<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>接着可以在页面上使用,如core标签:
<c:out value=“${expression}” default=“a”/> <c:set var=“str” value=“试下” scope=“session”></c:set>//设置某个范围如session属性的值 <c:set target=“bean实例” property=“” value=“”/>//设置某个bean成员变量的值 等同于 <jsp:setProperty property=“” value=“”/> <c:remove var=“” scope=“”/>//移除某个范围的变量要运行JSTL标签,需要jstl1.2.jar包
<c:import url="http://www.url.com/edit.js" var="newsfeed"/>将请求重新定向到http://www.yourname.com/login.jsp页,相当于response.setRedirect();
<c:redirect url="http://www.yourname.com/login.jsp"/>
<c:redirect url="login.jsp"><c:param name="id" value="888"/></c:redirect>将参数888以id为名字传递到login.jsp页面,相当于login.jsp?id=888
