Add external resources folder to Spring Boot

Question

I\'d like to add a resource folder relative to the location of the jar (in addition to packaged resources within my jar), for example:

/Directory
    Applica         


        

Answer 1

Your second approach would work:

@Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**")
            .addResourceLocations("/resources/", "file:resources/");
}

but only if you launched Spring Boot from /Directory, because file:resources/ is a relative path.

cd Directory
java -jar Application.jar

It's nice if you can pack everything into the jar, but if you have to reference external resources, you should use absolute paths to avoid problems like this.
