1、/login

.and().formLogin().loginPage("/user/login.html")

                //在successHandler中，使用response返回登录成功的json即可，切记不可以使用defaultSuccessUrl，defaultSuccessUrl是只登录成功后重定向的页面，failureHandler也是由于相同的原因不使用failureUrl。
                .loginProcessingUrl("/login").successHandler(
                        new AuthenticationSuccessHandler(){

                                httpServletResponse.setContentType("application/json;charset=utf-8");

                                out.close();
