javax.servlet.ServletException：HV000030：找不到类型的验证器：java.util.Date [重复]

Posted 2023-02-19

【中文标题】javax.servlet.ServletException：HV000030：找不到类型的验证器：java.util.Date [重复]

【英文标题】：javax.servlet.ServletException: HV000030: No validator could be found for type: java.util.Date [duplicate]

【问题描述】：

当我使用 JSF 2.1 并使用 JBoss 服务器提交表单时，出现标题异常。

我正在尝试使用和学习休眠注释。

我的实体 bean 是这样的：

@NotEmpty
@Temporal(TemporalType.DATE)
private Date date;

我收到此错误页面：

JBWEB000071: root cause

有人知道为什么吗？

谢谢，

【参考方案1】：

即使我不明白@NotEmpty 和@NotBlank 之间的相似之处，这篇文章也适合我：

Error with validator (No validator could be found for type: java.util.Date.)

问候，

编辑：

即使我在javax.servlet.ServletException: HV000030: No validator could be found for type: java.lang.Integer 收到重复问题的评论，我只想明确指出，这不仅发生在 Integers 上，而且还发生在 Dates 上，也许因为我们不知道还有多少其他类型。

我同意在使用注释之前尝试理解注释的说法，但我也说我们没有足够的文档。
