我正在尝试实施factory设计模式。
我创建了一个interface IAuthenticationHandler
public interface IAuthenticationHandler {
public boolean validate(User user);
}
并在AuthenticationHandler
中实现public class AuthenticationHandler extends IAuthenticationHandler{
private UserDao userDao;
@Override
public boolean validate(User user){
// validate logic
}
}
我使用Spring创建AuthenticationHandler的bean
authenticationHandler = (AuthenticationHandler) StaticContextHolder
.getBean("authenticationHandler");
但是我得到了BeanCreationException。我添加了stacktrace。
