springboot&x2B；冬眠+；javaFX

我被困在这里面好几天，一事无成。 下面是交易..我正在构建一个应用程序，它使用springboot（主要是使用crudeRepository）和javafx和hibernate

但我一直在犯这样的错误：

发生这种情况是因为crudepository clientRepo为null，不知道为什么…在正常执行中，它应该有如下内容：

org.springframework.data.jpa.repository.support。SimpleJpaRepository@5a0a3243

任何人，知道为什么吗？先谢谢你

ClientRepo.java 进口

/*TODO essa classe deve implementar o CrudRepository
que vem do spring-DATA-core
*/
@Repository
public interface ClientRepo extends CrudRepository<Client, Integer> {

}

@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);
    }

}

你想要达到的目标并不像看上去那么容易

你可以开始阅读，或者从那里继续前进

事实上，结合javafx和Spring+Hibernate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，web应用程序具有一些定义良好的范围（应用程序、会话、请求）

JavaFX没有固有的作用域，您必须创建自定义作用域并对其进行管理

还有一个非常重要的细节，Spring和JafaFX FXMLLoader都应该在同一个对象（控制器）中注入字段

最后但并非最不重要的是管理和确定Hibernate会话范围的问题

这是一个很大的工作，我知道这一点，因为我用WELD+JavaFX做了一些非常类似的事情。

我终于做到了！ 根据@jewelsea给出的提示，我研究了由创建的框架。这需要对代码进行一点重构，主要是在控制器部分

App.java 进口

/*TODO essa classe deve implementar o CrudRepository
que vem do spring-DATA-core
*/
@Repository
public interface ClientRepo extends CrudRepository<Client, Integer> {

}

@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);
    }

}

我看不到您的Spring Boot入口点。如果我确实了解您想要什么，您的意思是

publicstaticvoidmain（String[]args）{Application.launch（args）；}

这是标准的JavaFX入口点，但我看不到Spring上下文开始。正如您所指出的，应用程序没有Spring入口点……所以我创建了一个（编辑了原始的PostLaunchClass.java）。但现在，应用程序运行…并退出。我在这里迷路了。lolFWIW和我从来没有试过。有一个图书馆和一个图书馆。我建议您尝试一下。先生，谢谢您的回复…我将尝试看看是否有更好的方法来实现这一点，并在稍后发布一些反馈！我解决了这个问题，我是说……某种程度上……重构了整个应用程序。移除了spring引导，并单独使用javaFX+hibernate，它可以正常工作。但是，在不久的将来，我会尝试jewelsea引用的教程。cyaGood，从基础开始总是明智的做法，然后，当你有坚实的基础来构建时，再迈出一步。正如我所说，我确实重构了项目，现在又重构了项目
