Question

我正在运行一个spring-boot应用程序，一切都很好，除非我试图关闭它。我在下面的代码中遇到错误

    while (true) {
        try {
            if(level2List == null)
                break;
            CDR cdr = level2List.poll(2, TimeUnit.SECONDS);

在最后一行产生错误，spring boot在2秒等待完成之前关闭level2List

有没有办法订购关机程序或确保我在关闭之前没有使用level2List？

Answer 1

我做了两件事

添加

@Bean(destroyMethod = "shutdown")
public ThreadPoolTaskExecutor level1ES() {

也

    } catch (InterruptedException e) {
        log.warn("Closing application while CDR still in queue");           }
