通路JSP頁面報錯According to TLD or attribute directive in tag file, attribute value does not accept

通路JSP頁面jstl表達式使用錯誤，詳細錯誤如下：

出現上述錯誤的原因是，在JSP頁面使用了fmt标簽庫

原因：

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>
//使用了日期格式化方法
<fmt:formatDate pattern="yyyy-MM-dd" value="${user.birthday}" />
           

出現錯誤的原因是使用的是jstl1.2,在jstl1.0和jstp1.1、jstl1.2版本在使用标簽庫的時候存在一定的差别，在jstl1.0以後的版本uri都應該加上/jsp,引用方法如下：

解決方法一：（推薦）

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
//使用了日期格式化方法
<fmt:formatDate pattern="yyyy-MM-dd" value="${user.birthday}" />
           

解決方法二：

修改web.xml和jstl庫版本

//修改2.3以上版本為2.3及以下版本版本
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         id="myweb" version="3.0">
