I want to migrate from one database to other using Spring Batch and Spring Boot. I have learnt that we have to declare @Bean for step, Job, JobLauncher, ItemWriter, ItemReader. But for those beans to be created, the database url,username and password is to be declared in the application.properties file. But I want to create them dynamically. By this I mean that I will give the database details at runtime for example in api request body. Is this possible?. I tried coding it but giving a lot of errors. And I don’t know the tables in the database. There are multiple schemas and tables.
