在Java中停止执行几秒钟的最佳方法是什么?

问题描述

我是Java的新手.我试图编写一个程序来检查数据库状态(是否过载).

I am new to Java. I tried to write a program to check database status (overloaded or not).

代码:

package com.test.service;

import java.util.LinkedList;
import java.util.List;

public class PersonImpl {

    public PersonService personService;

    public void InsertPersonDetails(Person person) {

        if(personService.isOverLoaded()) {
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        } else {
            //pass control to dao
        }
    }
}

在这里，我将从isOverLoaded中获取boolean.如果isOverLoaded值为yes，那么我们应该停止将控制传递给dao几秒钟，然后再次检查isOverLoaded方法.

Here I will get boolean from isOverLoaded. If isOverLoaded value is yes then we should stop passing control to dao for few seconds and then check isOverLoaded method again.

我们将不胜感激:)

推荐答案

我会去 ScheduledExecutorService .创建一个线程，只要isOverloaded()返回true，就重新计划执行.

I would go for an ScheduledExecutorService. Create a thread and as long as isOverloaded() returns true re schedule the execution.
