How to serve static resource in springboot having custom path from Controller?

Question

I have this resource handler, and I am able to call the static web page located in different location, but I am trying to call from controller class I am not able to get the page

@Configuration
public class Static_ResourceHandler implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/system/files/**").addResourceLocations("file:/home/niteshb/Documents/data");
    }
}

This is what I am calling

http://localhost:8080/system/files/test.html

but how to call it from controller, I was trying something like this but its not working This is my controller class call..

    @GetMapping("/")
    public String getfile() {
        return "test.html";
    }

Answer 1

Create a Get mapping for /system/files/ , for which you had created the resource handler, and return the file in the newly created method.

@GetMapping("/system/files/")
public String getStaticfile() {
    return "/system/files/test.html";
}

Hope that should work.
