从数据库加载joda LocalTime

Question

我正在使用Joda Time和Jadira用户类型库来保存我的数据库中的Joda LocalTime。

这是我的实体

@Entity
public class Airport implements Serializable {

    private static final long serialVersionUID = 6382228467347085567L;

    public String getNameIATA() {
        return nameIATA;
    }

    public void setNameIATA(String nameIATA) {
        this.nameIATA = nameIATA;
    }

    public int getSsliaLevel() {
        return ssliaLevel;
    }

    public void setSsliaLevel(int ssliaLevel) {
        this.ssliaLevel = ssliaLevel;
    }

    public String getLatitude() {
        return latitude;
    }

    public void setLatitude(String latitude) {
        this.latitude = latitude;
    }

    public String getLongitude() {
        return longitude;
    }

    public void setLongitude(String longitude) {
        this.longitude = longitude;
    }

    public int getAltitude() {
        return altitude;
    }

    public void setAltitude(int altitude) {
        this.altitude = altitude;
    }

    public String getComments() {
        return comments;
    }

    public void setComments(String comments) {
        this.comments = comments;
    }

    public AirportCategoryE getCategory() {
        return category;
    }

    public void setCategory(AirportCategoryE category) {
        this.category = category;
    }

    public Minutes getTaxiTime() {
        return taxiTime;
    }

    public void setTaxiTime(Minutes taxiTime) {
        this.taxiTime = taxiTime;
    }

    public Minutes getDepTimeOffset() {
        return depTimeOffset;
    }

    public void setDepTimeOffset(Minutes depTimeOffset) {
        this.depTimeOffset = depTimeOffset;
    }

    public Minutes getArrTimeOffset() {
        return arrTimeOffset;
    }

    public void setArrTimeOffset(Minutes arrTimeOffset) {
        this.arrTimeOffset = arrTimeOffset;
    }

    public List<Runway> getRunways() {
        return runways;
    }

    public void setRunways(List<Runway> runways) {
        this.runways = runways;
    }

    public List<Fueler> getFuelers() {
        return fuelers;

    public void setFuelers(List<Fueler> fuelers) {

    }

    public List<Handling> getHandlings() {

    public LocalTime getOpeningTime() {
        return openingTime;
    }

    public void setOpeningTime(LocalTime openingTime) {
        this.openingTime = openingTime;
    }

    public LocalTime getClosingTime() {
        return closingTime;
    }

    public void setClosingTime(LocalTime closingTime) {
        this.closingTime = closingTime;
    }

}

这是我的道歉

@Singleton
@Startup
@LocalBean
public class AirportDaoImpl implements AirportDao {

    @PersistenceContext(unitName = "flightfaq")
    protected EntityManager em;

    /** JPQL query to find a {@link Airport} given its OACI name */
    private static final String JPQL_FIND_BY_NAME = "SELECT a FROM Airport a WHERE a.nameOACI=:nameOACI";

    @Override
    public Airport find(String nameOACI) throws DAOException {
        Airport airport = null;
        try {
            TypedQuery<Airport> findQuery = em.createQuery(JPQL_FIND_BY_NAME,
                    Airport.class).setParameter("nameOACI", nameOACI);
            airport = findQuery.getSingleResult();
        } catch (NoResultException e) {
            airport = null;
        } catch (Exception e) {
            throw new DAOException(e);
        }
        return airport;
    }

}

问题在于，当我用有效名称调用DAO时，我得到了

正如您在堆栈末尾看到的那样，有

Caused by: org.hibernate.PropertyAccessException: could not set a field value by reflection setter of com.flightfaq.beans.business.Airport.closingTime

但也

Can not set org.joda.time.LocalTime field com.flightfaq.beans.business.Airport.closingTime to org.joda.time.LocalTime

这是我用来输入数据库中有问题的机场的SQL命令

INSERT INTO `Airport` (`id`, `altitude`, `arrTimeOffset`, `category`, `closingTime`, `comments`, `depTimeOffset`, `latitude`, `longitude`, `nameIATA`, `nameOACI`, `openingTime`, `ssliaLevel`, `taxiTime`) VALUES
(1, 499, '0', 'A', '00:00:00', 'se garer au parking R12', '15', '433806N', '0012204E', 'TLS', 'LFBO', '00:00:00', 4, '0');

我在关闭时间进入'00：00：00'。

Answer 1

您closingTime的数据库中应该有time类型 如果您想在数据库中使用varchar[]类型，那么您应该使用自己的usertype

应该看起来像

public class LocalTimeType implements UserType {
    public int[] sqlTypes() {
        return new int[] {
                Types.VARCHAR,
        };
    }

    public Class getReturnedClass() {
        return LocalTime.class;
    }

    public Object nullSafeGet(ResultSet rs, String[] names, Object owner) throws SQLException {
       ...
    }

    public void nullSafeSet(PreparedStatement st, Object value, int index) throws SQLException {
      ...
    }

    ...
}
