What this article shares with you is about how to choose executable tasks when springBoot starts. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

CommandLineRunner

The source code is described as follows:

Spring Batch jobs. Runs all jobs in the surrounding context by default. Can also be used to launch a specific job

By providing a jobName .

That is, batch processing starts when the spring container starts. It is loaded and run when spring starts.

How to use: customize a model to implement the and interface and override the run method

Package org.springboot.sample.runner

Import org.springframework.boot.CommandLineRunner

Import org.springframework.stereotype.Component

@ Component

Public class MyStartupRunner implements CommandLineRunner {

@ Override

Public void run (String... Args) throws Exception {

System.out.println ("> service startup execution, perform operations such as loading data > service startup execution 2222 > service startup execution 111111
