换电脑了，然后把以前的项目弄到新电脑里，结果所有的jsp就都出这么个问题，以前可以用的不知道是什么原因，可能是eclipse？以前用的eclipse是Mars版本的，现在是官网下的最新版oxygen。网上说缺少standard.jar，但是如果jstl版本是1.2的就不需要这个jar，正巧我的maven配的jstl-1.2的，也确认已经下载了jar，但是还是报这个错，百思不得其解。然后尝试换成jstl-1.1对应的uri值和jstl-1.0对应的uri值，还是不行，后来抱着死马当活马医的心态在pom.xml中添加了：

<dependency>
	<groupId>taglibs</groupId>
	<artifactId>standard</artifactId>
	<version>1.1.2</version>
</dependency>

添加了standard.jar后，所有的jsp页面都不报错了，现实真是太讽刺了！！！

以上是我的解决办法，但是问题的原因我还是不知道，为什么以前在eclipse-mars版本跑就ok，现在在eclipse-oxygen就不行，不过也可能是换了新的maven的问题？以前是maven-3.5.0，现在是maven-3.5.2，按理说不是大版本的更新不会差这么多吧？

有知道的小伙伴请给我留言！谢谢！

Craft.js

Great React framework that helps you create user-friendly page editors. It makes it possible to change the content of a web page using drag & drop, detailed text controls, media embeds, and more. Perfect for building content management systems and WYSIWYG apps.

<%@ taglib prefix=

<%@ taglib prefix="c" uri="http://java.sun.com/jst

有些时候，<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>会报错，错误提示为：
Can not find the tag library descriptor for "http://java.sun.com/jsp/jstl/core"
主要原因是缺少
jstl.jar
standard.jar

两个Jar包

在pom.xml增加：

<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.1.2</version>
</dependency>
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>1.1.2</version>
</dependency>

如果还不行，请调整jstl.jar 版本，这个主要根据web的version的版本有关。增加如下

<jsp-config>
        <taglib>
            <taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
            <taglib-location>/WEB-INF/tlds/fmt.tld</taglib-location>
        </taglib>
        <taglib>
            <taglib-uri>http://java.sun.com/jstl/fmt-rt</taglib-uri>
            <taglib-location>/WEB-INF/tlds/fmt-rt.tld</taglib-location>
        </taglib>

        <taglib>
