1. SpringBoot 404, 500 error prompt page
1. When using the ThymeLeaf template, springBoot will automatically
src/main/resources/templates/error/
Find the error page of 404.htm and 500.html in the folder
The naming rule of the error prompt page is: error code.html, such as 404 is 404.html, 500 is 500.html
2. If the ThymeLeaf template is not used, SpringBoot will go to the static resource folder to find the error prompt pages of 404.htm and 500.html, named the same as above.
SpringBoot's default static resource files are:
/static
This is directly generated by the SpringBoot project.
There are also 3 hidden static resource folders:
/resources /public /METAINF/resources/
That is, there are 4 default static resource paths in Springboot, which are:
classpath:/METAINF/resources/，
classpath:/resources/，
classpath:/static/，
classpath:/public/
The priority order is: META-INF/resources > resources > static > public
You can modify the default mapping** by modifying the spring.mvc.static-path-pattern property in the application.properties file. The configuration is as follows:
spring.mvc.static-path-pattern=/** spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,classpath:/myfile/
二、SpringBoot 4xx.html、5xx.html错误提示页面
错误代码的类型很多，如400、403、404等等，如果按照上面的方法，需要添加很多页面而
SpringBoot提供了通用的命名方式，就是使用4xx.html、5xx.html命名，如：
4xx.html表示能匹配到400、403、404……等错误
5xx.html表示能匹配到500、501、502……等错误
如果404.html和4xx.html同时存在时，优先使用最匹配的，即当发生404错误时，优先匹配404.html页面
