En el código del primer post:

Código Java:

.header("Access-Control-Allow-Headers: 'application/json'",
        "origin, content-type, accept, authorization")
 

creo que debería ser:

Código Java:

.header("Access-Control-Allow-Headers",
        "origin, content-type, accept, authorization")
 

Gracias por la respuesta, acabo de probar eso y sigue sin funcionar :( da el mismo error de CORS

Código:

Access to XMLHttpRequest at 'http://192.168.38.7:8080/rest2/webresources/login' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
core.js:6014 ERROR

Código:
