java - Initialize Spring batch DB before application bean is created -

i'm trying create bean so:

@bean public clock clock(jobexplorer explorer, environment environment) {    // check last run time of job , create clock bean } 

but when application starts up, error: ora-00942: table or view not exist because spring batch schema hasn't been created spring boot's batchautoconfiguration yet.

then, tried this:

 @bean  @conditiononbean(batchdatabaseinitializer.class)  public clock clock(jobexplorer explorer, environment environment) {    // check last run time of job , create clock bean  } 

this shifted error when clock bean created when bean requiring clock created:

@bean(name = "reader") public itemreader<record> itemreader(               jdbctemplate jdbctemplate, clock clock) {      // create item reader } 

error: no qualifying bean of type [java.time.clock] found dependency

this keeps cascading. if put @conditionalonbean on itemreader method, when bean requires itemreader created, same "no qualifying bean" error.

so, how make sure spring batch schema initialized before beans created?

have tried use @dependson() annotation? not aware of conditiononbean..
