线程错误时停止Spring引导

Question

@Bean
public TaskExecutor a() {
  return new SimpleAsyncTaskExecutor();
}

@Bean
public CommandLineRunner b() {
  return (String... args) -> {
    RunnableTask task = SomeRunnableTask();
    a().execute(task);
  };
}

当线程停止时，关闭Spring引导的正确方法是什么？我不应该使用Spring中的SimpleAsynctAskExecutor吗？

谢谢！

Spring Boot有一个ShutdownEndpoint，它

允许应用程序正常关闭（默认情况下不启用）。

你得在上面看一看：

Thread thread = new Thread(new Runnable() {
    @Override
    public void run() {
        try {
            Thread.sleep(500L); // For the response to be sent back to the requester
        }
        catch (InterruptedException ex) {
            Thread.currentThread().interrupt();
        }
        ShutdownEndpoint.this.context.close();  // The ConfigurableApplicationContext 
    }
});
thread.setContextClassLoader(getClass().getClassLoader());
thread.start();
