TOMCAT 修改错误页404,400,500 的设置

1.找到web.xml
如果只想修改tomcat的，就打开root目录下conf的web.xml
如果是运行的某个项目的，就打开webapp下的那个项目的web-inf文件夹下的web.xml
在/web-app上加如下内容

         400
         /error.html
     
 
     
         404
         /error.html
     
     
         500
         /error.html
     

2.在wepapp文件夹中的 项目文件夹下
加error.html文件
