I am trying to implement forgotPasswordPage.I am sending verification email to user.If user clicks link,then rest function is called.If operation is successfull I need to redirect Angular Password change page.
How will be redirection, how can I call angular page from java spring boot rest. It is possible for jsp but In angular I can not find.”redirect” and “forward” does not work in project.Returns string.Do you have any ideas.Thanks for your answer.
