLView(value = "view/visao.fxml")
public class VisaoView extends AbstractFxmlView {

}

3-控制器

imports ....

        audTable.setItems(getAudData());

    public void setAudData(ObservableList<Audiencia> audData) {
        this.audData = audData;
    }

}
