java - TimestampType 设置覆盖错误

Question

我正在尝试创建自己的 Hibernate 映射以使用 Hibernate 将 UTC 时间戳读写到 DB，因此我正在扩展 Hibernate TimestampType 类，如下所示，但我总是收到以下错误。那么有人可以告诉我我在这里做错了什么吗？感谢您的宝贵时间。

Multiple markers at this line - The method set(PreparedStatement, Object, int) of type UTCTimestampType must override or implement a supertype method - Name clash: The method set(PreparedStatement, Object, int) of type UTCTimestampType has the same erasure as set(PreparedStatement, T, int) of type AbstractSingleColumnStandardBasicType but does not override it

public class UTCTimestampType extends org.hibernate.type.TimestampType{

        @Override
        public Object get(ResultSet rs, String name) throws SQLException {
            return rs.getTimestamp(name, createUTCCalendar());
        }

        private static Calendar createUTCCalendar() {
            final Calendar c = Calendar.getInstance();
            c.setTimeZone(new SimpleTimeZone(0, "UTC"));
            return c;
        }

        @Override
        public void set(PreparedStatement st, Object value, int index)
                    throws SQLException{
            Timestamp ts;
            if (value instanceof Timestamp) {
                ts = (Timestamp) value;
            } else {
                ts = new Timestamp(((java.util.Date)value).getTime());
            }
            st.setTimestamp(index, ts, createUTCCalendar());
        }   
}

查看 TimestampType 的 Java 文档:

TimestampType它延伸

AbstractSingleColumnStandardBasicType<Date>

方法签名是 set(PreparedStatement st, T value, int index) 而不是 Object

尝试:

@Override
        public void set(PreparedStatement st, Date value, int index)
                    throws SQLException{...
