推荐答案

JSTL库似乎丢失了

1)请添加jstl jar，这是下载链接 链接

1) please add jstl jar here is link to download Link

，如果您正在使用Maven项目

and if you are using maven project

2)在pom.xml中添加依赖项

2)add dependency in pom.xml

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>jstl</artifactId>
  <version>1.2</version>
</dependency>
