Spring consolidates quartz for timed tasks

Recently in the project to use the scheduled task, but also take this opportunity to understand some common timing tasks, because the project uses the spring framework, so I will combine the spring framework to introduce.A Classification From the implementation of the technology to classify, there are currently three kinds of technology (or three products) Java comes with the Java.util.Timer class, which allows you to dispatch a Java.util.TimerTask task. Using this method

Quartz cannot directly use existing object instances

Quartz cannot directly use existing object instances Because Quartz must implement the Job interface for all tasks to be executed, and Quartz creates a JobDetail object to execute the task. In the JobDetail constructor, only the constructor that uses Class for parameters is provided. Therefore, you cannot directly use existing instance objects, you must use other

Quartz Framework Quick Start (ii)

Use declarative processing of software configurations as much as possible, followed by programmatic approaches. In the previous Quartz Framework QuickStart (a), if we were to change the execution time and frequency of the Job after it was started, we had to modify the source code recompile. This approach applies only to small example programs, but for a large and complex system, this becomes a problem. Therefore, if you can deploy the quart Job declar
