In this article, we demostrate how to define the scheduled tasks in a Spring Boot Application.
In enterprise applications, it is often necessary to add follow-up processing to web requests, or perform some timed tasks, such as: Scheduled cleaning of temporary tables, Scheduled summary of data, etc. Spring Boot provides good support for this type of task, and it is very convenient to develop.
In fact, Spring Boot provides at least two ways to perform scheduled tasks： One is to use @Async annotation, Another is to use @Scheduled annotation.
To define a task that executes asynchronously, all you need to do is to add @Async to the method in the container-managed bean. The most common approach is to define a task as a container-managed bean, annotate it with @Component, and then annotate the method you want to execute with @Async:
Calls can then be made where appropriate, such as in business-layer code, which can be written as:
Defines a container-managed Bean in which the method is defined as scheduled execution:
The above code is executed every minute.
