EJB失去@MappedSuperclass属性

问题描述

我有WebService，它通过EJB获取日期，但结果是我缺少映射超类中的attibute

@Entity
@Table(name = "REASON",schema = "XXX")
@NamedQueries({
})
@requiredArgsConstructor
@Getter
@Setter
@EqualsAndHashCode(callSuper = true)
@ToString(callSuper = true)
public class Reason extends SSEntity implements Serializable {

    private static final long serialVersionUID = -7071943771305035766L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "REASON_ID")
    private Long reasonId;

    @NotNull
    @Column(name = "INTERNAL_ID")
    private Long internalId;   
 
}

映射的超类

@MappedSuperclass
@requiredArgsConstructor
@EqualsAndHashCode
@ToString
public abstract class SSEntity {

    @NotNull
    @Version
    @Column(name = "UPDATE_TIMESTAMP",nullable = false)
    @Setter
    @Getter(onMethod=@__({@XmlJavaTypeAdapter(XmlTimestampAdapter.class)}))
    private Timestamp updateTimestamp;

}

我有列出原因的Web服务方法，但是如果我使用EJB，则不会获得更新时间戳记属性

@WebService(name = "IIntegrationInboundRemoteWSSEI",targetNamespace = "http://XXX.WebServices")
public interface WebService {

    @WebMethod
    List<Reason> listReasonsAllEJB() throws Exception;

    @WebMethod
    List<Reason> listReasonsAll() throws Exception;    
}

网络服务实现

@Stateless
@WebService(
        serviceName = "RemoteWebService",targetNamespace = "http://XXX.WebServices",endpointInterface = "com.azs.ws.WebService",portName = "RemoteWebServicePort"
)
public class WebServiceImpl implements WebService {

    @EJB(beanName = "WsEJBImpl")
    private WsEJB bean;

    @Inject
    private EntityManager entityManager;

    @Override
    public List<Reason> listReasonsAllEJB() throws Exception {
        return bean.listRejectionReasonsAll();
    }

    @Override
    public List<Reason> listReasonsAll() throws Exception {
        return entityManager
                .createNamedQuery("listReasons",Reason.class)
                .setParameter("date",new Date())
                .getResultList();
    }

}

EJB如下

@Remote
public interface WsEJB {

    List<Reason> listReasonsAll() throws Exception;    

}

EJB实现

@Stateless
@Remote(WsEJB.class)
public class WsEJBImpl implements WsEJB {

    @Inject
    private EntityManager entityManager;

    @Override
    public List<Reason> listReasonsAll() throws Exception {
        return entityManager
                .createNamedQuery("listReasons",new Date())
                .getResultList();
    }

}

如您所见，方法 listReasonsAllEJB（）和 listReasonsAll（）都相同

当我用SoapUI测试这些方法时，我得到了

使用EJB时，我丢失了updateTimestamp属性，我丢失了什么？..

解决方法

我的abstarct实体类必须序列化

    @MappedSuperclass
    public abstract class SSEntity implements Serializable {

        private static final long serialVersionUID = -5741595897057015891L;
    
        @NotNull
        @Version
        @Column(name = "UPDATE_TIMESTAMP",nullable = false)
        @Setter
        @Getter(onMethod=@__({@XmlJavaTypeAdapter(XmlTimestampAdapter.class)}))
        private Timestamp updateTimestamp;
    
    }
