При попытке подключить Spring Security по следующему коду https://github.com/proselytear/SpringSecurityApp проявилась 3 ошибки:

User.java (брал изначально из https://github.com/rainningToSnow/springMVC-mybatis-postgresql, потом внес некоторые правки, попытавшись добавить связь с ролями; только с users в изначальном варианте работало):
