How to java-configure separate datasources for spring batch data and business data? Should I even do it?

Question

My main job does only read operations and the other one does some writing but on MyISAM engine which ignores transactions, so I wouldn\'t require necessarily tr

Answer 1

Assuming you have 2 data sources, one for spring batch metadata such as job details[lets say CONFIGDB] and other for your business data [lets say AppDB]:

Inject CONFIGDB into jobRepository, like this:

Now you can inject the AppDB dartasource into your DAO's OR Writers if any like..

OR

you can do define a resource and Inject this AppDB with jndi lookup in the class where its needed like:

public class ExampleDAO {

@Resource(lookup = "java:comp/env/jdbc/AppDB")
DataSource ds;

}
