错误如下:org.apache.jasper.JasperException:绝对 uri:http://java.sun.com/jsp/jSTL/core 无法在 web.xml 或 jar 文件中解析与此应用程序一起部署
我尝试了这篇文章How to install JSTL? The absolute uri: http://java.sun.com/jstl/core cannot be resolved但没有任何作用:

我没有看到任何使用 Maven 解决该问题的方法，我不想在 webapps 库中手动使用 JAR。
请您参考如下方法:
将以下依赖项添加到 pom.xml
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
</dependency>
在jsp中导入以下uri。
<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c" %>
OR
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
