【问题描述】：
我对 Hibernate Validator 4.3.1 有疑问。
问题是，验证器正在验证字段为空且没有 @NotEmpty 注释。
当人的 web 表单被提交并且地址、电话、传真和网页未设置时，将引发验证错误。我认为这是错误的，因为没有 @NotEmpty 注释。我想跳过没有 @NotEmpty 注释的字段。
谁能解释问题出在哪里？谢谢。

@Override

return "Country [id=" + id + ", countryName=" + countryName + "]";
}
}
编辑 - 问题已解决。
问题出在"^" 表达式中。我必须改用"[^|]"。

澄清你的答案。您实际上在字段上有约束注释。没有任何注释就不会发生验证，但在您的情况下，您还使用了 @Pattern 注释，该注释对空字符串失败。
