java - 从 ApplicationListener 关闭 spring 应用程序

Question

是否可以从 ApplicationListener 关闭上下文？

   public class MyListener implements ApplicationListener<ContextRefreshedEvent> {

    @Override
        public void onApplicationEvent(ContextRefreshedEvent event) {
            // on some certain condition we want to shutdown spring ie close the context
        ((ConfigurableApplicationContext)event.getApplicationContext()).close();
        }
    }

问题是Spring仍然想在这里完成启动过程:

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

因此抛出 IllegalStateException:

java.lang.IllegalStateException: org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext@dcb84c98 has been closed already

您真正想问的问题可能是“如何中断 Spring-Boot 启动”。

从 onApplicationEvent 方法引发异常。
