Я пытаюсь создать базовые операции CRUD, используя JSF 2.2, Spring 4.01 и Hibernate. В файле register.xhtml, если я нажму кнопку регистрации, она должна сохранить firstname (на данный момент) в базе данных.
У меня есть следующее:
- Страница регистрации (
register.xhtml)
RegistrationAction (контроллер) RegistrationEntity (класс сущностей, который имеет только одно поле, firstName, на данный момент) LoginRegistrationServiceImpl (класс обслуживания) - это реализует интерфейс LoginRegistrationService
При развертывании я получаю следующее исключение:
com.sun.faces.mgbean.ManagedBeanCreationException: Cant instantiate class: Controllers.RegistrationAction.
Caused by: org.springframework.beans.factory.BeanCreationException: Injection of autowired dependencies failed for class [class Controllers.RegistrationAction]
Я попробовал следующие изменения.
<context:component-scan base-package />- Я отдельно создал так:
<bean id="lrInterface" class="Serviceimplementations.LoginRegistrationSerImpl"/>
- Я использовал
@Configuration и @ComponentScan("Serviceimplementations") вместо объявления в файле конфигурации.
- Изначально я использовал
@ManagedBean и @Controller в RegistrationAction. После этого я изменил на SpringBeanAutowiringSupport.
Примечание: у меня нет параметризованного конструктора. Я искал много соответствующих тем, и это может быть глупой ошибкой, но я все еще не знаю, как ее решить.
RegistrationAction.java:
@ManagedBean(name="register")
@Configuration
@ComponentScan("Serviceimplementations")
public class RegistrationAction extends SpringBeanAutowiringSupport implements Serializable {
private LoginRegistrationSerImpl lrInterfcae;
public LoginRegistrationSerImpl getLrInterfcae() {
return lrInterfcae;
}
@Autowired
public void setLrInterfcae(LoginRegistrationSerImpl lrInterfcae) {
this.lrInterfcae = lrInterfcae;
System.out.println("Interface Obj--" + lrInterfcae);
}
}
LoginRegistrationImpl.java:
@Service("lrInterfcae")
public class LoginRegistrationSerImpl implements LoginRegistrationService{
@Override
public void saveUser(RegistrationEntity reg) {
System.out.println("impl");
}
}
Register.xhtml:
<...
<h:commandButton value="REGISTER" id="register" action="#{register.registerUser()}" />
...>
