同学你好，这个可能会和jstl的依赖版本有关，如果同学不想在lib中引入，建议在pom文件中引入这两个坐标试试：

<!-- https://mvnrepository.com/artifact/org.apache.taglibs/taglibs-standard-impl -->
<dependency>
    <groupId>org.apache.taglibs</groupId>
    <artifactId>taglibs-standard-impl</artifactId>
    <version>1.2.5</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.taglibs/taglibs-standard-spec -->
<dependency>
    <groupId>org.apache.taglibs</groupId>
    <artifactId>taglibs-standard-spec</artifactId>
    <version>1.2.5</version>
</dependency>

如果我的回答解决了你的疑惑，请采纳！祝学习愉快！

我把之前学JSTL的两个JAR包放到lib里面了

这样倒是可以运行

我看源码里面的pom.xml跟这一节的jstl的也不一样啊
