我正在使用 spring 3.1 和 hibernate 3.6 制作分类广告网站。我有四个实体(User、UserRole、Advertisement 和 Category)。我为每个类(class)使用一个单独的 dao。 User 和 UserRoles 在 Daos 中的所有操作都可以正常工作。但是在 Advertisement 和 Category 的 daos 中，保存/更新会抛出一个 SQLGrammarException。

广告类

    @Entity
    @Table(name="ads")
    public class Advertisement implements Serializable {

        private static final long serialVersionUID = 1L;

        @Id
        @GeneratedValue
        @Column(name = "AD_ID")
        private String adId;

        @ManyToOne(cascade = CascadeType.ALL)
        @JoinColumn(name="CAT_ID" )
        private Category category;

        @ManyToOne(cascade = CascadeType.ALL)
        @JoinColumn(name="USER_ID" )
        private User user;


        @Column(name = "TITLE")
        private String title;

        @Column(name = "DESC", nullable = true)
        private String desc;

        @Column(name = "PRICE")
        private double price;

        @Column(name ="IMG1" , nullable = true)
        private String imageOne;

        @Column(name ="IMG2" , nullable = true)
        private String imageTwo;

        @Column(name ="IMG3" , nullable = true)
        private String imageThree;

        @Temporal(TemporalType.TIMESTAMP)
        @Column(name ="CREATED")
        private Date createdOn;

        //Getters and setters
    }

类别类

    @Entity
    @Table(name="cats")
    public class Category implements Serializable {

        private static final long serialVersionUID = 1L;

        @Id
        @GeneratedValue
        @Column(name = "CAT_ID")
        private String catId;

        @Column(name = "CAT_NAME", unique=true)
        private String catName;

        @Column(name ="DESC" , nullable = true)
        private String desc;

        @OneToMany(mappedBy="category", fetch=FetchType.LAZY)
        private List<Advertisement> allAds;

        //getters and setters
    }

广告道

    @Repository
    @Transactional
    public class AdvertisementDaoImpl implements AdvertisementDao {

        private HibernateTemplate hibernateTemplate;

        @Autowired
        public void setSessionFactory(SessionFactory sessionFactory) 
        {
            this.hibernateTemplate = new HibernateTemplate(sessionFactory);
        }

        @Override
        public void save(Advertisement ad) 
        {       
            hibernateTemplate.save(ad);

        }

        @Override
        public void update(Advertisement ad) {
            hibernateTemplate.update(ad);

        }

        @Override
        public void delete(Advertisement ad) {
          hibernateTemplate.delete(ad);

        }

        @Override
        public Advertisement getAdById(String adId) {

            Advertisement ad = (Advertisement) hibernateTemplate.get(Advertisement.class, adId);

            return ad;
        }

        @SuppressWarnings("unchecked")
        @Override
        public List<Advertisement> getAdsByUserId(String userId) {

            String sql = "SELECT * FROM ads USER_ID = :uID";

            List <Advertisement> adList= new ArrayList<Advertisement>();

            Query qry = hibernateTemplate.getSessionFactory().getCurrentSession().
                        createSQLQuery(sql)
                        .addEntity(Advertisement.class)
                        .setParameter("uID", userId);

            adList = ( List <Advertisement> ) qry.list();

            return adList;
        }

    }

表格

        CREATE TABLE IF NOT EXISTS `ads` (
          `AD_ID` int(10) unsigned NOT NULL AUTO_INCREMENT,
          `CAT_ID` int(10) unsigned NOT NULL,
          `USER_ID` int(10) unsigned NOT NULL,
          `TITLE` varchar(200) NOT NULL,
          `PRICE` double unsigned NOT NULL,
          `DESC` varchar(2000) DEFAULT NULL,
          `IMG1` varchar(400) DEFAULT NULL,
          `IMG2` varchar(400) DEFAULT NULL,
          `IMG3` varchar(400) DEFAULT NULL,
          `CREATED` timestamp NOT NULL,
          PRIMARY KEY (`AD_ID`),
          KEY `CAT_ID` (`CAT_ID`),
          KEY `USER_ID` (`USER_ID`)
        ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
        ALTER TABLE `ads`
          ADD CONSTRAINT `ads_ibfk_2` FOREIGN KEY (`USER_ID`) REFERENCES `users` (`USER_ID`) ON DELETE CASCADE ON UPDATE CASCADE,
          ADD CONSTRAINT `ads_ibfk_1` FOREIGN KEY (`CAT_ID`) REFERENCES `categories` (`CAT_ID`) ON DELETE CASCADE ON UPDATE CASCADE;

调用保存方法

            Advertisement ad2= new Advertisement();

            ad2.setCategory(categoryDao.getAllCategories().get(2));

            ad2.setUser(UserService.getCurrentUser());
            ad2.setImageOne(null);
            ad2.setImageTwo(null);
            ad2.setImageThree(null);

            ad2.setCreatedOn(new Date());

            ad2.setPrice(102.0);

            ad2.setTitle("New ad");

            ad2.setDesc("descriptions");
            advertisementDao.save(ad2);

这是错误

我尝试删除 ManytoOne 关联(删除 USER_ID 和 CAT_ID FK)，但我无法保存到这两个表。但是我可以通过调用 advertisementDao.getAdById(id) 来获取 Advertisement 类的对象，它还会自动加载相关的 Category 对象和 User 对象。我还将所有四个类添加到 hibernate 配置文件中。

我看不出是什么导致了这个错误。最后，我尝试通过从 session 中获取查询对象以传统方式创建 SQL 插入查询。它也给出了同样的错误。请帮我。谢谢

最佳答案

DESC 是 MySQL 中的保留字，因此不能将其用作列名。您应该重命名您的列以使插入工作。
