标签: spring google-app-engine spring-mvc jpa-2.0 dao

我正在尝试使用Google AppEngine构建一个完整的服务器。 我习惯用springframework + jpa创建一个但是当我在调试中午餐时我遇到了一些问题。 我以这种方式配置了我的项目:

像这样的域名

@Entity
public class User implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Key key;
.......

dao喜欢这个

    public interface UserDAO extends JpaDao<User> {

.....
像这样的

daoImpl

@Repository
@Transactional
public class WineDAOImpl extends AbstractJpaDao<Wine> implements WineDAO {


    @PersistenceContext(unitName = "transactions-optional")
    private EntityManager entityManager;

    private final static Set<Class<?>> dataTypes = new HashSet<Class<?>>(Arrays.asList(new Class<?>[] { Wine.class }));


    public EntityManager getEntityManager() {
        return entityManager;
    }

.....

服务

 public interface UserService {
.....

服务Impl

@Service("UserService")
@Transactional
public class UserServiceImpl implements UserService {

    @Autowired
    protected UserDAO userDAO;
.....

这是我的mvc-dispatcher-servlet

    </bean>

        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

</beans>

最后我的percistence.xml

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
    version="1.0">

    <persistence-unit name="transactions-optional">
        <provider>org.datanucleus.api.jpa.PersistenceProviderImpl</provider>
        <class>xx.xxxxx.xxxxxx.domain.User</class>
        <properties>
            <property name="datanucleus.NontransactionalRead" value="true" />
            <property name="datanucleus.NontransactionalWrite" value="true" />
            <property name="datanucleus.ConnectionURL" value="appengine" />
            <property name="datanucleus.appengine.datastoreReadConsistency"
                value="EVENTUAL" />
            <property name="javax.persistence.query.timeout" value="5000" />
            <property name="datanucleus.datastoreWriteTimeout" value="10000" />
        </properties>
    </persistence-unit>

</persistence>

但是当我尝试调试我的代码时,我收到此错误
