EL工作，但JSTL没有，使用Spring MVC

时间：2015-11-13 19:01:58

标签： java spring jsp jstl el

我已经在这上面待了几个小时但仍然无法弄明白！搜索了JSTL上的所有相关主题，但没有运气。

我的网站使用的是Spring 3.1，JSTL曾经用过，但是在我切换到新的comp并重新设置环境后，它并没有。我不知道缺少什么！

有趣的是，当我做一个简单的<c:out value="${topWorks}"/>时，它返回错误＆＃34; Servlet.service（）for servlet jsp引发了异常 org.apache.jasper.JasperException：/user/indexx.jsp（第176行，第5列）无标记＆＃34; out＆＃34;在使用前缀＆＃34; c＆＃34;＆＃34;

导入的标记库中定义

但我的EL正在工作，因为所有的javascript和css都已加载，因为我使用

<script src="${pageContext.request.contextPath}/js/bootstrap.min.js"></script>

以下是我所拥有的：

  1. 在JSP页面<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

    2. 之上

  2. web.xml是3.0 

    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

  3. Servlet有jstlview 

    <bean id="jstlViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/"/>
<property name="suffix" value=".jsp"/>

    4. 4.POM文件，包括jstl libs（我也尝试按照stackExchange＆＃39; JSTL信息页面的建议删除jstl-1.2，但也没有工作）

也许你的taglib错了，在你的jsp文件中试试这个：

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

答案 1 :(得分：0)

在摆弄了一段时间后，我设法解决了它，仍然使用我们网站建议的方法。但是我发现我有一个名为tag的额外文件夹，里面有一些自定义标签，删除了那些，并删除了POM中所有与jstl相关的库。它起作用了......
