我的这个问题是，idea运行时，在自带的tomcat目录下没找到servlet-api.jar这个包 和 jdk目录下，也没有找到这个包。

解决方法。就是导入servlet-api.jar并在 jdk目录下粘帖一份。

解决方法：

我先去**tomcat**[官网](https://tomcat.apache.org/)下载了 **tomcat**    然后解压到硬盘。

1.开始导入：

找到你解压 tomcat的目录，然后选中lib目录下servlet-api.jar

然后重新运行。发现还有一个jdk目录下的servlet-api.jar 也是没有找到

2.把****servlet-api.jar复制一份，****jdk目录下：

最后问题解决：
