获取错误属性 xsi:noNamespaceschemaLocation 是不允许的

Question

我收到此错误：

错误:(7, 50) cvc-complex-type.3.2.2: 属性“xsi:noNamespaceschemaLocation”不允许出现在元素“fieldsMapper”中。

我的 XML 文件如下：

<?xml version="1.0"?>
<fieldsMapper xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xmlns="https://www.company.com/core"

              sourceType="java.util.Map"
              targetType="com.company.integration.demo.Transaction"
              id="identityValidationInputMapper">
    <fields>
        <field name="msg_date1" type="Date">

        </field>

        <field name="msg[msg_date]" type="String" outputFormat="YYMMDD">

        </field>

        <field name="msg_text" type="String">
            <value>

                ]]>
            </value>
        </field>

        <field name="msg_constant_text" type="String">
            <value>NAH</value>
        </field>

        <field name="order_amount">
            <groovy>
                just groovy code
            </groovy>
        </field>
    </fields>
</fieldsMapper>

我的 fieldsMapper.xsd 如下：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema attributeFormDefault="unqualified"
           elementFormDefault="qualified"

    <xs:attribute type="xs:string" name="sourceType"/>
    <xs:attribute type="xs:string" name="id"/>
  </xs:complexType>
</xs:schema>

知道为什么我会收到此错误吗？ XML 文件有效，XSD 文件也有效。我尝试将elementFormDefault 更改为unqualified 而不是qualified，但没有任何区别。

对于初学者来说，

xsi:noNamespaceschemaLocation

应该是

xsi:noNamespaceSchemaLocation
               ^

...但是您甚至不应该使用xsi:noNamespaceSchemaLocation，因为您的 XML 位于命名空间中。请改用xsi:noNamespaceSchemaLocation。

改变

xsi:noNamespaceschemaLocation="http://www.company.com/core/fieldsMapper 
                               fieldsMapper.xsd"

到

xsi:schemaLocation="http://www.company.com/core fieldsMapper.xsd"

注意 xsi:schemaLocation 和命名空间的更改，以匹配 XML 的默认命名空间和 XSD 的 targetNamespace。
