java - @FutureOrPresent 验证器有时会被违反，即使给定日期存在

Question

问题是当我尝试使用 post man 请求添加新记录时，有时会 因违反预期行为而违反一个或多个 Bean 验证约束@PresentOrFuture：这一定不会发生，因为给定日期总是new Date()

请求正文

{
    "objective": "test",
    "title": "test"
}

回复

{
    "path": "creation_date",
    "message": "creation date must be future or present.",
    "value": "2021-03-26T11:06:32.708Z[UTC]"
}
