Spring mvc 将Anotion添加到java类时出错

该行有多个标记
-无法将存储库解析为类型
-注释类型的属性值未定义

尝试将

@Repository（“loginDAO”）

添加到

loginDAOImpl.java

时出错。我不使用maven

@存储库（“loginDAO”） 公共类LoginDAOImpl实现LoginDAO{

 @Resource(name="sessionFactory")
 protected SessionFactory sessionFactory;

 public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
 }

 protected Session getSession(){
        return sessionFactory.openSession();
 }
public boolean checkLogin(String userName, String userPassword) {
    System.out.println("In Check login");
    Session session = sessionFactory.openSession();
    boolean userFound = false;
    //Query using Hibernate Query Language
    String SQL_QUERY =" from Users as o where o.userName=? and o.userPassword=?";
    Query query = session.createQuery(SQL_QUERY);
    query.setParameter(0,userName);
    query.setParameter(1,userPassword);
    List list = query.list();

    if ((list != null) && (list.size() > 0)) {
        userFound= true;
    }

    session.close();
    return userFound;
}

请同时添加相关代码。类路径中有哪些依赖项？
