I have this @Bean redirecting requests to my Spring Boot backend.

@Bean

WebMvcConfigurer configurer () {

    return new WebMvcConfigurerAdapter() {

        @Override

        public void addResourceHandlers (ResourceHandlerRegistry registry) {

            registry.addResourceHandler("/data/static/images/**")

                    .addResourceLocations("file:" + System.getProperty("user.dir") + "/static/img/");

        }

    };

}

It works perfectly for URLs such as:

http://localhost:4200/data/static/images/champion/tiles/Ahri_0.jpg

But not for URLs such as:

http://localhost:4200/data/static/images/champion/tiles/Tahm%20Kench_0.jpg

The image is correctly shown in my Angular2 front end if the champion name does not contain any of: space, ampersand or single quote characters.

I ran a trace level logging debug and made both types of requests -- one with and without a "bad" character. Currently, it seems as if the backend searches for the correct file. However, it turns out that it claims it can't find it. I quintuple checked the file in my insanity, I know it is there and that the path printed is correct.

Here is an example log message:

EDIT: I've implemented the class in the accepted answer, and it's definitely working because I printed the resource name (after encoding the characters I had trouble with.) However, the result is still a 404 error.

Log is below. The champion/Aatrox2Epng bit is due to a println statement in the method @slimane posted below.

another EDIT -- sorry for the confusion, I changed the path because I thought paths with periods would work now.

@Bean

WebMvcConfigurer configurer () {

    return new WebMvcConfigurerAdapter() {

        @Override

        public void addResourceHandlers (ResourceHandlerRegistry registry) {

            registry.addResourceHandler("/data/static/images/**")

                    .addResourceLocations("file:" + System.getProperty("user.dir") + "/static/8.23.1/img")

                    .resourceChain(true)

                    .addResolver(encodedPathResourceResolver());

        }

    };

}

define your own PathResourceResolver as below:

import org.springframework.core.io.Resource;

import org.springframework.web.servlet.resource.PathResourceResolver;

import org.springframework.web.servlet.resource.ResourceResolver;

import java.io.IOException;



public class CustomPathResourceResolver extends PathResourceResolver implements ResourceResolver {



    @Override

    protected Resource getResource(String resourcePath, Resource location) throws IOException {

        //fixes problems with whitespaces in url

        resourcePath = resourcePath.replace(" ","%20");

        return super.getResource(resourcePath, location);

    }

}

and then register it in your configuration:

@Override

    public void addResourceHandlers(ResourceHandlerRegistry registry) {



        registry.addResourceHandler("/data/static/images/**")

                .addResourceLocations("file:" + System.getProperty("user.dir") + "/static/img/")

                .resourceChain(true)

                .addResolver(new CustomPathResourceResolver())

                ;

    }
