Quartz is an open-source job scheduling framework that is written entirely in Java and designed for use in J2SE and Java EE applications. It provides a great deal of flexibility without sacrificing simplicity. You can use it to create simple or complex schedules for executing a job.In the project has a large number of background tasks need to schedule execution, such as building indexes, statistical reports, periodic synchronization data and so on, re

Today, we use spring to integrate quartz for Task Scheduling in a new project. As in the past, we have configured jobdetail, trigger, and schedulerfactorybean to start, but encountered the following exception:Org. springframework. Beans.

Integrated Use of Quartz and Spring
I have mentioned the basic use of Quartz before). In actual use, we usually hand over scheduled tasks to the spring container for management. So today we will talk about the integration of Quartz and spring.
Let's talk about integrated use in the order of the three elements of Quartz.Job
In spring, job task management for
About the timing of the operation of the task, the Java language itself with a timer to solve, but the timer function is not particularly comfortable, due to the needs of the project, the use of quartz This scheduling framework, the learning process is recorded, convenient to consult later.

By default, JBoss EJB uses timerservice as the scheduled service, which is cumbersome to use. A stateless servicebean is required to implement the scheduletimer and timeouthandler methods, in addition, the timer frequency should be started and controlled through external calls. Timerservice timer is difficult to use during use. Therefore, we hope to use quartz as a server timer. If you use the quartz timer,
Quartz is the point of the Open Source task scheduling framework and provides a powerful task scheduling mechanism. Typical enterprise application scheduling, such as the forum: every half an hour to generate the essence of the article rss, every morning to count the user's points ranking.
The above-mentioned scheduling scenario core is to focus on the point of time scheduling, in fact, also includes resource scheduling. For example, when a Web server
