020 Asynchronous tasks

I. Overview

In our environment, we often create asynchronous tasks, and our biggest idea is not to let time-consuming tasks block the operation of our methods.

Two. How to use

It's very easy to use asynchronous tasks in Springboot, we only need two steps to complete

[1] Open Async

[2] Defining Async methods

Let's take a look at one of our demo examples:

We just need to add an annotation that initiates an asynchronous task on our main startup class

@SpringBootApplication@EnableAsync   Public class Springbootapplicationstarter {        publicstaticvoid  main (string[] args) {        Springapplication.run (springbootapplicationstarter. class , args);}    }

@Service Public classasynctask { @Async  Public void Async()  {        Try{TimeUnit.SECONDS.sleep (3); } Catch(interruptedexception e) {//TODO auto-generated Catch blockE.printstacktrace (); } System. out. println ("Task Complete"); }}

On our business code, add a note of an asynchronous task to it.
