Package org.springframework.batch.core.jsr

Class JsrJobParametersConverter

  • All Implemented Interfaces:
    JobParametersConverter, org.springframework.beans.factory.InitializingBean
    public class JsrJobParametersConverter
extends java.lang.Object
implements JobParametersConverter, org.springframework.beans.factory.InitializingBean
    Provides default conversion methodology for JSR-352's implementation. Since Spring Batch uses job parameters as a way of identifying a job instance, this converter will add an additional identifying parameter if it does not exist already in the list. The id for the identifying parameter will come from the JOB_SEQ sequence as used to generate the unique ids for BATCH_JOB_INSTANCE records.
