Question

刚从

修改了我的Xml架构

.......
<xs:element name="mood1">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="positive" type="xs:boolean"/>
      <xs:element name="probability" type="xs:float"/>
    </xs:sequence>
  </xs:complexType>
</xs:element> 
<xs:element name="mood2">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="positive" type="xs:boolean"/>
      <xs:element name="probability" type="xs:float"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

到

..........  
<xs:complexType name="category">
   <xs:sequence>
     <xs:element name="positive" type="xs:boolean"/>
     <xs:element name="probability" type="xs:float"/>
   </xs:sequence>`enter code here`
 </xs:complexType>
 <xs:element name="mood1" type="category"/>
 <xs:element name="mood2" type="category"/>
 ...........

简化它。

但现在当我使用JAXB（2.2.5）为它抱怨的模式生成Java类时

 src-resolve: Cannot resolve the name 'category' to a(n) 'type definition' component.

不能jaxb处理type属性吗？

刚刚更新为 JAXB 2.2.11 ，但没有任何区别

Answer 1

当然可以。

您正在使用category而没有任何前缀。为此，请确保您xmlns="..."与架构的targetNamespace匹配。

随时发布您的完整架构供我们检查。

Jaxb可以处理Xml架构中的类型属性
