Hibernate 从数据库加载joda LocalTime

我正在使用Joda Time和Jadira用户类型库在数据库中持久化我的Joda LocalTime

这是我的实体

@Entity

    }

}

而且

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

下面是我用来在数据库中输入问题机场的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');

我输入了“00:00:00”作为关闭时间。

您的

closingTime

应该在数据库中输入

time

。
如果您想在数据库中使用

varchar[]

类型，那么您应该使用自己的用户类型

应该是这样的

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 {
      ...
    }

    ...
}

我正在考虑实现我自己的UserType，将Joda'LocalTime'转换为字符串。（例如LocalTime:08h23m=>String“0823”）您所说的是，如果我手动将LocalTime转换为varchar数据库对象。这可能就是我要做的。但是使用jadira，数据库中的类型被正确设置为TIME。我不明白这个例外

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

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');

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 {
      ...
    }

    ...
}
