关于注解问题

package com.imooc.sm.dao;

import com.imooc.sm.entity.Department;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository("departmentDao")
public interface DepartmentDao {
   void insert(Department department);
   void delete(Integer id);
   void update(Department department);
   Department selectById(Integer id);
   List<Department> selectAll();
}

package com.imooc.sm.service.Impl;

import com.imooc.sm.dao.DepartmentDao;
import com.imooc.sm.entity.Department;
import com.imooc.sm.service.DepartmentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;
@Service("departmentService")
public class DepartmentServiceImpl implements DepartmentService {

   /*@Autowired是按类型匹配，如果有多个DepartmentDao类的对象就会报错，
   可以配合@Qualifier("departmentDao")使用，  指定对象名，与@Resource效果一样，
   也可以直接使用@Resource*/
   @Qualifier("departmentDao")
   private DepartmentDao departmentDao;

   public void add(Department department) {
       departmentDao.insert(department);
   }

   public void remove(Integer id) {
       departmentDao.delete(id);
   }

   public void edit(Department department) {
       departmentDao.update(department);
   }

   public Department get(Integer id) {
       return departmentDao.selectById(id);
   }

   public List<Department> getAll() {
       return departmentDao.selectAll();
   }
}
这两个注解可以这样子用吗？
