找到解决方案.我需要在标记属性中明确声明类型，例如:

Solution found. I needed to explicitly declare the type on my tag attributes, like:

<%@ attribute name="currentPage" required="true" type="java.lang.Long" %>
<%@ attribute name="totalPages" required="true" type="java.lang.Long" %>

我怀疑没有声明的类型，两个属性都被解释为字符串，并且标签在数字的字符串值之间进行了字典比较.我认为文字值10是有效的，因为JSP解释器将其识别为适当的数字类型，然后自动将比较中的另一个参数转换为匹配.

I suspect that without the declared type both attributes were being interpreted as Strings, and the tag was doing a lexicographical comparison between the string values of the numbers. I assume a literal value of 10 worked because the JSP interpreter recognized it as a proper numerical type and then automatically converted the other argument in the comparison to match.

长话短说，请始终在标签属性上声明type.否则会发生令人困惑的事情.

So long story short, always declare a type on your tag attributes. Otherwise very confusing things can happen.
