mavan(迭代器报错)

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

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>
