javax.servlet.ServletException：HV000030：找不到可用於類型爲java.util.Date的驗證程序

當我使用JSF 2.1提交表單並使用JBoss服務器時，出現標題異常。javax.servlet.ServletException：HV000030：找不到可用於類型爲java.util.Date的驗證程序

我想使用和學習hibernate註釋。

我的實體Bean是這樣的：

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

我得到這個錯誤頁面：

JBWEB000071: root cause

是否有人知道這是爲什麼？

謝謝

即使我不明白@NotEmpty和@NotBlank之間的相似性，這個帖子對我的作品：

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

問候，

編輯：

即使我g在javax.servlet.ServletException: HV000030: No validator could be found for type: java.lang.Integer的重複問題的註釋我只是想明確說明，這不僅發生在整數，而且還與日期，也許我們不知道有多少其他類型。

我同意在使用它們之前試圖理解註釋的說法，但我也說我們沒有足夠的文檔來解決這個問題。
