jstl的taglibs导入出现问题

已经在maven中添加了jstl的依赖，

但是报错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

同学你好，建议同学点击File ->Project Structure，在modules中，查看sm_web下是否有jstl，如:

如果没有，建议点击右上角的“+"，选择Modeled Dependency，找到jstl并点击ok，

然后重启项目再试试。

祝：学习愉快~

Module下有这个jar包，target目录下的WEB-INF/lib包下也有jstl.jar，真个报错如下： 14-Feb-2020 20:33:43.789 信息 [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deployment of web application directory D:\apache-tomcat-8.5.13\webapps\ROOT has finished in 29 ms 14-Feb-2020 20:33:43.789 信息 [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deploying web application directory D:\apache-tomcat-8.5.13\webapps\sm_web_war 14-Feb-2020 20:33:44.286 详细 [localhost-startStop-1] org.apache.jasper.servlet.TldScanner.scanResourcePaths No TLD files were found in resource path [/WEB-INF/]. 14-Feb-2020 20:33:44.290 信息 [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deployment of web application directory D:\apache-tomcat-8.5.13\webapps\sm_web_war has finished in 500 ms java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at Caused by: org.apache.jasper.JasperException: 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

同学你好，建议同学去本地仓库中，找到jstl的文件删除，重新导入jstl，删除target文件，重启项目再试试。祝：学习愉快~
