The static directory of the spring boot program is in the resources / static directory by default. When it is packaged as jar, the static directory will be packaged. There will be some problems:

Looking at the official documents, you can find that static can actually be external.

Method 1: modify the configuration file directly

spring.resources.static-locations=file:///E://resources/static

Custom configuration method

@Configuration
public class StaticResourceConfiguration extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations("file:/path/to/my/drop@R_229_2419@/");
    }
}

Recommended method 1 is safe and harmless
