java – JSP字符串格式截断

有没有人知道如何使用标签库在JSP中截断字符串？我要使用 Jakarta Taglibs,但是说它已经退休,因为：

With the advent of JSTL,the core features of many of the libraries had been standardized and the need for these libraries diminished. As such,much of the Taglibs codebase moved into maintenance mode.

解决方法

您可以使用 JSTL substring function：

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

${fn:substring(myVariable,5)}
