Idea启动项目没报错页面却显示404
1.拿到一个比较旧的项目来跑，换了环境
jdk:1.6.0_45
tomcat:6.0.39
2.启动出现以下情况
D:\apache-tomcat-6.0.39\bin\catalina.bat run
Using CATALINA_BASE: "C:\Users\阿汐\.IntelliJIdea2019.3\system\tomcat\Unnamed_Wifi_Portal_Mgr"

跳出页面如下：
3.尝试在tomcat安装目录下去跑项目可以成功！
4.偶然发现日志里的Using CATALINA_BASE: “C:\Users\阿汐.IntelliJIdea2019.3\system\tomcat\Unnamed_Wifi_Portal_Mgr”，可能是先用了系统中的CATALINA_BASE来运行项目。
5.重新配置tomcat启动，添加如下环境变量，定位到使用的tomcat环境
6.重启成功
**后记：*日志信息里有些地方还是会爆红，不知道是不是哪里有错，现在可以正常启动运行，那个就等后面再看看。
