Solution: Add @CrossOrigin("*") annotation on top of respective Controller Class.

By using CrossOrigin("*") your accepting all domains.

which is not recommended and here is why .

Using @CrossOrigin(origins = "http://localhost:4200")

will have the same effect for your situation and would only accept localhost:4200 .

The best solution is to configure Angular to proxying call to the backend.

Take a look at Angular’s Proxing documentation
