Spring框架监控ThreadPoolTaskExecutor队列大小

Question

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

没有队列大小的getter，只有队列容量。

如果我使用jmx监视ThreadPoolTaskExecutor，我如何监视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();
    }
}
