大家好，我是雄雄，上期我们解决了个bug，详情点击这里：[**我去，终于解决了**][Link 1] ，今天，我们来看看【如何在idea中使用jstl标签库】

前言：

像myeclipse和eclipse这种编辑器，jstl标签库系统插件里面直接就有，但是当我们使用idea想使用jstl标签库时，就不支持了，那如果想在idea中使用jstl标签库，我们应该怎么做呢？

1.在网上下载jstl的jakarta-taglibs-standard-1.1.2.zip，下载地址：https://download.csdn.net/download/qq\_34137397/14503697，也可以自行去网上找下载地址。解压出来，找到lib，里面只有两个jar包，都拿着，放在项目的lib下面，如图所示：

2.只有这一步还是不可以的，接下来我们还需要加入tld文件，好让idea识别jstl的标签，添加方法如下：

点击File—》Setting—》languages&Frameworks—》Schemas and DTDs—》点击右边的+号，在Url中写http://java.sun.com/jsp/jstl/core，在下面的File输入框后面的三个点（…）处选择下载文件的tld文件（tld/c.tld）,点击OK即可使用，所有操作如下图所示：

最后一定要记得在页面中加入：

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

下面就是使用示例：

<c:forEach items="empList" var="emp">
          <tr>
              <td>${emp.eid}</td>
              <td>${emp.ename}</td>
              <td>${emp.epass}</td>
              <td>${emp.edid}</td>
          </tr>
      </c:forEach>
