There are many open-source frameworks such as quartz, @Scheduled is a timed task annotation of spring, which can be easily and conveniently based on the annotation configuration.First, @Scheduled notes introductionThis is the first place to put @scheduled annotations. Then the following is an introduction to these several properties.* Copyright 2002-2018The origi

Spring @ Scheduled @ Async implements scheduling tasks in combination, @ scheduled @ async The Scheduled task has been using quartz and so on before, but I noticed that Spring actually provides a simple scheduling annotation @ Scheduled, so I just want to try it out .. The Code is as follows: @ Component @ EnableSchedu

The use of annotations is enhanced in Spring3, where the scheduled tasks are enhanced, and it is now only two steps to create a scheduled task: Create a Java class, add a method with no parameter and no return value, and decorate it with @scheduled annotations on the method; Add three Finally, the Java class created in the first step is to be a

As title shows, sometimes we need to configure simple scheduled tasks in a Web project, and because the tasks are not complex and do not want to use a scheduled scheduling framework (Ps:quartz, ActiveMQ, Kafka, etc.), consider using @scheduled annotations to define simple scheduled tasks. Its full configuration is as f

Currently, scheduled operations include: 1. Regular Refresh of Html pages (Refresh-Refresh) 1. Refresh (Refresh) code instructions Note: The time (in seconds) for a webpage to refresh itself, or the time after which the webpage is automatically linked to another webpage. Usage: Note: 5 indicates that the URL is automatically refreshed after 5 seconds. 2. How to perform scheduled operations You can refresh

1. Backup:Ps:2014-1-15If the exported DMP data file is not large, it is exported directly every day, do not save only seven days of data. Then, the file is packaged by WinRAR, and I find that the DMP files are still very compressed.Then you need to consider adding a date to the end of the exported DMP file. The bat script has a function of date and time, and we can get the desired date by the following function. If the requirement date is end with "-", the format of the date needs to be yyyy-m-d

Once the framework uses the Quartz framework to run timing scheduling problems,The boss said that the configuration is too cumbersome, each scheduling needs to be more in the spring configuration,Can reduce the amount of configuration to improve development efficiency,Recently, we have looked at spring's scheduled using annotations to dispatch,Feel very convenient, at least the configuration of things less very much,So stay for forgetting,First, we ne

Regular tasks have always been a problem for many friends in PHP, but they are encountered in many places.For example:In game development programs, send troops to players every 10 minutesIn the SNS community, check if someone sends me a message every 20 seconds.The automatic collection program collects the latest content every 5 minutes.Weibo Data Synchronization: user data is synchronized every 10 hours through the Weibo API......
