Need automatic app restarts in Elastic BeanStalk after completing the deplyoment with using .platform

I’m currently working on a java project that will be deployed to elastic beanstalk and storing all the sensitive properties to parameter store. My problem is I need to restart the App server on elastic beanstalk after the deployment to get those parameters to work. I need that to be automatically picked up or automatically restart the app server.

Example: I need to store db access details in parameter store and make them available in environment properties in elastic beanstalk and I have done that by adding a bash script file in .platform folder to get the parameters and add them to env files /opt/elasticbeanstalk/deployment/env

For demo App, I'm using java to get the properties through “System.getenv("dbusername");” The scripts are running and I’m able to access the parameter store properties but the problem is I need to restart the App server on elastic beanstalk to work these properties.

Can you please someone suggest to me that I can run the App server automatically once the application is deployment is done?

Let me know if you need any further information related to my issue.
