新建项目的话看下面的链接，这里我只列出我遇到的一些问题。
结构目录如下： 
1、启动 Java Web 项目，打开“Project Structure”，配置“Facets”和“Artifacts” 
2、运行tomcat可以访问localhost:8080,访问http://localhost:8080/student/getAllStudent报
HTTP Status 500 - 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 
以前tomcat启动的时候扫描包太多，修改了启动配置文件：找到 tomcat/conf/catalina.properties
tomcat.util.scan.DefaultJarScanner.jarsToSkip=*.jar
修改这个为
tomcat.util.scan.DefaultJarScanner.jarsToSkip=
或者默认配置：
tomcat.util.scan.DefaultJarScanner.jarsToSkip=\
bootstrap.jar,commons-daemon.jar,tomcat-juli.jar,\
annotations-api.jar,el-api.jar,jsp-api.jar,servlet-api.jar,websocket-api.jar,\
catalina.jar,catalina-ant.jar,catalina-ha.jar,catalina-tribes.jar,\

重启tomcat就ok了。
