How to format string using MessageFormat in JSTL

A string is got from ENV variable by the following codes:

<span><%=(String)System.getenv("NEW_COPYRIGHT")%></span>

The ENV variable is like Copyright &copy; {0} XXX.

How to replace {0} with the current year and display Copyright © 2018 XXX in the jsp file?

Thanks

There is no standard jstl tag to do this.We can use other way to do it.

a. Use fn:replace to do it:

<c:set var="env" value="Copyright &copy; {0} XXX"/>
<c:out value="${fn:repalce(env,'{0}','2018')}"/> <!-- the year can also be access via a variable -->

b. Define your own custom tag to format it using java.text.MessageFormat,more details can be found at Understanding and Creating Custom JSP Tags
