Hello @Bouali Ali,
We have a Spring Batch application which validates the flat file in the item reader and throws an exception if the file isn't valid. Can you give more details about how we can handle this scenario?

I do it the same way as him, and it doesn't create the tables for me. The only thing that changed is the Spring Boot version when I downloaded the project to version 3.3.5

The parameter placeholder, . For job Parameters I see Invalid property of bean class StepContext, Bean property is not readable or has invalid getter method, does the return type of getter match the parameter type of the setter?

I have followed the tutorial, but the tables related to Spring Batch are not getting created during the startup of the application. In the application.yaml file, I have configured the to always, which should normaly trigger the initialization of the Spring Batch schema during application startup. But it's not working as expected.

Hi, is someone else have issues when configuring the database ? I have the following error:
Error: [28P01] FATAL: password authentication failed for user "...".

My application.yml file looks OK the user and password are the same, thanks.
