1 : 代码配置静态资源路径
2 : 登录拦截器
3 : 配置错误页面和所有跳转页面

如果设置了 项目contextPath

server.servlet.context-path=/apply
项目访问路径为:http:127.0.0.1:8080/apply

绝对路径引入：
<link rel="stylesheet" href="/apply/css/index/base.css" />
相对路径引入：（最前面不要加’/‘ ）
<link rel="stylesheet" href="css/index/base.css" />

所有路径最好使用相对路径（前面不要加‘/’）、不管是引入资源还是跳转后台
这样不用担心 项目的contextPath 修改、不然当contextPath修改 所有的路径都要修改（包括请求后台的路径）

不设置ContextPath

-#server.servlet.context-path=/apply
项目访问路径为:http:127.0.0.1:8080/ 直接就是‘/’
