Hibernate-java8似乎不适用于从MSSQL smalldatetime到java.time.Instant的转换

我在Gradle、Spring4和Hibernate的一个项目中工作

我想从MicrosoftSQLServerExpress（64位）11.0.3156.0版获取一个类型为smalldatetime的日期列

这是一个非常简单的类

   @Entity
    public class TimeSlot {
      @Id
      private int dayOfWeek;
      protected Instant start;
      protected Instant end;

      public TimeSlot(){
      }
      ... getters and setters ...
    }

当我运行这个时，我得到了一个例外：

正如我在中看到的，只需添加org.hibernate:hibernate-java8:5.0.4.Final就不需要javax.persistence.Converter，只需将您的实体映射为java.time.Instant或java.time中的其他内容，就可以了

但不是我的情况，我仍然得到“org.hibernate.type.SerializationException:无法反序列化”

请问，有人能帮我吗？有一些配置错误吗

提前感谢。

您还记得是否找到了解决此问题的方法吗？不幸的是，没有

compile('org.springframework.data:spring-data-jpa:1.9.1.RELEASE')
compile('org.hibernate:hibernate-entitymanager:5.0.5.Final')
compile('org.hibernate:hibernate-java8:5.0.4.Final')
compile('org.hibernate:hibernate-core:5.0.5.Final')
