Springboot Scheduled Asynchronous Execution _ asynchronous

In Springboot, it's easy to start a timed task by adding @EnableScheduling annotations to the start class and then adding @scheduled annotations to the method you want to perform regularly to start the timed task. However, this timing task has a hole, that is, it is synchronized, such as two scheduled tasks, the two timing at the same time only one in the execution.
If you want to execute asynchronously, you need to add two annotations, start the class with the @EnableAsync, add @async where you want the asynchronous execution
