org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'orderServiceimpl' defined in file [C:\study\core\out\production\classes\hello\core\Order\OrderServiceimpl.class]: Unsatisfied dependency expressed through constructor parameter 1: No qualifying bean of type 'hello.core.discount.DiscountPolicy' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Qualifier("mainDiscountPolicy")}

라고 뜨고 at hello.core.autowired.AllBeanTest.findAllBean(AllBeanTest.java:21)

여기가 문제라고 하는데 어떻게 해결할 수 있을까요...

ApplicationContext ac = new AnnotationConfigApplicationContext(AutoAppConfig.class, DiscountService.class);

위 코드입니다.
