Why Spring Batch reads metadata tables from MASTER and not from User defined Schema?

问题

I have a spring boot batch application. In application.properties, i specify my datasource details as follows

spring.datasource.url=jdbc:jtds:sqlserver://1*.2**.6*.25:14**
spring.datasource.database=MYDB_DEV
spring.datasource.username=username
spring.datasource.password=password

The problem is, when i run the batch job, all user defined tables are taken from the MYDB_DEV. But Metadata tables like BATCH_JOB_EXECUTION, BATCH_JOB_EXECUTION_CONTEXT are taken from the MASTER schema even though i have created the same tables in MYDB_DEV. Why this happens? Is there any work around to make the application read Metadata tables from user defined schema?

I have debugged though the jobLauncher.run(myjob, jobParameters), Could not find any lead from where it is taking master Schema

回答1:

Use below property in application.properties or application.yml

spring.batch.tablePrefix=MYDB_DEV.BATCH_
