JPA 属性转换器

Question

我尝试使用 JPA 转换器不成功。

转换器的类被实例化是因为 spring @Componente 注释，正如我在启动日志中看到的那样。

该项目不会抛出任何异常，只是不要执行转换器的覆盖方法。什么都没发生

你能帮帮我吗？

这是我的转换器

@Component
@Converter
public class ZonedTimestampConverter implements AttributeConverter<Date, Date>  {

    @Autowired
    private SessionData sessionData;

    public ZonedTimestampConverter() {
        System.out.println("++++++++++++++++  ZonedTimestampConverter !!!!!!  ++++++++++++");
    }

    @Override
    public Date convertToDatabaseColumn(Date attribute) {
        System.out.println("++++++++++++++++ NEED TO SET TIMEZONE HERE !!!!!!  ++++++++++++");
        return attribute;
    }

    @Override
    public Date convertToEntityAttribute(Date dbData) {
        System.out.println("++++++++++++++++ NEED TO SET TIMEZONE HERE !!!!!!  ++++++++++++");
        return dbData;
    }

}

这是我实体的属性：

@Column(name = "DATE_TIME", nullable = false, columnDefinition= "TIMESTAMP WITH TIME ZONE")
@Temporal(TemporalType.TIMESTAMP)
@JsonFormat(shape=JsonFormat.Shape.STRING, pattern="yyyy-MM-dd'T'HH:mm:ssZ")
@Convert(converter = ZonedTimestampConverter.class)
private Date dateTime;

这些是我的依赖项：

Answer 1

尝试添加泛型类型：

@Converter 
public class ZonedTimestampConverter implements AttributeConverter<Date, Date> {
    ....
}
