在配置servlet不同路径时遇上以下两个错误:

java.lang.nosuchmethoderror: javax.servlet.servletcontext.getvirtualservername()ljava/lang/string；  java.lang.classnotfoundexception: org.apache.jsp.index_jsp； 。

对于第一个问题，我上网查阅了很多资料后发现，可能是tomcat版本冲突导致，catalina log如下:

我先试着删除其他tomcat版本，重新配置tomcat环境变量并重新部署tomcat。发现并没有解决问题，再次上网查阅，发现getcontextpath()在servlet2.5特有。于是试着删除原先jar包中的servlet-api.jar,然后重新部署项目。发现了第二个问题，log如下:

再次查阅资料，发现是缺少jar包。因为jdk1.8的扩展jar包里没有servlet相关api，故idea会导入失败.

此时需要导入jar包，之前我是下载相关api 。

然后放到下图目录中 。

为了防止出现缺少jar包问题，建议直接去tomcat目录下的lib中找到servlet-api.jar，直接复制到ext中。然后再重新部署一下tomcat，问题解决.

总结 。
