一、使用线程池的好处 池化技术相比大家已经屡见不鲜了，线程池、数据库连接池、Http 连接池等等都是对这个思想的应用。池化技术的思想主要是为了减少每次获取资源的消耗，提高对资源的利用率。 线程池提供了一种限制和管理资源（包括执行一个任务）。 每个线程池还维护一些基本统计信息，例如已完成任务的数量。 这里借用《Java 并发编程的艺术》提到的来说一下使用线程池的好处： 降低资源消耗。通过重复利用已创建的线程降低线程创建和销毁造成的消耗。 提高响应速度。当任务到达时，任务可以不需要的等到线程创建就能立即执

Java中的Timer和TimerTask简介（附完整代码实例）

Java中的Timer和TimerTask简介（附完整代码实例）。 在Java中，Timer和TimerTask是两个经常用来实现定时器的类。这两个类使用起来非常方便，可以完成我们对定时器的绝大多数需求。 Timer是一种定时器工具，用来在一个后台线程计划执行指定任务，并可以按计划一次或反复多次执行一个任务。它是用来执行任务的类，接收一个TimerTask实例作为参数。通常，Timer类有两种执行任务的模式。最常用的是schedule模式，它可以通过两种方式执行任务：在某个特定时刻开始执行任务；从当前时刻开始，在某个固定时段之后开始执行任务。这两种方式都可以指定任务重复执行的频率。另一种执行任务的模式是scheduleAtFixedRate。在这种模式下，Timer类会尽量使任务保持在一个固定的频率下重复执行。 TimerTask一个抽象类，它的子类代表一个可以被Timer计划的任务。

spring task是spring 3.0以后推出的定时器类，可以把它当做一个轻量级的quartz。由于配置简单，功能齐全，在实际项目中经常会用到。spring task支持xml配置、注解配置、java配置三种方式。方式一：xml配置1. 定义任务类package com.sawyer.job;import java.util.Date;public class TaskTest {publi...

开篇在日常的业务开发过程中，可能会需要实现一些周期性定时任务，比如定时同步数据库、定时发送短信 或者 邮件等。那么在 Java 中，共有三种定时任务的实现方式：通过 java.util.Timer、TimerTask 实现。通过 Spring 自带的 SpringTask。(Spring 3.0 以后)通过 Spring 结合 Quartz 实现。而本文说的是第二种方式 - Spring 定时器。...

JAVA里面有时候需要定期地处理某些任务，例如：定期地查询数据库提取数据；定期地清理超时数据；定期地将内存中数据存到数据库。 一种方法是自己写线程，自己控制。另一种方法就是利用java.util.Timer 和 java.util.TimerTask 来实现。 下面就以一个将队列中数据定期存入数据库的例子展示这种用法： import java.util.TimerTask; impor...

Timer和TimerTask可以做为实现线程的第三种方式，前两中方式分别是继承自Thread类和实现Runnable接口。Timer是一种线程设施，用于安排以后在后台线程中执行的任务。可安排任务执行一次，或者定期重复执行，可以看成一个定时器，可以调度TimerTask。TimerTask是一个抽象类，实现了Runnable接口，所以具备了多线程的能力。一个Timer可以调度任意多个TimerTa...
Java常用任务调度

在日常开发过程中，我们经常会遇到周期性执行某段代码的场景。比如定期同步订单，定期更新商品信息，定期发送消息等。这些重复执行的代码可以抽象为一个任务(Task)。 一个Task的特点如下：围绕Task的特点，开发者们开发了不同的调度框架或者中间件，满足日常开发中的使用。以下表格列出了部分实现。本文对部分技术的实现进行了介绍，从简单到复杂，从具体到抽象，希望可以让大家在面对一个任务调度框架时可以快速抓住要点，不再陌生。java.util.Timer位于JDK的rt.jar包下，始于jdk1.3，是JDK自带的任

ForkJoinPool可以给我们提供分⽽治之的功能，当我们有⼤量任务需要处理的时候，我们可以将其分为N个批次，然后每个批次开启⼦线程去并发执⾏，当⼦线程都执⾏完毕后，再对结果进⾏汇总计算。这种思想就类似于Hadoop的MapReduce⽅式。其中，fork表示开启⼀个执⾏分⽀，即：创建⼦线程去执⾏某些任务。⽽join我们在前⾯也介绍过，它具有等待的含义，也就是使⽤fork()后系统多了⼀个执⾏分⽀或执⾏线程，所以需要等待这个分⽀执⾏完毕，才能进⾏最后结果汇总的计算。
