Possible to comment-out JSTL code?

问题:

If you want to temporarily comment-out a piece of JSTL code that you may re-enable later, is this possible?

Would this work?

<!--<c:out value="${someVar}"/>-->

回答1:

When you write such comment in your JSP file:

<!-- <c:out value="${someVar}"/> -->

This means that this comment will be outputed, i.e. present in the generated HTML page. If you want to hide your code, use the JSP comments:

<%-- <c:out value="${someVar}"/> --%>

回答2:

<%-- <c:out value="${someVar}"/> --%>

This way, none of jstl code inside will be executed.
