使用Spring 3 +，Hibernate 4，Junit 4.8我得到以下无法自动装载字段 msg

DomainAwareBase是一个包含注释的抽象类

@TransactionConfiguration(defaultRollback=false)
@Transactional
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
    "classpath:test-springContext.xml"

UserDAOHibernateTest用于测试 UserDAOHibernate 实现

@Transactional
@Repository
public class UserDAOHibernate extends GenericDAOHibernate<User,Long > implements UserDAO { 
    @Transactional(readOnly = true)
    @Override
    public List<User> findAll() {

域类用户

    public User() {
    }

    public User(Long id) {
        this.id = id;

    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(columnDefinition = "int(10)", name = "AppUserId", nullable = false)
    private Long id;
    getters/setters and other fields not shown

当我注释掉 tx：annotationdriven 时，代码工作正常，否则我得到了BeanCreationError。我究竟做错了什么。非常感谢。

修改 GenericDAOHibernate 

public abstract class GenericDAOHibernate<T,ID extends Serializable> implements GenericDAO<T, ID>{   
    private Class<T> persistentClass;
    private Session session;

    @Autowired
    private SessionFactory sessionFactory;

    @Autowired
    public GenericDAOHibernate() {// need to know what is the class of the entity to persist find by reflection        
        this.persistentClass= (Class<T>)( (ParameterizedType) getClass().getGenericSuperclass() ).getActualTypeArguments()[0];                
    }
it has get/set session methods

答案 0 :(得分：0)

如果我们继续提议改变这个

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

这将无效，因为getClass()返回CGLIB正在创建的Proxy类。到

public GenericDAOHibernate() {
    this.persistentClass = getDaoClass();           
}

其中getDaoClass()将在子类中实现，例如

public Class<User> /* Class<T> in the parent class */ getDaoClass() {
    return User.class;
}

如果有效，我会添加其余的解释。
