Methods to access static resources in SpringBoot

1. Overview

springboot’s default static resource access path is: /static or /public or /resources or /META-INF/resources Such addresses are required It is defined in the src/main/resources directory file, so that the static address directory of the project can be automatically loaded into the classpath when the project is started. The static access address is actually loaded into the WebMvcConfigurerAdapter using the ResourceHttpRequestHandler core processor to override the addResourceHandlers method. Redefine the static access directory. We can also implement the method, manually specify the static access path and inherit the WebMvcConfigurerAdapter and rewrite the internal method addResourceHandlers to achieve the effect we want.

The first way: Place it in the src/main/webapp directory

Static resources placed in the webapp directory can be accessed directly

The second way: put it under the classpath

Instructions in ResourceProperties

org.springframework.boot.autoconfigure.web.ResourceProperties
 private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
   "classpath:/META-INF/resources/", "classpath:/resources/",
   "classpath:/static/", "classpath:/public/" };

Static resources are placed under the classpath by default: Defaults to classpath:[/META-INF/resources/,/resources/, /static/, /public/] plus context:/ (the root of the servlet context).
