1、接口注入问题：
@Controller
@Scope("prototype")
public class GenuineManagementAction extends BaseAction {
private static final long serialVersionUID = -3797612994929924322L;
@Resource
private GenuineManagementService genuineManagementService;
@Resource//这样写是有问题的，去掉即可正常
private GenuineManagement genuineManagement;
}
@Resource代表注入，只有接口才能注入，而GenuineManagement 是一个实体类，所以加上@Resource 会报如下错误：
Unable to instantiate Action, genuineManagementAction,
No matching bean of type [com.vrv.paw.domain.GenuineManagement] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
