异常报错处理:
The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
迭代器需求:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!-- JSTL -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<!-- JSTL实现包 -->
<dependency>
<groupId>org.apache.taglibs</groupId>
<artifactId>taglibs-standard-impl</artifactId>
<version>1.2.5</version>
</dependency>
解压实现包“taglibs-standard-impl-1.2.5.jar”，在META-INF拿一个tld文件，其实一个就够用了
image.png
然后web.xml里配置jsp-config
<jsp-config>
<!-- 配置c描述文件-对应c标签，这里的taglib-uri对应jsp中引入的uri -->
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/lib/c.tld</taglib-location>
</taglib>
</jsp-config>
