javax.persistence中的时态类型（必须指定时态类型）

我有这个运行时异常问题（在关系数据库和Java容器中使用基于对象的关系持久性解决方案）

但是，看在上帝的份上，类型已经是java.util.Date

@Temporal(TemporalType.TIMESTAMP)
    @Column(name = "SUBMISSION_TIME")
    public Date getSubmissionTime() {
        return this.submissionTime;
    }

这里是完整的堆栈跟踪

Exception Description: The attribute [submissionTime] from the entity class [class com.tdk.domain.Service] does not specify a temporal type. A temporal type must be specified for persistent fields or properties of type java.util.Date and java.util.Calendar.

@Chris comment是对的（是否拾取列批注和时态批注？将日志设置为“最精细”或“全部”，并检查EclipseLink在其部署阶段拾取的内容。如果在字段和属性上有批注，则只拾取一组批注。此外，还应检查您的类版本是否与运行时拾取的版本相同-不会这不是第一次多个版本的类引起奇怪的运行时问题了）

这是一个什么“编译”问题
