錯誤：無法找到類型爲驗證程序：java.lang.Integer？

Question

我正在與Spring一起開發一個項目，爲什麼我一直在收到以下錯誤？

javax.validation.UnexpectedTypeException：沒有驗證可以找到類型：java.lang.Integer中

看起來這是類似於我在前面面對，this post幫助了我。

Answer 2

根據javadoc of NotEmpty，Integer不是它要檢查的有效類型。它適用於字符串和集合。如果你只是想確保一個整數有一定的價值，javax.validation.constraints.NotNull是你所需要的。

public @interface NotEmpty

Asserts that the annotated string, collection, map or array is not null or empty.
