Пишу веб приложение на Spring Boot+Thymeleaf+Spring Security+MySQL. После создания post метода в контроллере, перестала открываться страница с полями для ввода.
Есть страница, в которой есть поля для ввода. По клику на кнопку данные из полей должны сохраниться в базе данных.
Сейчас же я не могу даже пройти по http запросу к этим полям и получаю две ошибки:
Neither BindingResult nor plain target object for bean name 'patient' available as request attribute
и
thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/user/profile.html]")
Как можно исправить эти ошибки?Класс модели:import lombok.AllArgsConstructor;
