@ Исключенное исключение возврата в UserDetails в Spring-security

Question

Пожалуйста, покажите мне, где у меня проблема? Вот мой проект: https://github.com/intrade/inventory Я пытаюсь включить Весна безопасности с помощью Java конфигурации и когда я пытаюсь придать зависимость типа MyCustomUserDetailsService в my SecurityConfig class я получаю исключение:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.springapp.mvc.services.MyCustomUserDetailsService com.springapp.mvc.InitApp.SecurityConfig.myCustomUserDetailsService; nested exception is java.lang.IllegalArgumentException: Can not set com.springapp.mvc.services.MyCustomUserDetailsService field com.springapp.mvc.InitApp.SecurityConfig.myCustomUserDetailsService to com.sun.proxy.$Proxy38

Спасибо заранее!

Answer 1

Вы пытаетесь авторизовать свою службу пользовательских данных по классам, но это не сработает, потому что весенний боб - это фактически прокси, созданный вокруг этого класса (а не экземпляр класса). Однако прокси-сервер будет реализовывать все интерфейсы исходного компонента, поэтому инжекция по интерфейсу безопасна.

Обмен эта линия:

@Autowired 
private MyCustomUserDetailsService myCustomUserDetailsService; 

для этого:

@Autowired 
private UserDetailsService myCustomUserDetailsService; 

Прочитайте раздел Proxying Mechanisms в Spring AOP, чтобы понять детали.
