Spring框架监控ThreadPoolTask​​Executor队列大小

Question

我查了http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/concurrent/ThreadPoolTaskExecutor.html

队列大小没有getter，只有队列容量。

如果我使用 jmx 来监控 ThreadPoolTask​​Executor，我如何监控队列大小级别以确保它是健康的？

Answer 1

executor.getThreadPoolExecutor().getQueue().size()

@ManagedResource
public class MyTEMBean {

    private final ThreadPoolTaskExecutor te;

    public MyTEMBean(ThreadPoolTaskExecutor te) {
        this.te = te;
    }

    @ManagedAttribute
    public int getQueueSize() {
        return this.te.getThreadPoolExecutor().getQueue().size();
    }

}
