    @Autowired
    public void setServiceUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

道

@Repository
public class UserDaoImpl implements UserDao {

    private Session session;

    public UserDaoImpl(){
        this.session = Main.getSessionFactory().getCurrentSession();
        session.beginTransaction();
    }

我搜索了我的问题，但没有找到有用的东西。谢谢

Answer 1

你能验证 "project" 吗？里面<context:component-scan base-package="project" />确实是包名，其中 @Service小号，@Controller类是？

解决 ServiceUserDao 后可能会遇到的另一个问题是你得到UserDaoImpl无法 Autowiring 。这是因为您还没有启用对@Repository 的扫描。 .如果我没记错的话 <context:annotation-config/>不是在扫描 JPA 内容。

所以尝试添加:

<beans:beans  ...
    ...
    xsi:schemaLocation="....
    http://www.springframework.org/schema/data/jpa
    http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">

<!-- Scan @Repositories -->
<repositories base-package="xxx.repositories" />
