问题描述
当我根据 XSD 验证 XML 时出现此错误.模式和实例都是有效的，我可以在 XML 解析器中验证它们，但在 Java 中出现此错误:
I am getting this error when I am validating XML against my XSD. Both schema and instance are valid and I am able to validate them in XML parsers but I am getting this error in Java:

I tried so many variations of schema location and xmlns but I am getting that error no matter what I tried.
推荐答案
XSD 的目标命名空间是 https://www.company.com/mine.
The target namespace of your XSD is https://www.company.com/mine.
您将此作为 XML 根元素 (fieldsMapper) 的默认命名空间.
You have this as the default namespace of the root element (fieldsMapper) of your XML.
到目前为止一切顺利.
但是您的 schemaLocation 使用了不同的命名空间 URI:
But your schemaLocation uses a different namespace URI:
xsi:schemaLocation="https://www.company.com/mine/fieldsMapper fieldsMapper.xsd"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
改成
xsi:schemaLocation="https://www.company.com/mine fieldsMapper.xsd"
你的问题就会得到解决.
and your problem will be solved.
