这篇文章主要介绍了解决IDEA配置tomcat启动报错问题,本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下 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： 19-Feb-2018 08:26:44.175 信息 [main]

java.lang.Thread.run(Thread.java:748) 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 到此这篇关于解决IDEA配置tomcat启动报错问题的文章就介绍到这了 |
