I. Spring Batch Late Binding

See below configuration:

<!-- Abstract Parent Bean -->
<beans:bean id="parentBean" abstract="true">
    <beans:property name="folder" value="${folder}"/>
    <beans:property name="fileName" value="${inputFileName}"/>
</beans:bean> 

The configuration uses a traditional approach:${folder} & ${inputFileName}
folder & inputFileName must define in a configuration file, like application.properties:

folder=C:\\readfile
inputFileName=1.txt
