针对Maven项目 Cannot resolve taglib with uri …
jsp问题描述
在jsp页面中引入标签库时 错误提示： Cannot resolve taglib with uri http://java.sun.com/jsp/jstl/cor Cannot resolve taglib with uri http://java.sun.com/jsp/jstl/fmt
源码如下：
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
运行时访问页面提示的错误
如果是使用了直接引用标签如： <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 则可能提示类似如下错误
HTTP Status 500 – Internal Server Error

解决办法
在pom.xml文件中引入如下依赖。=可能还有其他版本，版本自己斟酌=
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>1.1.2</version>
</dependency>
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.1.2</version>
</dependency>
解决后截图如下：
