角度 RouteReuseStrategy 滚动位置错误。

当我从另一个页面返回列表页面时，滚动条回到顶部

import {ActivatedRouteSnapshot, DetachedRouteHandle, RouteReuseStrategy} from '@angular/router';

export class SystemRouteReuseStrategy implements RouteReuseStrategy {

  handlers: {[key: string]: DetachedRouteHandle} = {};

  shouldDetach(route: ActivatedRouteSnapshot): boolean {
    if (route.data.reuse) {
      return true;
    }
    return false;
  }

  store(route: ActivatedRouteSnapshot, handle: DetachedRouteHandle): void {
    this.handlers[route.routeConfig.path] = handle;
  }

  shouldAttach(route: ActivatedRouteSnapshot): boolean {
    return !!route.routeConfig && !!this.handlers[route.routeConfig.path];
  }

  retrieve(route: ActivatedRouteSnapshot): DetachedRouteHandle {
    return this.handlers[route.routeConfig.path]; 
  }

  shouldReuseRoute(future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean {
    return future.routeConfig === curr.routeConfig;
  }

}

这个超级DAO:

public class CrudDAO{

}

这个孩子班:

@Repository
public class JnsTimeDao extends CrudDAO {

}

@Repository
public class BatchDAO extends CrudDAO {
}

这个超级服务类

@Transactional(readOnly = true)
public abstract class CrudService<D extends CrudDAO> {

    @Autowired
    protected D dao;
}

启动错误:

org.springframework.beans.factory.NoUniqueBeanDefinitionException:没有定义[com.gp.dao.CrudDAO]类型的限定bean:期望的单个匹配bean但找到2:batchDAO,jnsTimeDao
