在IDEA上，JATL标签库的jar包已经导入

![image-20210516201902962][]

但是成功部署之后，跳转页面会一直加载，不显示内容

# 解决办法 #

官网下载地址：[http://archive.apache.org/dist/jakarta/taglibs/standard/binaries/][http_archive.apache.org_dist_jakarta_taglibs_standard_binaries]

将【taglibs-standard-impl.jar】下META-INF目录下需要引入的 tld 文件复制到 WEB-INF 目录下。

将需要的tld 文件复制到 WEB-INF 目录下之后重新部署即可解决
