Hibernateは更新用のSQLコードを生成しません

Question

私はHibernateでSpring MVCアプリケーションを持っています。以前は、各エンティティのセッション（データベース）で動作するクラスがあり、すべてがうまくいきました。さて、私は抽象的なDaoクラスを持っています。これは各エンティティのために1つのクラスによって継承されています。私はデータベースに新しいデータを挿入する場合、すべてがうまくいきます。しかし、私はデータを更新したいとき、コントローラに到達します（私はコンソールでそれらを印刷することができます）が、Hibernateは更新用のSQLコードを生成しません。私はSQLを表示するためにHibernateのプロパティをオンにし、UPDATEを除くすべてのSQLクエリをハイバーネーションが生成したことがわかりました。抽象クラスのすべてのメソッドは、更新メソッドを除いて動作します。

そして興味深いのは、は、がコンソールにerorを取得しないということです。

この交差点クラスです

@Entity 
@Table(name = "intersections") 
public class Intersection implements Serializable { 
    private static final long serialVersionUID = 1L; 
    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Basic(optional = false) 
    @Column(name = "id") 
    private Integer id; 
    @Column(name = "symbol") 
    private Integer symbol; 
    @Size(max = 256) 
    @Column(name = "title") 
    private String title; 

    @OneToMany(mappedBy = "intersection",cascade = CascadeType.ALL) 
    private List<Access> accessList; 

アクセスクラス

@Entity 
@Table(name = "accesses") 
public class Access implements Serializable { 
    private static final long serialVersionUID = 1L; 
    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Basic(optional = false) 
    @Column(name = "id") 
    private Integer id; 
    @Column(name = "symbol") 
    private Integer symbol; 
    @Size(max = 50) 
    @Column(name = "title") 
    private String title; 

    @JoinColumn(name = "intersection", referencedColumnName = "id") 
    @ManyToOne(cascade = CascadeType.ALL) 
    private Intersection intersection; 

抽象クラス

public abstract class AbstractDao<T, I, A, P, ID extends Serializable> implements DaoInterface<T, I, A, P, ID>{ 

    @Autowired 
    private SessionFactory sessionFactory; 
    private Class<T> classType; 

    public AbstractDao(){ 
     ParameterizedType type = (ParameterizedType) getClass().getGenericSuperclass(); 
     this.classType = (Class<T>)type.getActualTypeArguments()[0]; 
    } 

    @Override 
    public void insert(T t) { 
     Session session = sessionFactory.getCurrentSession(); 
     session.save(t); 
    } 

    @Override 
    public void update(T t) { 
     Session session = sessionFactory.getCurrentSession(); 
     session.update(t); 
    } 

    @Override 
    public List<T> getAll() { 
     Session session = sessionFactory.getCurrentSession(); 
     Criteria c = session.createCriteria(classType); 
     c.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY); 
     c.addOrder(Order.asc("symbol")); 
     List<T> list = c.list(); 
     return list; 
    } 

    @Override 
    public T getById(ID id) { 
     Session session = sessionFactory.getCurrentSession(); 
     T a = (T)session.get(classType, id); 
     return a; 
    } 

    @Override 
    public List<T> getByIntersection(I i) { 
     Session session = sessionFactory.getCurrentSession(); 
     Criteria c = session.createCriteria(classType); 
     c.add(Restrictions.eq("intersection", i)); 
     c.addOrder(Order.asc("symbol")); 
     List<T> list = c.list(); 
     return list; 
    } 

    @Override 
    public List<T> getByAccess(A a) { 
     Session session = sessionFactory.getCurrentSession(); 
     Criteria c = session.createCriteria(classType); 
     c.add(Restrictions.eq("access", a)); 
     c.addOrder(Order.asc("symbol")); 
     List<T> list = c.list(); 
     return list; 
    } 

    @Override 
    public List<T> getByPole(P p) { 
     Session session = sessionFactory.getCurrentSession(); 
     Criteria c = session.createCriteria(classType); 
     c.add(Restrictions.eq("pole", p)); 
     c.addOrder(Order.asc("symbol")); 
     List<T> list = c.list(); 
     return list; 
    } 

AccessDao

public class AccessDao extends AbstractDao<Access, Intersection, Access, Pole, Integer>{ 

}

@RequestMapping(value = "/access", method = RequestMethod.POST) 
    public String accessUpdate(
      @RequestParam Integer idInt, 
      @RequestParam Integer idAccess,
