java - SSH整合時 getHibernateTemplate()為空

Question

@Repository
public class AuthorAdminDaoImpl implements IAuthorAdminDao {
    @Resource
    private BaseDAO basedao;
public boolean loginAuthorAdmin(AuthorAdmin aa) {
        try {
            String queryString = " from AuthorAdmin  a where a.authorName= ? and a.authorPwd= ? ";
            basedao=new BaseDAO();
            if (basedao.getTemplate() == null) {
                System.out.println("没有获得HibernateTemplate?");
            }
            List<AuthorAdmin> find = (List<AuthorAdmin>) basedao.getTemplate().find(
                    queryString, aa.getAuthorUsername(), aa.getAuthorPwd());
            if (find != null && find.size() > 0) {
                return true;
            } else {
                return false;
            }
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException();
        }


}
    }

public class BaseDAO extends HibernateDaoSupport{

    public HibernateTemplate getTemplate(){
        return getHibernateTemplate();
    }

}

HibernateTemplate為空不知道為什麼？用的是Spring注入

本來 Spring 已經幫你把 basedao 注入了你XML裡配置好的物件, 你後面又用

basedao = new BaseDAO();

創建了個新物件, 把那個 Spring 給注入的 bean 替換掉了...
