Cache configuration not working correctly

[sbrunecker]

Overview of the issue

I am using jhipster-sample-app-gradle and started it with Spring profile prod. Most files are served with Cache-Control: no-store. It seems the only file where the cache configuration is working is i18n/en.json which is served with Cache-Control: max-age=126230400, public.

So I believe the issue is:

• content of subfolders of static/content is not cached
• the Angular application is not compiled to static/app anymore but directly to static/ while the cache configuration in StaticResourcesWebConfiguration still configures a policy for classpath:/static/app/

Motivation for or Use Case

Caching makes the application more performant.

Reproduce the error

1. Clone jhipster-sample-app-gradle
2. Start the database from src/main/docker/mysql.yml or configure h2 to start with prod profile
3. Start the application with prod profile
4. Go to http://localhost:8080/ and observe that only en.json is configured to be cached

Suggest a Fix

With the following configuration more files have a cache control header set. However, this will also cache service-worker.js and I'm not sure if it's okay.

registry.addResourceHandler("/content/**", "/i18n/*")
    .addResourceLocations("classpath:/static/content/", "classpath:/static/i18n/")
    .setCacheControl(getCacheControl());
registry.addResourceHandler("/*.js")
    .addResourceLocations("classpath:/static/")
    .setCacheControl(getCacheControl());
