springboot 定制错误页面

项目中经常遇到的异常情况

• 400-Bad Request
• 401-Unauthorized

  If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials.

• 403-Forbidden

  The server understood the request, but is refusing to fulfill it.

• 404-Resource not found
• 500-Internal Server Error

定制错误页面的方法

1. 在src/main/resource/templates/error/目录中增加
2. 在src/main/resource/public/error/目录中增加

其中第一种方式的优先级大于第二种。
