在 wildfly 19 中，为什么我收到 javax.faces.FacesException: javax.servlet.jsp.JspException: a minimum and/or a maximum have to be specified？

Question

我正在将一个非常旧的应用程序从 jboss 6 迁移到 wildfly 19。它基于 EJB2 和 JSF1.2 - MyFaces。应用程序已部署，但是当我尝试访问其中一个 JSP 页面（用 JSF 包装）时，我收到一个错误，它什么也没告诉我。有没有人可以知道这是什么意思？提前感谢您的帮助。

获取堆栈跟踪时，请始终查看最底层的根本原因。答案通常就在那里。

从下到上仔细读出类/方法名称，直到某些部分变得有意义：

• BiorderFilter.jsp 文件正在服务中
• <f:view>标签
• <t:html>标签
• <t:documentBody>标签
• <h:form>标签
• <h:panelGrid>标签
• <h:inputText>标签
• <f:validateLongRange>标签
• 标签开始
• 创建ValidateLongRangeTag 类型的验证器
• 创建GenericMinMaxValidatorTag 类型的验证器
• 问题：“必须指定最小值和/或最大值”

所以很可能您有一个带有<f:validateLongRange> 标记的BiorderFilter.jsp 文件，而该文件没有指定minimum 和/或maximum 属性。

<h:inputText ...>
   <f:validateLongRange />
</h:inputText>

只需指定至少一个具有非null 值的属性，这个问题就会消失。例如：

<h:inputText ...>
   <f:validateLongRange minimum="0" />
</h:inputText>

或者可能整个验证器对于特定输入是不必要的，您最好将其删除。众所周知，一些开发人员使用这种方式来确保输入的值是Long，而不是例如。 Double。但是为此应该使用Converter 而不是Validator，或者只是一个严格类型的<h:inputText value="#{bean.value}">，其中value 是Long 类型，以便JSF 自己进行自动转换。
