Spring Boot batch job does not shut down automatically after completion when using JPA #3725
Description
Bug description
I notice that a spring boot batch application does not shut down automatically after completing a job when using Spring data JPA. The job completes successfully but the spring boot application remains running and has to be stopped manually (e.g. by pressing Ctrl + C).
Environment
Spring boot version: 2.3.0.RELEASE
Java version: 1.8
OS: Windows
Steps to reproduce
- Create a new spring boot project from https://start.spring.io/
- Add the following dependencies:
spring-boot-starter-batchspring-boot-starter-data-jpah2
- Create a tasklet step
- Configure a spring batch job referencing the tasklet step
Expected behavior
The job should execute successfully, and shut down automatically.
