Seems like a classpath issue. Make sure there isn't a servlet.jar in the classpath other than the one already included in Tomcat_HOME/lib
似乎是类路径问题。确保没有servlet。除了在Tomcat_HOME/lib中已经包含的以外，在类路径中的jar。

Write localhost:yourportnumber on your web browser. Is your Tomcat server working? If Tomcat server is not working on your web browser, you could not load Tomcat server correctly, try again and click startup.bat under the C:\tomcat\bin.
在web浏览器上写入localhost:yourportnumber。您的Tomcat服务器是否正常工作?如果Tomcat服务器没有在web浏览器上工作，您无法正确地加载Tomcat服务器，请再次尝试并单击startup。蝙蝠在C:\ tomcat \ bin。
If Tomcat server is working correctly, put Tomcat folder on C:/Tomcat. And show classpath (Tomcat installation directory) on your IDE.
如果Tomcat服务器工作正常，请将Tomcat文件夹放在C:/Tomcat上。并在IDE上显示classpath (Tomcat安装目录)。
