JSTL 숫자 천단위 콤마(쉼표) 찍기

JSTL의 fmt:formatNumber 이용하면 된다.

예제1)

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

fmt 미적용 총가격: ${total_amount}원 <br>
fmt 적용 총가격: <fmt:formatNumber value="${total_amount}" type="number" groupingUsed="true"/>원

결과:

*jstl → fmt

예제2)
1, 미적용 (amt)

<td> <input type="number" name="amt" value="${m.amt}"> </td> 

2, 적용 (pprice, pdeliFee)

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

<td> <input type="hidden" name="pprice" value="${m.pprice}"> 
	<fmt:formatNumber value="${m.pprice}" type="number" groupingUsed="true"/> </td>	
	
	<td> <input type="hidden" name="pdeliFee" value="${m.pdeliFee}"> 
	<fmt:formatNumber value="${m.pdeliFee}" type="number" groupingUsed="true"/> </td> 

결과:
