Question

我收到了java.net.BindException。我使用Spring自动装配所有bean，所以我不认为同一进程的两个线程正在运行。我也为所有进程使用不同的端口。

可能导致此错误的原因是什么？有没有办法检查原因？

编辑：我得到了错误的来源。我正在使用实现@Component的Spring ApplicationListener<ContextRefreshedEvent>。此组件在tomcat启动时运行，但是当我运行单元测试时，它会再次运行Component。为什么会这样？

以下是供参考的组件 -

@Component
public class RunBackgroundServices implements ApplicationListener<ContextRefreshedEvent> {

    private final BackgroundServices backgroundServices;

    private ExecutorService executor;

    @Autowired
    public RunBackgroundServices(BackgroundServices backgroundServices) {
        this.backgroundServices= backgroundServices;
    }

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {

        executor = Executors.newSingleThreadExecutor();
        executor.submit(backgroundServices);
    }

    public void onApplicationEvent(ContextStoppedEvent event) {
        executor.shutdown();
     }
}

Answer 1

您使用的端口是什么？看起来你阻止了那个端口，你就不会释放它。

试试这个。

     Linux: netstat -lpn | grep "your port" Then with the pid. kill -9 pid

     Mac: lsof -i tcp:"your port" Then with the pid. kill -9 pid

Spring中的java.net.BindException
