Ag Service

register(user:AuthSignUp): Observable<any> {
return this.http.post(AUTH_API + 'signup', {
  cin: user.cin,
  delegation: user.delegation,
}, httpOptions);
}

Login Component

this.authService.register
      (new AuthSignUp(this.cin,this.delegation)).subscribe(
        response  => {
          console.log(response )
          this.password=response ;
          this.signUpSuccessful = true;
          this.isSignUpFailed = false;
        },
        err => {
          this.errorMessage = err.error.message;
          this.isSignUpFailed = true;
        }
      );

Answer 1

In MessageResponse class you can add a new property named data

@Getter
@Setter
class MessageResponse<T> implements Serializable{
   private String message;
   private T data;

   public MessageResponse(String message,T data){
      this.data=data;
      this.message=message;
   }

   public MessageResponse(String message){
      this.message=message;
   }

}

Now, you can pass data as any type of object since MessageResponse is a generic class . In this case this data will be String

return ResponseEntity.ok(new MessageResponse<String>("User registered successfully!",PASSWORD WILL BE HERE));

In ui part, you can read it from property

this.password=response.data
