Spring boot - return user object after log in

Question

I have a spring boot application with WebSecurityConfigurerAdapter configured like this -

http.csrf().disable()
                    .exceptionHandling()
                


        

Answer 1

In the accepted answer you need two calls to get the data you want. Simply return the data after the login in a custom AjaxAuthenticationSuccessHandler like this.

@Bean
public AjaxAuthenticationSuccessHandler ajaxAuthenticationSuccessHandler() {
    return new AjaxAuthenticationSuccessHandler() {

        @Override
        public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
            response.getWriter().write(new ObjectMapper().writeValueAsString(new UserAuthenticationResponse(authentication.getName(), 123l)));
            response.setStatus(200);
        }

    };
}

and register the successhandler:

http.successHandler(ajaxAuthenticationSuccessHandler())
