问题报错信息：
org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.kemile.discount.service.DiscountDetailsService com.kemile.discount.controller.DiscountDetailsController.discountDetailsService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.kemile.discount.service.DiscountDetailsService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:561)

代码如下：
控制层：
@Controller
@RequestMapping("/DiscountDetails")
public class DiscountDetailsController {

@Autowired
private DiscountDetailsService discountDetailsService;

实现层：
public class DiscountDetailsServiceImpl extends AbstractPageService<IBaseDAO<DiscountDetails>, DiscountDetails> implements DiscountDetailsService<IBaseDAO<DiscountDetails>, DiscountDetails> {

@Autowired
private DiscountDetailsDAO discountDetailsDAO;

public IBaseDAO<DiscountDetails> getDao() { return discountDetailsDAO; }

public DiscountDetailsDAO getDiscountDetailsDAO() {
return discountDetailsDAO;
}

public BizData4Page checkDiscountDetails(@PathVariable int page, @RequestParam Map<String, Object> conditions){
return discountDetailsDAO.checkDiscountDetails(page,conditions);
}

接口层：

public interface DiscountDetailsService <D extends IBaseDAO<T>, T extends BaseDomain> extends IPageService<D, T>, IBaseService<D, T> {

BizData4Page checkDiscountDetails(@PathVariable int page, @RequestParam Map<String, Object> conditions);
}

实体层：
public class DiscountDetails extends BaseDomain {
private long phone;
private int count;

public int getCount() {
return count;
}

public void setCount(int count) {
this.count = count;
}

public long getPhone() {
return phone;
}

public void setPhone(long phone) {
this.phone = phone;
}
}

DAO层：
public interface DiscountDetailsDAO extends IBaseDAO<DiscountDetails> {

BizData4Page checkDiscountDetails(@PathVariable int page, @RequestParam Map<String, Object> conditions);

}
