LocalDateTime，ZonedDateTime和时间戳

我有一个SpringBoot应用程序.使用Spring Initializer，嵌入式Tomcat，Thymeleaf模板引擎以及作为可执行JAR文件的软件包.

I have a SpringBoot app. using Spring Initializer, embedded Tomcat, Thymeleaf template engine, and package as an executable JAR file.

我有一个具有2个属性(initDate，endDate)的域对象.我想创建2个转换器来处理mySQL DB

I have a domain object with 2 properties (initDate, endDate). I want to create 2 converters to deal with mySQL DB

@Convert(converter = LocalDateTimeAttributeConverter.class) 
private LocalDateTime initDate;

@Convert(converter = ZonedDateTimeAttributeConverter.class) 
private ZonedDateTime endDate;

转换器1(可以)

@Converter
public class LocalDateTimeAttributeConverter implements AttributeConverter<LocalDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime localDateTime) {
        return (localDateTime == null ? null : Timestamp.valueOf(localDateTime));
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp sqlTimestamp) {
        return (sqlTimestamp == null ? null : sqlTimestamp.toLocalDateTime());
    }
}

这是我要创建的那个

@Converter
public class ZonedDateTimeAttributeConverter implements AttributeConverter<ZonedDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(ZonedDateTime zoneDateTime) {
        return (zoneDateTime == null ? null : Timestamp.valueOf(zoneDateTime));
    }


    @Override
    public ZonedDateTime convertToEntityAttribute(Timestamp sqlTimestamp) {
        return (sqlTimestamp == null ? null : sqlTimestamp.toZonedDateTime());
    }
}

但是我不能，因为我有两个错误:

But I can't because I have 2 errors:

The method valueOf(String) in the type Timestamp is not applicable for the arguments (ZonedDateTime)

，并且时间戳记没有方法toZonedDateTime()

and the TimeStamp does not have the method toZonedDateTime()

如果我不为ZonedDate添加任何转换器，JPA将创建一个类型为varbinary(255)

and if I don't add any converter for the ZonedDate, JPA creates a table with the type varbinary(255)
