默认情况下,Spring要求每个SmartLifecycle阶段的bean在30秒内停止;您可以通过添加以下 bean 来更改该行为:
@Bean
public DefaultLifecycleProcessor lifecycleProcessor() {
DefaultLifecycleProcessor lp = new DefaultLifecycleProcessor();
lp.setTimeoutPerShutdownPhase(120_000);
return lp;
}
编辑
在其侦听器处理批处理时停止容器不会影响批处理的处理;侦听器线程不会被容器杀死;但是,默认情况下,容器会在 10 秒后发布容器停止事件(容器属性 shutDownTimeout),即使侦听器实际上还没有完成。
如果您担心生命周期处理器会在批处理中杀死线程并且不想增加其超时时间,您可以通过暂停消费者和监听事件的组合来执行正常关闭。
这是一个例子:
@SpringBootApplication
public class So61799727Application {
public static void main(String[] args) {
SpringApplication.run(So61799727Application.class, args);
}
@KafkaListener(id = "so61799727", topics = "so61799727", concurrency = "3")
public void listen(List<String> in) {
System.out.println(in);
}
@Bean
public NewTopic topic() {
return TopicBuilder.name("so61799727").partitions(3).replicas(1).build();
}
@Bean
public ApplicationRunner runner(KafkaTemplate<String, String> template,
KafkaListenerEndpointRegistry registry) {
return args -> {
sendTen(template);
System.out.println("Hit enter to pause container");
System.in.read();
registry.getListenerContainer("so61799727").pause();
};
}
public static void sendTen(KafkaTemplate<String, String> template) {
IntStream.range(0, 10).forEach(i -> template.send("so61799727", "foo" + i));
}
}
@Component
class Eventer {
privaate final KafkaTemplate<String, String> template;
private final AtomicInteger paused = new AtomicInteger();
Eventer(KafkaTemplate<String, String> template) {
this.template = template;
}
@EventListener
public void paused(ConsumerPausedEvent event) {
System.out.println(event);
if (this.paused.incrementAndGet() ==
event.getContainer(ConcurrentMessageListenerContainer.class).getConcurrency()) {
System.out.println("All containers paused");
So61799727Application.sendTen(this.template);
}
}
@EventListener
public void idle(ListenerContainerIdleEvent event) {
System.out.println(event);
}
}
