如何使用 Swing 应用程序配置 spring-boot [英] How to configure spring-boot with swing application

问题描述

我想使用 spring-boot-starter-data-jpa 功能来创建非 Web 应用程序.在 52.4 文档中说:

I'd like using spring-boot-starter-data-jpa features to create a non-web aplication. In the 52.4 documentation says:

您希望作为业务逻辑运行的应用程序代码可以是实现为 CommandLineRunner 并作为@Bean 定义.

Application code that you want to run as your business logic can be implemented as a CommandLineRunner and dropped into the context as a @Bean definition.

我的 AppPrincipalFrame 看起来像:

@Component
public class AppPrincipalFrame extends JFrame implements CommandLineRunner{

private JPanel contentPane;

@Override
public void run(String... arg0) throws Exception {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                AppPrincipalFrame frame = new AppPrincipalFrame();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

和启动应用程序类看起来像:

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {  
  public static void main(String[] args) {
   ApplicationContext context = SpringApplication.run(Application.class, args);
   AppPrincipalFrame appFrame = context.getBean(AppPrincipalFrame.class);
  }
}

但是不起作用.有人有这方面的样本吗?

But does not work. Anybody have a sample about this?

已编辑并添加了例外.

Exception in thread "main" org.springframework.beans.factory.BeanCreationException:      Error creating bean with name 'appPrincipalFrame'.

Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [es.adama.swing.ui.AppPrincipalFrame]: Constructor threw exception; nested exception is java.awt.HeadlessException 

问候.

推荐答案

你发布问题已经有一段时间了，但我在一个旧项目中遇到了同样的问题，我正在迁移并想出了不同的方法，我认为这更清楚，让事情发挥作用.

It's been a while since you posted the question, but I run out with the same problem in a old project that I'm migrating and figured a different way, I think that more clear, to make the things work.

代替使用 SpringApplication.run(Application.class, args); 你可以使用:new SpringApplicationBuilder(Main.class).headless(false).run(args); 并且没有必要让玩具应用程序类从 JFrame 扩展.因此，代码可能如下所示:

Instead of using SpringApplication.run(Application.class, args); you can use: new SpringApplicationBuilder(Main.class).headless(false).run(args); and it isn't necessary to make toy Application class extends from JFrame. Therefore the code could look like:

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {  
    public static void main(String[] args) {
    ConfigurableApplicationContext context = new SpringApplicationBuilder(Application.class).headless(false).run(args);
    AppPrincipalFrame appFrame = context.getBean(AppPrincipalFrame.class);
}
