IDEA:Error running Tomcat Server: server.xml does not contain virtual host 'localhost'.

IDEA中配置tomcat，启动项目出现该错误：Error running Tomcat Server: server.xml does not contain virtual host 'localhost'.

本人解决方法如下：

1.配置好idea的application servers

file-->setting 搜索application servers

2.找到Tomcat目录下的server.xml文件

找到server.xml文件中的标签，修改name属性为:localhost

3.如果启动还是报：Error running Tomcat Server: server.xml does not contain virtual host 'localhost'.

修改hosts文件：windows操作系统路径如下：C:\Windows\System32\drivers\etc

打开host文件夹：添加属性

127.0.0.1 localhost
