What is %some property% expression in spring

Question

I found %% expression on spring batch source. Is this SpEL? How do I use %% expression?

protected String getQuery(String base) {
    return StringUtils.replace(base, "%PREFIX%", tablePrefix);
}

Hi Can you copy paste Spring code in your question instead of providing a picture ? — Antonin, Dec 20 '21 at 15:24

This is not spel. It's used to replace the string with some target value. For example,

String base = "How are me?";
String target = "me";
String replacement = "you";
String result = StringUtils.replace(base, target, replacement);

Thank you,I know replace util, I want to know what "%PREFIX%" expression is and how to use this. – Jason Moon Dec 28 '21 at 06:21
it is used to modify the template query. See this => private static final String SQL_DELETE_BATCH_JOB_EXECUTION = "DELETE FROM %PREFIX%JOB_EXECUTION where CREATE_TIME < ?"; – Navneet Singh Dec 28 '21 at 06:26
