Spring boot + Angular routing with parameter problem

Question

I am trying to write a simple UI service that's built upon Eureka Client, Ribbon Client, Spring Boot and Angular. I have a simple front in angular that has the following routing:

const routes: Routes = [
{ path: 'home', component: HomeComponent },
{ path: 'course/:id', component: DetailedCourseComponent },
{ path: 'coursefix', component: DetailedCourseComponent }, // I did this one to test the parameter issue.

{ path: '', redirectTo: '/home', pathMatch: 'full' },
];

And this specific course component:

DetailedCourseComponent.html

<p>detailed-course works!</p>

as you can see, I'm not too interested in the id parameter for the moment but I will use it eventually.

Whenever I test running the url for course/1 with angular on localhost through the CLI console (No spring boost, eureka, ribbon, etc) it works correctly showing the following message: "detailed-course works!"

Now whenever I compile the front into the "resources/static" folder with angular CLI and run the website from IntelijIdea it fails to access the url: "course/1" with an empty white screen. Although, if I enter the url /coursefix (Without any parameters) I get the "detailed-course works!" any idea of what can be causing this url parameter issue? I tried googling a lot but found no luck so far.

To clarify: Routing works correctly (When deployed with Spring boost), redirection also works once I enter the URL: http://localhost:9092/ => http://localhost:9092/home/

Just in case, this is my angular.json file

When Angular is built, it creates a problem with URL and routing reference, you can only navigate if you access localhost -> url1 -> url2. If you try to go straight to url2, it doesn't work.

To answer this problem you need to add a LocationHashStrategy (that's how I managed to fix it). This adds a # in the URL, in case you don't like it, it doesn't help (i.e. localhost/#/home)

app-routing.module.ts:

...
RouterModule.forRoot(routes, {useHash: true})
...

try to add this to the app.module

import { LocationStrategy, PathLocationStrategy } from '@angular/common';

providers: [
    {
        provide: LocationStrategy,
        useClass: PathLocationStrategy
    }
]
