Я разрабатываю пример Spring MVC + AngularJS + JPA. В этом примере я хотел, чтобы пользователь регистрировался, теперь, когда я нажимаю ссылку на регистрацию, я вижу следующую ошибку: не уверен, что происходит неправильно?org.springframework.beans.NotReadablePropertyException: Invalid property 'userName' класса bean: свойство bean 'userName' не читается или имеет
Ошибка Я вижу ниже:
org.springframework.beans.NotReadablePropertyException: Invalid property 'userName' of bean class [com.sivalabs.angularcrud.entities.User]: Bean property 'userName' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
